To continue your PA-A3 port adapter installation, you must configure the PA-A3 interface. The instructions that follow apply to all supported platforms. Minor differences between the platforms---with Cisco IOS software commands---are noted.
This chapter contains the following sections:
You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:
Router> enable
Password:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#
To configure the new interface, proceed to the next section "Configuring the Interface."
After you verify that the new PA-A3 is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. Have the following information available:
If you installed a new PA-A3 or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interface. If you replaced a PA-A3 that was previously configured, the system recognizes the new interface and brings it up in its existing configuration.
For a summary of the configuration options available and instructions for configuring the interface on a PA-A3, refer to the appropriate configuration publications listed in the "Related Documentation" section.
You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the "Using the EXEC Command Interpreter" section for an explanation of the privileged level of the EXEC.)
This section contains the following subsections:
Before you remove an interface that you will not replace or replace port adapters, use the shutdown command to shut down (disable) the interface to prevent anomalies when you reinstall the new or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.
Follow these steps to shut down an interface:
Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 3 Shut down the interface by entering the interface atm subcommand (followed by the interface address of the interface), and then enter the shutdown command. Table 4-1 shows the command syntax.
When you have finished, press Ctrl-Z---hold down the Control key while you press Z---or enter end or exit to exit configuration mode and return to the EXEC command interpreter.

Step 4 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config [OK] Router#
The system displays an OK message when the configuration has been stored in NVRAM.
Step 5 Verify that new interface is now in the correct state (shut down) using the
show interfaces command (followed by the interface type and interface address of the interface) to display the specific interface. Table 4-2 provides examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | show interfaces atm, followed by slot/port (port-adapter-slot-number/ | The example is for interface 0 on a PA-A3 in port adapter slot 1.

Router# show interfaces atm 1/1/0 ATM 1/1/0 is administratively down, line protocol is down [Additional display text omitted from this example] |
Step 6 Reenable the interface by doing the following:
a. Repeat Step 3 to reenable an interface. Substitute the no shutdown command for the shutdown command.
b. Repeat Step 4 to write the new configuration to memory. Use the copy running-config startup-config command.
c. Repeat Step 5 to verify that the interface is in the correct state. Use the
show interfaces atm command followed by the interface address of the interface.
For complete descriptions of software configuration commands, refer to the publications listed in the "Related Documentation" section.
The following steps describe a basic interface configuration. 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:
Router# disable Router>
Follow these steps to perform a basic configuration:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 2 Specify the first interface to configure by entering the interface atm subcommand, followed by the interface address of the interface you plan to configure. (The PA-A3 has only one interface.) Table 4-3 gives examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | interface atm, followed by slot/port (port-adapter-slot-number/ | The example is for the interface of a PA-A3 in port adapter slot 0. Switch(config)# interface atm 0/0 Switch(config-if)# |

Cisco uBR7246 and Cisco uBR7246 VXR routers | interface atm, followed by slot/port (port-adapter-slot-number/ | The example is for the interface of a PA-A3 in port adapter slot 2. Router(config)# interface atm 2/0 Router(config-if)# |
VIP2 or VIP4 in Cisco 7000 series or Cisco 7500 series routers | interface atm, followed by slot/port adapter/port (interface-processor-slot-number/ | The example is for the interface of a PA-A3 in port adapter slot 1 of a VIP2 or VIP4 in interface processor slot 1. Router(config)# interface atm 1/1/0 Router(config-if)# |
Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address subcommand, as in the following example:
Router(config-if)# ip address 10.0.0.0 10.255.255.255
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Reenable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)
Step 6 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z---hold down the Control key while you press Z---or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.
Step 7 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config [OK] Router#
The system displays an OK message when the configuration has been stored in NVRAM.
 |
Note If you are going to disconnect or reconfigure the ATM interface cable, use the shutdown command before doing so. After reattaching the ATM interface cable, use the no shutdown command to bring up the ATM interface. |
After configuring the interface, use the show commands to display the status of the new interface and use the ping and loopback commands to check connectivity. This section includes the following subsections:
Table 4-4 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-A3 appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section.

