This chapter describes how to complete a basic configuration of the Cisco MGX 8850 Route Processor Module (RPM), provides procedures for configuring ATM, Ethernet, Fast Ethernet and FDDI port adapter interfaces, permanent virtual circuits (PVCs) and the connections between the RPM and the PXM and either service modules or other RPMs. This chapter contains the following sections:
This chapter provides information to get the RPM up and running. Detailed software configuration information is available in the Cisco IOS configuration and command reference publications, which are available on the Cisco Documentation CD-ROM.
To configure the RPM, you must access the command-line interface (CLI) of the RPM.
The RPM CLI can be accessed using any of the following three methods:
Each time you turn on power to the RPM (insert the RPM into the MGX 8850), it goes through the following boot sequence:
1. The RPM goes through power-on self-test diagnostics to verify basic operation of the CPU, memory, and interfaces.
2. The system bootstrap software (boot image) executes and searches for a valid Cisco IOS image (the RPM operating system software).
The source of the Cisco IOS image is determined by the configuration register setting. The factory-default setting for the configuration register is 0x2102 which means the RPM will first look for the IOS image in bootflash.
However, since the RPM-A normally has bootflash only large enough to hold the bootstrap image and not the entire IOS operating system image, boot system configuration commands must be used to override the default boot system and specify a Cisco IOS image file on a TFTP server or the PXM C: drive.
For the RPM-B the bootflash contains the entire IOS operating system image.
3. If after five attempts the boot system configuration commands each fail to find a valid IOS image on a TFTP server or on the PXM C: drive, and no valid IOS image is found in bootflash, the RPM reverts to rommon mode (which is used to install or upgrade a Cisco IOS image).
4. If a valid Cisco IOS image is found, then the RPM searches for a valid configuration file.
5. If a valid configuration file is not found in NVRAM, the RPM runs the System Configuration Dialog so you can configure it manually. For normal RPM operation, there must be a valid Cisco IOS image on a TFTP server, the PXM C: drive, or in bootflash, and a configuration file in NVRAM.
The first time you boot the RPM, you need to configure the RPM interfaces and then save the configuration to a file in NVRAM. Proceed to the next section, "Booting the RPM From the PXM" and the section, "Configuring the RPM," for instructions.
The IOS image should be stored on the PXM hard drive. To confirm this, make sure you are in the /RPM directory and use the ls command to list the contents of the directory. You should see a file named "xxx" which is the IOS image.
The following are PXM commands illustrating this command sequence:
NODENAME.1.7.PXM.a > cd C:RPM
NODENAME.1.7.PXM.a > ls
.
..
rpm-is-mz.120-4.0.1.T
In the file system :
total space : 3176712 K bytes
free space : 3067819 K bytes
NODENAME.1.7.PXM.a >
If this image is not there you will need to use the TFTP file-transfer application to load the image to the PXM hard drive.
The following is an TFTP example:
marka-u5:4> ls -l rpm-is-mz.120-4.0.1.T -rw-r--r-- 1 marka eng 4560820 Apr 2 12:16 rpm-is-mz.120-4.0.1.T marka-u5:5> tftp 172.29.37.154 tftp> bin tftp> put rpm-is-mz.120-4.0.1.T RPM/rpm-is-mz.120-4.0.1.T Sent 4560820 bytes in 41.2 seconds tftp> q marka-u5:6>
To load the IOS image from the PXM hard drive, the RPM must be configured to do so.
Before the RPM can load the IOS image from the PXM, the RPM's ATM switch interface must first be enabled. Use the Console port on the RPM to boot the RPM from Flash so that you can configure its ATM switch interface.
In configuration mode type interface switch slot/1 to access the interface configuration. Type no shutdown to activate the interface.
The following illustrated how to enable the RPM's ATM interface:
RPM(boot)#config term Enter configuration commands, one per line. End with CNTL/Z. RPM(boot)(config)#interface Switch9/1 RPM(boot)(config-if)#no shutdown RPM(boot)(config-if)# 00:06:55:%LINK-3-UPDOWN:Interface Switch9/1, changed state to up 00:06:56:%LINEPROTO-5-UPDOWN:Line protocol on Interface Switch9/1, changed sta te to up RPM(boot)(config-if)#^Z RPM(boot)# 00:07:01:%SYS-5-CONFIG_I:Configured from console by console RPM(boot)#
Now, use boot system configuration commands to override the default boot setting. Type the following configuration command to configure the RPM to boot from the PXM:
MGX8850-RPM (config)# boot system c:filename
Then reload the RPM and boot the Cisco IOS from the PXM disk.