You have completed a basic interface configuration. Depending on your version of the PA-A3, you might need to specify configuration for T3 (DS-3), E3, or OC-3c. Proceed to the next section, "Performing an Advanced Configuration," for configuration commands specific to T3, E3, or OC-3c PA-A3 port adapters, and to configure ATM-specific features.
|
Note To verify your network connectivity, see the "Using the ping Command to Verify Network Connection" section, for a brief description of the ping command. For complete descriptions of interface subcommands and the configuration options available for ATM interfaces and functionality, refer to the publications listed in the "Related Documentation" section. |
The following sections describe the advanced configuration tasks you perform to change default values on your PA-A3:
The following sections include steps for configuring and customizing various ATM features of your PA-A3 port adapter:
To configure the PA-A3 T3 port for digital signal level 3 (DS-3) framing, perform the following tasks in interface configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# interface atm slot/port or slot/port-adapter/port | Specify an ATM interface to configure. To use these commands, you need to be in interface configuration mode. (For the appropriate interface address to use for your system, see Table 4-3.) |
Step 2 | Router(config-if)# atm lbo {short | long}
| Set the line build-out length (0 to 50 feet is short and > 50 feet is long). Use the no form of this command to return to the default, short. |
Step 3 | Router(config-if)# atm clock internal | Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of the command. By default, the receive clock source is used for the transmit clock. |
Step 4 | Router(config-if)# atm DS3-scramble | Enable DS-3 scrambling. Use the no form of this command to restore the default value. |
Step 5 | Router(config-if)# atm framing | Specify DS-3 framing: m23plcp, cbitplcp, m23adm, or cbitadm. Use the no form of this command to return to the default, cbitadm. |
To configure the PA-A3 for E3, perform the following steps in interface configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# interface atm slot/port or slot/port-adapter/port | Specify an ATM interface to configure. To use these commands, you need to be in interface configuration mode. (For the appropriate interface address to use for your system, see Table 4-3.) |
Step 2 | Router(config-if)# atm clock internal | Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of the command. By default, the receive clock source is used for the transmit clock. |
Step 3 | Router(config-if)# atm e3-scramble | Enable E3 scrambling. (E3 scrambling is on by default.) Use the no form of this command to remove scrambling. |
Step 4 | Router(config-if)# atm framing {g832adm | g751adm | g751plcp}
| Specify E3 framing: g832adm, g751adm, or g751plcp. Use the no form of this command to return to the default, g832 adm framing. |
To configure the PA-A3 for OC-3, perform the following tasks in interface configuration mode:
:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# interface atm slot/port or slot/port-adapter/port | Specify an ATM interface to configure. To use these commands, you need to be in interface configuration mode. (For the appropriate interface address to use for your system, see Table 4-3 on page -7.) |
Step 2 | Router(config-if)# atm clock internal | Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of the command. By default, the receive clock source is used for the transmit clock. |
Step 3 | Router(config-if)# atm sonet stm-1 | Specify SONET framing: stm-1 (optional). Use the no form of this command to return to the default, sts-3c framing. |
A virtual circuit (VC) is a point-to-point connection between remote hosts and routers. A VC is established for each ATM end node with which the router communicates. The characteristics of the VC are established when the VC is created and include the following:
When you assign class of service to a VC for QoS management, the following default priority levels apply:
1. Operation, Administration, and Maintenance (OAM) and signaling (highest level)
2. Non-real-time variable bit rate (nrt-VBR)
3. Available bit rate (ABR) (available in the future)
4. Unspecified bit rate (UBR), ILMI (lowest level)
Each VC supports the following router functions:
By default, fast switching is enabled on all PA-A3 interfaces. These switching features can be turned off with interface configuration commands. Optimum/flow/CEF switching must be explicitly enabled for each interface.