To verify the accessibility of the PXM C:drive from the RPM, issue the following privileged-level EXEC command:
MGX8850-RPM# dir c:
Directory of c:/
-rw- 5584092 Oct 19 1999 15:39:54 rpm-js-mz.120-4.T
-rw- 1680448 Oct 19 1999 15:39:54 rpm-boot-mz.120-2.T

You can configure the RPM using Configuration Mode---Recommended if you are familiar with Cisco IOS commands.
 | TimeSaver Obtain the correct network addresses from your system administrator or consult your network plan to determine correct addresses before you begin to configure the RPM. |

Once port adapter cable connections have been made (refer to Chapter 4, "Cabling Cisco MGX 8850 RPM Port Adapters," for connector descriptions and cable attachment instructions) and basic configuration on the RPM is completed, ATM, Ethernet, Fast Ethernet and FDDI port adapter interfaces on the RPM must be configured. This is then followed by configuration of permanent virtual circuits (PVCs) and the connections between the RPM and the PXM and either service modules or other RPMs.
If you want to configure interfaces in a new RPM or if you want to change the configuration of an existing interface, be prepared with the information you will need, such as the following:
The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.
The following section describes how to identify chassis slot, port adapter slot, and interface port numbers on the RPM for all port adapter interface types.
Physical port addresses specify the actual physical location of each interface port, regardless of the type, on the RPM. In the RPM, this address is composed of a three-part number in the format chassis-slot/port adapter slot number/interface port number, as follows:
You can also identify port adapter interface ports by physically checking the slot/interface port location on the front of the RPM or by using show commands to display information about a specific interface or all interfaces in the RPM.
This section provides the procedure for a basic interface configuration.
Press Return after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
RPM-3# disable RPM-3>
Use the following procedure to perform a basic configuration:
Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows:
RPM-3# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)#
Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by switch to specify the internal ATM interface, then slot/port (for slot of the MGX 8850 chassis where the RPM is located, and for port number on the port adapter). The example that follows show the atm interface as 1 in the RPM in slot 5 of the MGX 8850:
RPM-3(config)# interface switch 5/1
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:
RPM-3(config-if)# ip address 192.168.1.10 255.255.255.0
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Change the shutdown state to up and enable the interface as follows:
RPM-3(config-if)# no shutdown
Step 6 When you have completed the configuration, press Ctrl-Z to exit configuration mode.
Step 7 Write the new configuration to nonvolatile memory as follows:
RPM-3# copy running-config startup-config [OK] RPM-3#
The Ethernet interfaces are configured to allow a connection to a LAN. To configure the interface parameters, you need to know your Ethernet interface network addresses.
Take the following basic configuration steps to configure an Ethernet interface to allow communication over a LAN:
Press Return after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
RPM-3# disable RPM-3>
Following is an example of a basic configuration procedure:
Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows:
RPM-3# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)#
Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by ethernet to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter).
Step 3 The example that follows is the 2 interface of the lower ethernet port adapter in the RPM in slot 5 of the MGX 8850:
RPM-3(config)# interface e 5/2/2
Step 4 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in this example:
RPM-3(config-int)# ip address 1.1.1.10 255.255.255.0
Step 5 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 6 Change the shutdown state to up and enable the interface as follows:
RPM-3(config-int)# no shutdown
Step 7 Configure additional interfaces as required.
Step 8 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.
Step 9 Write the new configuration to nonvolatile memory as follows:
RPM-3# copy running-config startup-config [OK] RPM-3#
To check the interface configuration using show commands, proceed to the section "Checking the Configuration."
The following steps describe a basic configuration. Press Return after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
RPM-3# disable RPM-3>
Following is an example of a basic configuration procedure:
Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows:
RPM-3# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)#
Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by fastethernet to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter). The example that follows is the 1 interface of the upper fastethernet port adapter in the RPM in slot 5 of the MGX 8850:
RPM-3(config)# interface fastethernet 5/1/1
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:
RPM-3(config-if)# ip address 1.1.1.10 255.255.255.0
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Change the shutdown state to up and enable the interface as follows:
RPM-3(config-if)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.
Step 8 Write the new configuration to nonvolatile memory as follows:
RPM-3# copy running-config startup-config [OK] RPM-3#
This completes the procedure for creating a basic configuration.
Half-duplex operation is the default transmission mode for the FE port adapters. Use the full-duplex command to configure full-duplex operation for the FE port adapters as follows:
RPM-3# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)# RPM-3(config)# interface fastethernet 5/2/1 RPM-3(config-if)# full-duplex Ctrl-z
Use the show interfaces fastethernet command to verify that the 2/1 Fast Ethernet interface is now configured for full-duplex operation as follows:
RPM-3# sh int fastethernet 5/2/1 FastEthernet 5/2/1 is administratively up, line protocol is up (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX
Use the no full-duplex command to return the interface to half-duplex operation as follows:
RPM-3# config t Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)# int fastethernet 5/2/1 RPM-3(config-if)# no full-duplex Ctrl-z RPM-3#
Use the show interfaces fastethernet command to verify that the 2/1 Fast Ethernet interface is now configured for half-duplex operation as follows:
RPM-3# sh int fastethernet 5/2/1 FastEthernet5/2/1 is administratively up, line protocol is up (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX (display text omitted)
The RJ-45 receptacle is the default media type for FE-TX port adapter and the SC receptacle (for fiber-optic connections) is the default media type for FE-FX port adapter. Use the media-type mii command to configure the MII receptacle as the media type for the FE port adapters as follows:
RPM-3# config t Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)# int fa 5/2/1 RPM-3(config-if)# media-type mii Ctrl-z RPM-3# sh int fa 5/2/1 FastEthernet2/1 is administratively up, line protocol is up (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII (display text omitted)
Use the media-type 100 command to return the media type for the FE port adapters to the RJ-45 receptacle or SC receptacle.
To check the interface configuration using show commands, proceed to the section "Configuring 4E Interfaces".
This section provides the procedures for performing a basic configuration of the interfaces on full-duplex FDDI port adapters installed in a RPM.
Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
RPM-3# disable RPM-3>
Use the following procedure to perform a basic configuration:
Step 1 At the privileged-level prompt, enter configuration mode. Specify that the console terminal will be the source of the configuration subcommands, as follows:
RPM-3# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)#
Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by fddi to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter). The example that follows is the 1 interface of the upper fddi port adapter in the RPM in slot 5 of the MGX 8850:
RPM-3(config)# interface fddi 5/1/1
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:
RPM-3(config-if)# ip address 1.1.1.10 255.255.255.0
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Change the shutdown state to up and enable the interface as follows:
RPM-3(config-if)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.
Step 8 Write the new configuration to nonvolatile memory as follows:
RPM-3# copy running-config startup-config [OK] RPM-3#
To check the interface configuration using show commands, proceed to the section "Configuring FDDI Interfaces".
Full-duplex operation requires FDDI port adapters PA-F/FD-SM or PA-F/FD-MM.
Full-duplex operation is not the default configuration and must be turned on using the full-duplex command. To turn off full-duplex operation (and enable half-duplex operation) and reset the interface, use the no full-duplex (or half-duplex) command.
Following is an example of configuring an FDDI interface for full-duplex operation using the full-duplex command:
RPM-3# conf t Enter configuration commands, one per line. End with CNTL/Z. RPM-3(config)# int fddi 5/2/1 RPM-3(config-if)# full-duplex Ctrl-z RPM-3#
The output of the show interfaces fddi slot/card/port command displays the state of the FDDI port adapter interface and the state of full-duplex operation. Following is a partial sample output of this command from an FDDI interface with full-duplex operation enabled:
RPM-3# show int fddi 5/2/1 Fddi5/4/0 is up, line protocol is up Hardware is MIF68840_MM, address is 0060.7054.8808 (bia 0060.7054.8808) Internet address is 2.1.1.3/24 MTU 4470 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 9/255 Encapsulation SNAP, loopback not set, keepalive not set ARP type: SNAP, ARP Timeout 04:00:00 FDX supported, FDX enabled, FDX state is *
where *, in the last line, could be idle, request, confirm, or operation, depending on the state the FDDI interface was in when the show interfaces command is entered.
When full-duplex operation is turned off using the no full-duplex (or half-duplex) command, the last line of the preceding display includes the following information: FDX supported, FDX disabled. If the port adapter does not support full-duplex, the message FDX NOT supported is displayed.
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and the ping command to check connectivity.
The following steps use show commands to verify that the new interfaces are configured and operating correctly.
Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new interfaces.
Step 2 Display all the current port adapters and their interfaces with the show controllers command.
Step 3 Specify one of the new interfaces with the show interfaces port adapter type slot/card/interface command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.
Step 5 Display the running configuration file with the show running-config command.
Step 6 Display the configuration stored in NVRAM using the show startup-config command. Verify that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance. For detailed software configuration information, refer to the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that came with your RPM, or you can order printed copies.
To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/card/port] for the MGX 8850 RPM.
Following is an example of how the show interfaces [type slot/card/port] command displays status information (including the chassis physical slot, card number and port address) for the interfaces you specify. In these examples, the four Ethernet 10BASE-T interfaces (1-4) are in the lower port adapter in the RPM in slot 4 of the MGX 8850 (interfaces are administratively shut down until you enable them).

With the show interfaces type slot/card/port command, use arguments such as the interface type (ethernet, and so forth), slot, card and the port number (slot/card/port) to display information about a specific Ethernet 10BASE-T interface only.
The show version (or show hardware) command displays the configuration of the system hardware (the number of each port adapter type installed), the software version, the names and sources of configuration files, and the boot images. Following is an example of the show version command:

Proceed to the next section "Using the ping Command" to verify that each interface port is functioning properly.
The packet internet groper (ping) command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. This section provides brief descriptions of the ping command. After you verify that the system has booted successfully and is operational, you can use this command to verify the status of interface ports.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.