To use a permanent virtual circuit (PVC), you must configure the PVC in both the router and the ATM switch. PVCs remain active until the circuit is removed from either configuration.
When a PVC is configured, all of the configuration options are passed on to the PA-A3. You can write these PVCs into nonvolatile RAM (NVRAM); they are used when the system image is reloaded.
Some ATM switches might have point-to-multipoint PVCs that do the equivalent of broadcasting. If a point-to-multipoint PVC exists, it can be used as the sole broadcast PVC for all multicast requests.
To configure a PVC, perform the two required tasks in the following sections:
To create a PVC on the PA-A3 interface, enter the following command in interface configuration mode:
Router(config-if)# atm pvc vcd vpi vci aal-encap [peak average {burst}] [oam {seconds}] [{inarp {minutes}]
Where the command values are as follows:
The atm pvc command creates PVC n and attaches the PVC to VPI and VCI. When you create any PVC, you also specify the ATM adaptation layer (AAL) and encapsulation. The AAL used is specified by aal and encapsulation by encap.
The peak and avg rate selection values are specified in kilobits per second. Omitting peak and average values causes the PVC and those values to default to the line rate, with the peak and average values being equal.
You can configure the PVC for communication with ILMI, which enables the router to receive Simple Network Management Protocol (SNMP) traps and new network prefixes. Refer to the Wide-Area Networking Configuration Guide for details.
You can also configure the PVC to send OAM F5 loopback cells, which verify connectivity on the virtual circuit. The remote end must respond by echoing back such cells.
The following example creates a PVC on interface 0 in a Cisco 7200 series router with a port adapter in port adapter slot 2 with VPI 0 and VCI 6. The PVC uses AAL AAL5-MUX with IP.
Router(config-if)# interface atm 2/0 Router(config-if)# atm pvc 1 0 6 aal5mux ip
See examples of PVC configurations in the "ATM Configuration Examples" section.
This section describes the procedure for mapping a protocol address to a PVC, which is a required task if you are configuring a PVC. The ATM interface supports a static mapping scheme that identifies the ATM addresses of remote hosts or routers. An address is specified as a virtual circuit descriptor (VCD) for a PVC (or an NSAP address for SVC operation).
You enter mapping commands as groups. You first create a map list and then associate it with an interface. Begin the following steps in configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# | To enter these commands, you need to be in configuration mode. |
Step 2 | Router(config)# map-list name | Create a map list by naming it, and enter map-list configuration mode. |
Step 3 | Router(config-map-list)# protocol protocol-address atm vc vcd [broadcast] | Associate a protocol and an address to a specific virtual circuit. |
Step 4 | Router(config-map-list)# protocol protocol-address atm vc vcd [broadcast] | Associate a protocol and address it to a different virtual circuit. |
Step 5 | Router(config)# interface atm port-adapter-slot-number/interface-port- number | Specify an ATM interface (Catalyst RSM/VIP2 in Catalyst 5000 family switch; Cisco 7000 series, Cisco 7100 series, Cisco 7200 series and Cisco uBR7200 series router). |
Router(config)# interface atm interface-processor-slot-number/ port-adapter-slot-number/interface-port | Specify an ATM interface (VIP2 or VIP4 in a Cisco 7000 series or Cisco 7500 series router). | |
Step 6 | Router(config)# atm pvc vcd vpi vci aal-encap [peak average burst] [oam seconds][inarp minutes] | Create a PVC. |
Step 7 | Router(config)# map-group name | Associate a map list to an interface. |
A map list can contain multiple map entries, as Step 3 and Step 4 in the preceding table illustrate. The broadcast keyword specifies that this map entry is to be used when the corresponding protocol sends broadcast packets 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.
If you do specify broadcast but do not set up point-to-multipoint signaling, pseudobroadcasting is enabled. To eliminate pseudobroadcasting and set up point-to-multipoint signaling on virtual circuits configured for broadcasting, refer to the Wide-Area Networking Configuration Guide.