Following is an example of a successful ping command to a remote server with the address 1.1.1.10:
RPM-3# ping 1.1.1.10 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 1.1.1.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms RPM-3#
If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on). Repeat the ping command.
A VC is a point-to-point connection between two or more devices. This section describes how to configure a PVC originating on the RPM ATM interface and terminating on a service module within a single MGX 8850 or on another RPM.
A VC is established for each ATM end node with which the RPM communicates. The characteristics of the VC are established when the VC is created and include the following:
Each RPM VC supports the following router functions:
Like the other card modules in the MGX 8850 switch, resource partitions must be defined on the RPM. The rpmrscprtn command defines the bandwidth and addressing resources assigned to each controller (PAR, Tag or PNNI).
The rpmrscprtn command is used to modify the resource partitioning on the RPM. It is necessary to use the rpmrscprtn command before you add any PVCs or connections to the RPM because by default all partitions are disabled.
Type in the following command to set up resource partitioning:
RPM-3(config)# rpmrscprtn PAR 100 100 1 255 0 3840 4047 Partition type [par|tag|pnni] Percent ingress [<0-100>] Percent egress [<0-100>] Minimum VPI [<0-255>] Maximum VPI [<0-255> Minimum VCI [<0-3840>] Maximum VCI [<0-3840>] Number of LCNs [<0-4047>]
Table 5-1 describes rpmrscprtn command parameters.
| Parameter | Description |
|---|---|
par | tag | pnni | The controller type that you want to define. |
ingress-percent | The percentage of the ingress bandwidth on the ATM switch interface that can be allocated by the controller type. The aggregate of the ingress bandwidth across all three controllers can exceed 100 percent. |
egress-percent | The percentage of the egress bandwidth on the ATM switch interface that can be allocated by the controller type. The aggregate of the egress bandwidth across all three controllers can exceed 100 percent. |
min-vpi | The minimum VPI value that can be assigned on PVCs on this controller. The VPI range on the three controllers can overlap. |
max-vpi | The maximum VPI value that can be assigned on PVCs on this controller. The VPI range on the three controllers can overlap. |
min-vci | The minimum VCI value that can be assigned on PVCs on this controller. Unlike the VPI range, the VCI range cannot overlap the VCI range of another controller. |
max-vci | The maximum VCI value that can be assigned on PVCs on this controller. Unlike the VPI range, the VCI range cannot overlap the VCI range of another controller. |
Icns | The total number of logical connections that can use this controller. |
All permanent virtual circuits (PVCs) configured into the RPM remain active until the circuit is removed from the configuration. The PVCs also require a permanent connection to the ATM switch. All virtual circuit characteristics apply to PVCs. When a PVC is configured, all the configuration options are passed on to the ATM port adapter. These PVCs are writable into the nonvolatile RAM (NVRAM) as part of the RPM configuration and are used when the RPM image is reloaded.
Each PVC on the RPM is associated with a subinterface. Some subinterfaces support multiple PVCs (multipoint) that do the equivalent of broadcasting. Others only support one PVC (point-to-point). If a point-to-multipoint PVC exists, then that PVC can be used as the sole broadcast PVC for all multicast requests.
Each subinterface is identified as slot/interface.subinterface. The slot is the card slot number of the RPM, the interface is always 1, and the subinterface is a number that identifies the subinterface PVCs on the RPM.
A subinterface is created while in the configuration mode by typing the interface switch command. The IP address is set using the ip address command.
To configure a PVC, you must perform the following tasks:
Step 1 Create a point-to-point or multipoint subinterface.
Step 2 Assign an IP address to the subinterface.
Step 3 Create an ATM PVC.
Step 4 Define a map list (for multipoint only).
Step 5 Add a connection between the RPM and the PXM.
Step 6 Add the remaining connection segments as needed.
Refer to the document, MGX 8850 Wide Area Switch Installation and Configuration, for more information on creating PVCs on the RPM and the rest of the Cisco 7000 family of routers. Also refer the section, "Configuring Connections between the RPM and Other Devices," later in this chapter.
When you create a PVC, you create a virtual circuit descriptor (VCD) and attach it to the virtual path identifier (VPI) and virtual channel identifier (VCI). A VCD is an ATM port adapter-specific mechanism that identifies to the ATM port adapter which VPI/VCI to use for a particular packet. The ATM port adapter requires this feature to manage packets for transmission. The number chosen for the VCD is independent of the VPI/VCI used. When you create a PVC, you also specify the AAL and encapsulation. A rate queue is used that matches the default peak and average rate, which are equal, and are specified in kilobits per second. To create a PVC on the ATM port adapter interface, use the atm pvc command. To remove a PVC, use the no form of this command.
atm pvc vcd vpi vci aal-encap no atm pvc vcd
RPM:
RPM-3(config)# interface switch chassis-slot/1.subinterface interface-type
Where the interface-type is either point-to-point, multipoint or tag.
RPM-3(config-if)# atm pvc 2048 255 128 aal5snap
vcd---A unique index value describing this VC in the range of 1 to MAXVC (defined when setting up resource partitioning). Do not use VCD 1, as this is hardcoded.
vpi---The ATM network VPI to use for this VC in the range of 0 through 255. A VPI of 0 indicates that this PVC is a VCC. A non-0 value indicates that the PVC is a VPC.
vci---The ATM network VCI to use for this VC in the range of 0 through 3,824.
aal-encap---The encapsulation type to use on this VC from the following:
The atm pvc command creates PVC n and attaches the PVC to VPI and VCI. The AAL used is specified by aal and encapsulation by encap.
The default for peak rate and average rate is that peak = average, and the PVC is automatically connected to the highest bandwidth rate queue available. For detailed software configuration information, refer to the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that came with your RPM, or you can order printed copies.
Cisco IOS software supports a mapping scheme that identifies the ATM address of remote hosts/RPMs. This address can be specified either as a VCD for a PVC or a network service access point (NSAP) address for SVC operation.
Enter mapping commands as groups; multiple map entries can exist in one map list. First create a map list, then associate the list with an interface.
Enter the map-list name command; then enter the protocol, protocol address, and other variables, as follows:
map-list name
protocol-type protocol-address [atm-vc vcd] | atm-nsap nsap-address] [broadcast]
The broadcast keyword specifies that this map entry receives the corresponding protocol broadcast requests to the interface (for example, any network routing protocol updates). If you do not specify broadcast, the ATM software is prevented from sending routing protocol updates to the remote hosts.
After you create the map list, specify the ATM interface to which it applies with the interface command, as follows:
RPM usage:
RPM-3# interface switch 5/1
Associate the map list to an interface with the following command:
map-group name
You can create multiple map lists, but only one map list can be associated with an interface. Different map lists can be associated with different interfaces. The following is an example of the commands to map a list to an interface on a RPM:
RPM-3# interface switch 5/1 ip address 1.1.1.2 255.255.255.0 map-group atm1 atm pvc 2 0 1 aal5snap ! no ip classless ! map-list atm1 ip 1.1.1.1 atm-vc 2 broadcast
After configuring port adapters on the RPM, the next step is to configure connections between the RPM and other devices (service modules, other RPMs) via the PXM.
The PXM (the main processor on the MGX 8850) coordinates all communication between the RPM and service modules and other RPMs. See Figure 5-1 for a view of how service modules sit in the MGX 8850 and their physical relationship to the PXM and RPM.
A complete connection between the RPM and any of these devices includes two parts:
Initially, you set up the connection between the RPM and the PXM.
For the RPM in slot 5 connecting to slot 2 perform the following steps:
Step 1 Set up physical interface:
RPM-3# conf t RPM-3(config)# int sw5/1 RPM-3(config)# no shut
Step 2 Set up logical interface:
RPM-3(config)# int sw 5/1.1 point-to-point ip address 1.0.0.1 255.0.0.0
Step 3 Set up pvc:
RPM-3(config-if)# atm pvc 2 0 1 aal5snap
Step 4 To get back to the global level, type exit:
RPM-3(config-if)# exit RPM-3(config)#
Step 5 Then, type in the following command to set up resource partitioning:
RPM-3(config)# rpmrscprtn PAR 100 100 1 255 0 3840 4047 Partition type [par|tag|pnni] Percent ingress [<0-100>] Percent egress [<0-100>] Minimum VPI [<0-255>] Maximum VPI [<0-255> Minimum VCI [<0-3840>] Maximum VCI [<0-3840>] Number of LCNs [<0-4047>]
Step 6 Add a connection to the pvc, either vcc (virtual circuit connection) or vpc (virtual path connection):
RPM-3(config)# addcon vcc Switch slot/1[.sub-interface] vci [rname rname] rslot rslot r_int r_vpi r_vci [master {local | remote}]
or
RPM-3(config)# addcon vpc Switch slot/1[.sub-interface] vpi [rname rname] rslot rslot r_int r_vpi [master {local | remote}]

To complete a RPM-to-service module connection, you then configure the connection between the service module and the PXM.
Service modules can be of various types including FRSM (Frame Relay), AUSM (ATM UNI), CESM (Circuit Emulation) and VISM (Voice).
The AUSM-8T1/E1 is a multipurpose card that supports up to 8 T1 or E1 ports.
The Circuit Emulation Service Module (CESM) emulates leased lines/circuits over an ATM network. It converts DS1/E1 or data streams into CBR AAL1 cells for transport across the network. The T1/E1 versions support either structured or unstructured data transfer on a per-physical interface basis.
VISM is a multi-DSP co-processing card and software package that adds voice over IP capabilities to the MGX 8850 platform. The MGX 8850 utilizes this new feature card along with LAN/WAN routing capabilities to provide a 192/240 channels gateway for VoIP packetized voice traffic to and from TDM traffic.