When the map list is complete, you associate it with an ATM interface by using the name argument. (See Step 7.)
You can create multiple map lists and associate them with one ATM interface only. You must create different map lists to associate with different interfaces. See the "ATM Configuration Examples" section.
For further information on configuring the PA-A3 for PVCs, refer to Wide-Area Networking Configuration Guide.
ATM switched virtual circuit (SVC) service operates much like X.25 SVC service, although ATM allows much higher throughput. Virtual circuits are created and released dynamically, providing user bandwidth on demand. This service requires a signaling protocol between the router and the switch.
The ATM signaling software provides a method of dynamically establishing, maintaining, and clearing ATM connections at the User-Network Interface (UNI). The ATM signaling software conforms to ATM Forum UNI 3.0.
In UNI mode, the user is the router, and the network is an ATM switch. This is an important distinction. The Cisco router does not perform ATM-level call routing. Instead, the ATM switch does the ATM call routing, and the router routes packets through the resulting circuit. The router is viewed as the user and the LAN interconnection device at the end of the circuit, and the ATM switch is viewed as the network.
Figure 4-1 illustrates the router position in a basic ATM environment. The router is used primarily to interconnect LANs through an ATM network. Workstation C in the figure is connected directly to the destination ATM switch. You can connect not only routers to ATM switches, but also any computer with an ATM interface that conforms to the ATM Forum UNI specification.
To use SVCs, complete the required tasks in the following sections:
For further information on configuring the PA-A3 port adapter for SVCs, see the Wide-Area Networking Configuration Guide.
Unlike X.25 service, which uses in-band signaling (connection establishment done on the same circuit as data transfer), ATM uses out-of-band signaling. One dedicated PVC exists between the router and the ATM switch, over which all SVC call establishment and call termination requests flow. After the call is established, data transfer occurs over the SVC, from router to router. The signaling that accomplishes the call setup and teardown is called Layer 3 signaling or the Q.2931 protocol.
For out-of-band signaling, a signaling PVC must be configured before any SVCs can be set up. In Figure 4-2, a signaling PVC from the source router to the ATM switch is used to set up two SVCs. This is a fully meshed network; workstations A, B, and C can all communicate with one another.
To configure the signaling PVC for all SVC connections, enter the following command in interface configuration mode:
Router(config-if)# atm pvc vcd vpi vci qsaal
|
Note This signaling PVC can be set up on a major interface only, not on the subinterfaces. |
The VPI and VCI values must be configured consistently with the local switch. The standard value of VPI is 0; the standard value of VCI is 5.
See the "Example of SVCs in a Fully Meshed Network" section for a sample ATM signaling configuration.
Every ATM interface involved with signaling must be configured with a network service access point (NSAP) address. The NSAP address is the ATM address of the interface and must be unique across the network.
You can do one of the following to configure an NSAP address:
When you configure the ATM NSAP address manually, you must enter the entire address in hexadecimal format; that is, each digit entered represents a hexadecimal digit. To represent the complete NSAP address, you must enter 40 hexadecimal digits in the following format:
XX.XXXX.XX.XXXXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XX
|
Note All ATM NSAP addresses must be entered in the dotted hexadecimal format shown, which conforms to the UNI specification. |
Because the interface has no default NSAP address, you must configure the NSAP address for SVCs. To set the ATM interface source NSAP address, enter the following command in interface configuration mode:
Router(config-if)# atm nsap-address nsap-address
The following is an example of an NSAP address assigned to ATM interface 4/0 on a Cisco 7200 series, Cisco uBR7200 series, or Cisco 7100 series router:
interface ATM4/0 atm nsap-address AB.CDEF.01.234567.890A.BCDE.F012.3456.7890.1234.12
You can display the ATM address for the interface by executing the show interfaces atm command.
You can configure the router to get the NSAP address prefix from the switch; however, the switch must be capable of delivering the NSAP address prefix to the router through ILMI, and the router must be configured with a PVC for communication with the switch through ILMI.
To configure the router to get the NSAP prefix from the switch and use locally entered values for the remaining fields of the address, complete the following tasks in interface configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# interface atm slot/port or slot/port-adapter/port | Specify an ATM interface to configure. To use these commands, you need to be in interface configuration mode. (For the appropriate interface address to use for your system, see Table 4-3.) |
Step 2 | Router(config-if)# atm pvc vcd 0 16 ilmi | Configure a PVC for communicating with the switch through ILMI. |
Step 3 | Router(config-if)# atm esi-address esi.selector | Enter the ESI and Selector fields of the NSAP address. |
In the atm esi-address command, the esi argument is 6 hexadecimal bytes long (12 digits), and the selector argument is 1 hexadecimal byte long (2 digits).
In the following example on a Cisco 7200 series router, the ESI and Selector field values are assigned, and the ILMI PVC is set up:
Router(config-if)# interface atm 4/0 Router(config-if)# atm pvc 2 0 16 ilmi Router(config-if)# atm esi-address 345678901234.12
Cisco implements both the ATM Address Resolution Protocol (ARP) server and ATM ARP client functions described in RFC 1577. RFC 1577 models an ATM network as a logical IP subnetwork on a LAN.
The tasks required to configure classical IP and ARP over ATM depend on whether there are SVCs or PVCs are in the environment. For further information, refer to the Wide-Area Networking Configuration Guide.
You can customize the PA-A3. The features you can customize have default values that will probably suit your environment and not need to be changed. However, you might need to enter configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize the PA-A3:
|
Note For the commands that follow, you need to be in interface configuration mode. To enter interface configuration mode, use the interface atm subcommand command, followed by the interface address of the ATM interface you plan to configure. (For information on the interface atm subcommand and the interface address to use, see Table 4-3.) |
Each ATM interface has a default maximum packet size or maximum transmission unit (MTU) size. On the PA-A3, this number defaults to 4470 bytes, the range being 64 through 9188 bytes. To set the maximum MTU size, enter the following command in interface configuration mode:
Router(config-if)# mtu bytes
|
Note This command is documented in the Configuration Fundamentals Command Reference. |
To configure an ATM interface for local loopback (useful for checking that the PA-A3 is working by looping the transmit data back to the receive data), use the following command:
Router(config-if)# loopback diagnostic Router(config-if)# no loopback diagnostic
The no form of the command turns off local loopback.
To configure an ATM interface for external loopback (useful for checking that the PA-A3 is working by looping the receive data back to the transmit data), use the following command:
Router(config-if)# loopback line Router(config-if)# no loopback line
To configure an ATM interface for external loopback at the cell level, use the following command:
Router(config-if)# loopback cell Router(config-if)# no loopback cell
To configure an ATM interface for external loopback at the payload level, use the following command:
Router(config-if)# loopback payload Router(config-if)# no loopback payload
The no form of each command turns off external loopback.
After configuring the new interface, you can display its status. You can also display the current state of the ATM network and connected virtual circuits. To show current virtual circuits and traffic information, enter the following commands in EXEC mode. (For information about EXEC mode, see the "Using the EXEC Command Interpreter" section.)
| Command | Purpose | |
|---|---|---|
Step 1 | Router# show atm interface atm port-adapter-slot-number/0 | Display ATM-specific information about an ATM interface (Catalyst RSM/VIP2 in Catalyst 5000 family switches; Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series router). |
Router# show atm interface atm interface-processor-slot-number/ port-adapter-slot-number/0 | Display ATM-specific information about an ATM interface (VIP2 or VIP4 in a Cisco 7000 series or Cisco 7500 series router).