The Frame Service Module (FRSM) is a two-card set consisting of an FRSM front card (channelized or fractional, T1 or E1, 8 port) and either an 8T1, or 8E1 port adapter. The FRSM converts Frame Relay packets into ATM cells.
Service modules can be configured to forward data to the RPMs in one of two modes: port forwarding or connection forwarding.
In this mode, all frames received on a port are forwarded to the router for L3 processing. For example, a FRSM T1 could be configured for PPP IP access by:
Step 1 Setting up a frame forwarding (FF) connection from a FRSM T1 port to the RPM cellbus address on VPI/VCI.
Step 2 Configuring the router to terminate PPP frames forwarded over an ATM connection on the ATM Deluxe Port Adaptor port on VCI 0/xFrame-forwarding (a proprietary method whereby all HDLC frames received on a port are converted to ATM AAL5 frames with a null encapsulation and sent over a single VC). Cisco has already implemented code to terminate frame-forwarded PPP over ATM.
The data flow for a PPP connection destined for the RPM is shown in the figure below. The packet enters the FRSM module as PPP and is frame forwarded to the RPM. The RPM receives the packet in PPP over ATM because MGX 8850 internal connectivity is ATM. The RPM is running software that understands PPP over ATM encapsulation, allowing the router to reach the IP layer and route the packet to its destination (i.e. the Internet). Packets then destined to the Internet via a WAN network are then sent back to the PXM, and out the ATM uplink.
In this example, the FRSM is in slot 18 and RPM A is in slot 12. A serial port on Router B is connected to the FRSM line 1.

In this mode all frames received on a given connection are forwarded to the router using the appropriate ATM encapsulation. For example, Frame Relay connections on a FRSM port could be forwarded to the RPM by:
The data flow for a native Frame Relay connection destined to the RPM is shown in Figure 5-3. This data flow is identical to that of PPP packets, but the encapsulation techniques are different. Standard Frame Relay is encapsulated using RFC1490. When a packet is received at the FRSM encapsulated using RFC1490, standard FR-ATM service interworking translation mode (FRF.8) is performed so that when the packet is forwarded to the RPM it is encapsulated using RFC1483. The router also understands RFC1483 allowing it to reach the IP layer, and route the packet.
In this example, the FRSM-8T1 is in slot 18 of the MGX 8850, while the RPM is in slot 12.

The ATM UNI Service Modules (AUSMs) provide native ATM UNI (compliant with ATM Forum v3.0, v3.1, and v4.0) interfaces at T1 and E1 speeds, with eight ports per card, providing up to
16 Mbps of bandwidth for ATM service interfaces.
Consistent with Cisco's Intelligent QoS Management features, AUSM cards support per-VC queuing on ingress and multiple class-of-service queues on egress. AUSM cards fully support continuous bit rate (CBR), variable bit rate (VBR), unspecified bit rate (UBR), and available bit rate (ABR) service classes.
The AUSM-8 cards also support ATM Forum-compliant inverse multiplexing for ATM (IMA). This capability enables multiple T1 or E1 lines to be grouped into a single high-speed ATM port. This
N x T1 and N x E1 capability fills the gap between T1/E1 and T3/E3, providing bandwidth up to
12 Mbps (N x T1) or 16 Mbps (N x E1) without requiring a T3/E3 circuit.
A single AUSM card can provide hot standby redundancy for all active AUSM cards of the same type in the shelf (1:N redundancy).
AUSM modules are supported by standards-based management tools, including SNMP, TFTP (for configuration and statistics collection), and a command line interface. Cisco's WAN Manager application suite also provides full graphical user interface support for connection management, and CiscoView software provides equipment management.
Table 5-2 below summarizes the key attributes of the AUSM cards:
| AUSM-8T1 | AUSM-8E1 | |
| Physical interface | T1 | E1 |
| Number of ports | 8 | 8 |
| Line Speed | 1.544 Mbps +/- 50 bps | 2.048 Mbps +/- 50 bps |
| Logical ports | 8 maximum | 8 maximum |
| Maximum connections | 1000 | 1000 |
| Line coding | B8ZS AMI | HDB3 AMI |
| BERT | Yes | Yes |
| Loopback | Extended loopback pattern generation and verification | Loop-up, loop-down pattern generation and verification |
| Redundancy | 1:N | 1:N |
| Port Adapters | RJ48-8T1 R-RJ48-8T1 | RJ48-8E1 R-RJ48-8E1 |
The following procedure may be used for configuring the FRSM and CESM connection to the PXM. The AUSM is slightly different and is in the section, "Setting Up the AUSM Connection to PXM," later in this chapter.
Step 1 Go to the PXM and login.