| |
Step 2 | Router# show atm map | Display the configured list of ATM static maps to remote hosts on an ATM network. |
Step 3 | Router# show atm traffic | Display information about global traffic to and from all ATM networks connected to the router. Display a list of counters of all ATM traffic on this router. |
Step 4 | Router# show atm vc [vcd] | Display ATM virtual circuit information about all PVCs and SVCs (or a specific virtual circuit). |
Step 5 | Router# show sscop1 | Display details for the ATM interface. |
Step 6 | Router# show atm arp-server | Display ATM ARP server table. |
Step 7 | Router# show atm ilmi | Display ATM ILMI information. |
| 1SSCOP=Service-Specific Connection-Oriented Protocol. |
The PA-A3 supports the traffic-shaping parameters defined in Table 4-5. This ensures that generated traffic conforms to the ATM Forum Traffic Management Specification Version 4.0.
| Traffic Parameter | Range | Default |
|---|---|---|
Peak Rate
|
56 kbps to 45 Mbps 56 kbps to 34 Mbps 56 kbps to 155 Mbps |
If the peak rate is not defined, each new VC is set to the maximum physical layer rate. |
Average Rate | 0 < avg < peak | Average = peak rate. |
Maximum Burst Size | 1 to 64,000 | Equal to the PA-A3 MTU size. (User-configurable on ATM interface only.) |
The following sections provide suggested guidelines for troubleshooting the PA-A3. Use the ping command to verify network connectivity, the debug commands to help solve network problems, and the show commands to display the current state of the network.
Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the "Related Documentation" section for detailed command descriptions and examples.
The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout 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 a bad connection.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.
The PA-A3 maintains a count of certain errors and tracks the ATM controller facility performance. In addition to keeping a count of these errors, the PA-A3 also takes snapshots of the last VCI/VPI that caused the error. Each PA-A3 error counter is 16 bits. Errors counted include the following:
The PA-A3 provides port adapter-specific error statistics through the show interfaces atm command.
|
Note For examples of the show interfaces atm command for all supported platforms, see the "Using the show interfaces Command" section. |
The show controllers atm command displays the ATM framing information and ATM facility performance statistics. The statistics report section includes up to 96 15-minute interval reports, as well as the current interval level. Only those intervals with nonzero data are displayed.

The following debug commands help to solve ATM network problems.
Router# debug atm packet
Router# debug atm errors
Router# debug atm events
Router# debug atm oam
You can use ATM show commands to display the current state of the ATM network and the connected VCs.
Router# show atm vc [vcd]
Router# show atm interfaces
Router# show atm traffic
Router# show atm map
The show controllers command (VIP2, VIP4, and Catalyst RSM/VIP2 only) displays the internal status of each system bus, including the interface processor slot location, the hardware version, and the currently running microcode version. The show controllers command also lists each interface (port) on each interface processor, including the logical interface number, interface type, physical (slot/port) address, and hardware (station address) of each interface.
The following example shows information about a PA-A3 installed in a VIP2 in interface processor slot 0:

Use the show interfaces atm command to display statistics for the ATM interface you specify.
|
Note For examples of the show interfaces atm command for all supported platforms, see the "Using the show interfaces Command" section. |
Use the show atm interface atm command to display statistics for the ATM interface you specify by its interface address. Following is an example of the show atm interface atm command on a Cisco 7500 series router:
Router# show atm interface atm 2/0/0 ATM interface ATM2/0/0: AAL enabled: AAL5, Maximum VCs: 4096, Current VCCs: 12 Max. Datagram Size:4528, MIDs/VC: 1024 PLIM Type:DS3 - 45Mbps, Framing is C-bit ADM, DS3 lbo: short, TX clocking: LINE Scrambling: OFF 227585 input, 227585 output, 0 IN fast, 0 OUT fast Config. is ACTIVE
Use the show atm interface atm command to display statistics for the ATM interface you specify by its interface address. Following is an example of the show atm interface atm command on a Catalyst 5000 family switch:
Router# show atm interface atm 0/0 ATM interface ATM0/0: AAL enabled: AAL5, Maximum VCs: 4096, Current VCCs: 12 Max. Datagram Size:4528, MIDs/VC: 1024 PLIM Type:DS3 - 45Mbps, Framing is C-bit ADM, DS3 lbo: short, TX clocking: LINE Scrambling: OFF 227585 input, 227585 output, 0 IN fast, 0 OUT fast Config. is ACTIVE
Use the show sscop command to display SSCOP details for the ATM interface.