Step 2 Then, cc to the slot where the service module is:
prompt# cc 12
Step 3 Type dsplns to see interfaces:
prompt# dsplns
Step 4 To establish the physical connection between the service module and the PXM, enable a line with the command addln:
prompt# addln 2
Step 5 Display ports:
prompt# dspports
Step 6 Add a port:
prompt# addprt port_num line_num port_type
Step 7 Display ports:
prompt# dspports
Step 8 Choose signalling type:
prompt# xcnfport "-pt" <PortNum) -sig (type)" <cr>
Step 9 Now configure the logical link between the service module and the PXM by typing the command addcon:
prompt# addcon "port dlci cir chan_type [CAC] [Controller_Type][mastership] [remoteConnId]"
where parameters are:
port number --- values ranging from 1-192 are accepted for T1 and 1-248 for E1
DLCI number --- value ranging from 0 to 1023
committed rate --- 0-1536000 bps for T1; 0-2048000 bps for E1
chan type --- values 1-5:
CAC --- Connection Admission Control (optional); 1 = enable, 2 = disable (default)
Controller Type (Signalling) --- 1:PVC (PAR) - Default , 2:SPVC (PNNI)
mastership --- 1 for master, 2 for slave
Remote end Connection ID --- Format :

For detailed configuration examples, refer to the router software publications listed in the first paragraph in the preface "About This Manual" at the beginning of this document. The following sections contain examples of ATM interface configurations:
For examples of emulated LAN configurations, refer to the document, MGX 8850 Wide Area Switch Installation and Configuration.
The following example creates PVC 5 on the ATM interface 5/1 using LLC/SNAP encapsulation over AAL5. ATM interface 5/1 (IP address 1.1.1.2 255.255.255.0) connects with the ATM interface (IP address 1.1.1.1 255.255.255.0) at the other end of the connection. The static map list named atm1 declares that the next node is a broadcast point for multicast packets from IP.

The following example is of a typical ATM configuration for a PVC:
interface switch 5/1 ip address 131.108.168.112 255.255.255.0 map-group atm atm pvc 2 2 2 aal5snap atm pvc 6 6 6 aal5snap atm pvc 7 7 7 aal5snap clns router iso-igrp comet ! router iso-igrp comet net 47.0004.0001.0000.0c00.6666.00 ! router igrp 109 network 131.108.0.0 ! ip domain-name CISCO.COM ! map-list atm ip 131.108.168.110 atm-vc 7 broadcast clns 47.0004.0001.0000.0c00.6e26.00 atm-vc 6 broadcast atm-vc 2 broadcast
The configurations for RPMs A, B, and C follow. In this example, the RPMs are configured to use PVCs. Fully meshed indicates that each network node has either a physical circuit or a virtual circuit connecting it to every other network node. Note that the two map-list statements configured in RPM A identify the ATM addresses of RPMs B and C. The two map-list statements in RPM B identify the ATM addresses of RPMs A and C. The two map list statements in RPM C identify the ATM addresses of RPMs A and B. Figure 5-4 illustrates a fully meshed network.

You can configure the RPM manually if you prefer not to use AutoInstall or the prompt-driven System Configuration Dialog.
Take the following steps to configure the RPM manually:
Step 1 Connect a console terminal to the RPM.
Follow the instructions described in Chapter 3, "Installing the Cisco MGX 8850 RPM," in the section "Connecting a Terminal or PC to the MGX 8850 RPM Console Port," and then power ON the RPM.
Step 2 When you are prompted to enter the initial dialog, enter no to go into the normal operating mode of the RPM:
Would you like to enter the initial dialog? [yes]: no
Step 3 After a few seconds you will see the user EXEC prompt (Router>).
By default, the host name is Router, but the prompt will match the current host name. In the following examples, the host name is MGX8850-RPM. Enter the enable command to enter enable mode. You can only make configuration changes in enable mode:
MGX8850-RPM> enable
The prompt will change to the privileged EXEC (enable) prompt, MGX8850-RPM#.
Step 4 Enter the configure terminal command at the enable prompt to enter configuration mode:
MGX8850-RPM# config terminal
You can now enter any changes you want to the configuration. You will probably want to perform the following tasks:
(a) Assign a host name for the RPM using the hostname command.
(b) Enter an enable secret using the enable secret command.
(c) Enter an enable password using the enable password command.
(d) Assign addresses to the interfaces using the protocol address command.
(e) Specify which protocols to support on the interfaces.
Refer to the Cisco IOS configuration and command reference publications for more information about the commands you can use to configure the RPM. You can also refer to the MGX 8850 Wide Area Switch Command Reference and MGX 8850 Wide Area Switch Installation and Configuration documents for information about the commands you can use to configure the RPM.
Step 5 When you finish configuring the RPM, enter the exit command until you return to the privileged EXEC prompt (MGX8850-RPM#).
Step 6 To save the configuration changes to NVRAM, enter the copy running-config startup-config command at the privileged EXEC prompt:
MGX8850-RPM# copy running-config startup-config ********
The RPM is now configured and will boot with the configuration you entered.
This concludes the initial RPM configuration.
When you have installed and configured the RPM, you can use the following commands in user EXEC mode to verify network connectivity:
If there is a problem with network connectivity, refer to Appendix A, "Maintaining the Cisco MGX 8850 RPM," in the section "Reading Front Panel LEDs," and check the cable connections. If there is still a problem, check the RPM configuration. Contact customer service for further assistance.
You can enter multiple boot commands in the configuration in NVRAM to provide a backup method for loading the Cisco IOS image onto the RPM. The RPM boots using the first boot command that succeeds. If you enter multiple boot commands, the RPM executes them in the order they are entered. There are two ways to load the Cisco IOS image: from the PXM hard drive or from a TFTP server on the network.
MGX8850-RPM> enable Password: enablepassword MGX8850-RPM# configure terminal MGX8850-RPM (config)# boot system c:filename MGX8850-RPM (config)# Ctrl-Z MGX8850-RPM# copy running-config startup-config Building configuration ... [OK] MGX8850-RPM# exit MGX8850-RPM>
2. TFTP server
MGX8850-RPM> enable Password: enablepassword MGX8850-RPM# configure terminal MGX8850-RPM (config)# boot system tftp filename ipaddress MGX8850-RPM (config)# Ctrl-Z MGX8850-RPM# copy running-config startup-config Building configuration ... [OK] MGX8850-RPM# exit MGX8850-RPM>
3. PXM C: drive
The RPM has access to the file system on the PXM C:drive, in the C:RPM directory. Use the Console port on the RPM to boot the RPM from Flash so that you configure its ATM switch interface as no shutdown. This then lets you access the c: drive on the PXM and copy files to the startup config or to bootflash.
In the following example, replace filename with the filename of the Cisco IOS image. Type the following commands to boot the RPM from the PXM and copy files:
MGX8850-RPM> enable Password:enablepassword MGX8850-RPM# configure terminal MGX8850-RPM (config)# boot system c:filename MGX8850-RPM (config)# Ctrl-Z MGX8850-RPM# copy running-config startup-config Building configuration ... [OK] MGX8850-RPM# *****
Then reload the RPM to get back to rommon and then boot full IOS from the PXM disk.
This section provides you with some basic information about the Cisco IOS software and includes the following sections:
Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.
For security purposes, Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
Table 5-3 describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you.
| Mode of Operation | Usage | How to Enter the Mode | Prompt |
|---|---|---|---|
User EXEC commands allow you to connect to remote devices, change terminal settings on a temporary basis, perform basic tests, and list system information. The EXEC commands available at the user level are a subset of those available at the privileged level. | Log in. | MGX8850-RPM> | |
Privileged EXEC commands set operating parameters. The privileged command set includes those commands contained in user EXEC mode, and also the configure command through which you can access the remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as debug. | From user EXEC mode, enter the enable EXEC command. | MGX8850-RPM# | |
Global configuration commands apply to features that affect the system as a whole. | From global configuration mode, enter the configure privileged EXEC command. | MGX8850-RPM(config)# | |
Interface configuration | Interface configuration commands modify the operation of an interface such as an Ethernet or serial port. Many features are enabled on a per-interface basis. Interface configuration commands always follow an interface global configuration command, which defines the interface type. | From global configuration mode, enter the interface type number command. For example, enter the interface int switch 9/1 command to configure the ATM interface. | MGX8850-RPM(config-if)# |
ROM monitor commands are used to perform low- | From privileged EXEC mode, enter the reload EXEC command. Press Break during the first 60 seconds while the system is booting. | > |
| 1You can modify the configuration register value using the config-reg configuration command. Refer to Appendix A, "Maintaining the Cisco MGX 8850 RPM," in the section "Virtual Configuration Register Settings" for more information. |
Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, enter the no ip routing command and enter ip routing to reenable it. The Cisco IOS software command reference publication provides the complete syntax for the configuration commands and describes what the no form of a command does.
In any command mode, you can get a list of available commands by entering a question mark (?).
MGX8850-RPM> ?
To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.
MGX8850-RPM# co? configure connect copy
To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.
MGX8850-RPM# configure ? memory Configure from NV memory network Configure from a TFTP network host terminal Configure from the terminal <cr>
You can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh.
Whenever you make changes to the RPM configuration, you must save the changes to memory so they will not be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration. The running configuration is stored in RAM; the startup configuration is stored in NVRAM.
To display the current running configuration, enter the show running-config command. Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM.
MGX8850-RPM> enable MGX8850-RPM# copy running-config startup-config
To display the startup configuration, enter the show startup-config command. Enter the copy startup-config running-config command to write the startup configuration to the running configuration.
MGX8850-RPM> enable MGX8850-RPM# copy startup-config running-config
To erase both configuration files (and start over), enter the write erase and reload commands:
MGX8850-RPM> enable MGX8850-RPM# write erase MGX8850-RPM# reload
 | Warning This command sequence will erase the entire RPM configuration in RAM and NVRAM and reload the RPM. |