Use the show version command to display the configuration of the system hardware (the number of each interface processor type installed), the software version, the names and sources of configuration files, and the boot images.
|
Note For examples of the show version command for all supported platforms, see the "Using the show version or show hardware Commands" section. |
Use the show protocols command to display the global (system-wide) and interface-specific status of any configured Layer 3 protocol.
Use the show running-config command to display the currently running PA-A3 configuration in RAM:
Router# show running-config interface ATM3/0 ip address 10.10.10.2 255.255.255.0 map-group atm1 atm pvc 1 0 1 aal5snap
The following sections contain examples of ATM interface configurations. For detailed configuration examples, refer to the router software publications listed in the "Related Documentation" section.
For examples of emulated LAN configurations, refer to the Wide-Area Networking Configuration Guide.
In the following example, PVC 5 is created on ATM interface 3/0 using LLC/SNAP encapsulation over AAL5. ATM interface 3/0 (IP address 10.0.0.1 255.0.0.0) connects with the ATM interface (IP address 10.0.0.2 255.0.0.0) 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.
interface ATM3/0 ip address 10.0.0.1 255.0.0.0 map-group atm1 atm pvc 5 0 1 aal5snap ! no ip classless ! map-list atm1 ip 10.0.0.2 atm-vc 1 broadcast
The following example shows a typical ATM configuration for a PVC:
interface ATM4/0 ip address 10.0.0.1 255.0.0.0 map-group atm atm pvc 1 1 1 aal5snap atm pvc 2 2 2 aal5snap atm pvc 6 6 6 aal5snap atm pvc 7 7 7 aal5snap clns router iso-igrp comet !

Figure 4-3 shows a fully meshed network. The configurations for Routers A, B, and C follow. In this example, the routers 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. The two map-list statements configured in Router A identify the ATM addresses of Routers B and C. The two map-list statements in Router B identify the ATM addresses of Routers A and C. The two map-list statements in Router C identify the ATM addresses of Routers A and B.

Two routers, each containing a PA-A3, can be connected directly with a standard cable, which allows you to verify the operation of the ATM port or to directly link the routers to build a larger node.
To connect two routers, attach the cable between the ATM port on one and the ATM port on the other.
By default, the PA-A3 "expects" a connected ATM switch to provide transmit clocking. To specify that the PA-A3 generates the transmit clock internally for E3, T3, and SONET physical layer interface module (PLIM) operation, add the atm clock internal command to your configuration.
|
Note For E3, T3 (DS-3), and OC-3c (SONET) interfaces, one of the PA-A3 port adapters in each router must be configured to supply its internal clock to the line. |
The following is an example of configuration file commands for two routers connected through their E3 interface:
First router:
interface ATM3/0 ip address 10.0.0.1 255.0.0.0 no keepalive map-group atm-in atm clock internal atm pvc 1 1 5 aal5snap ! map-list atm-in ip 10.0.0.2 atm-vc 1 broadcast
Second router:
interface ATM3/0 ip address 10.0.0.2 255.0.0.0 no keepalive map-group atm-in atm pvc 1 1 5 aal5snap ! map-list atm-in ip 10.0.0.1 atm-vc 1 broadcast
The boot image contains a subset of the Cisco IOS software. This image is used to perform network booting or to load Cisco IOS images onto the router. This image is also used if the system cannot find a valid system image.
When you upgrade your Cisco IOS software to the minimum required software release (see Table 2-1), we recommend that you also upgrade your boot image. To upgrade your boot image, you can copy the new boot image from a network server to Flash memory on your router. To copy a boot image from a Trivial File Transfer Protocol (TFTP) server to Flash memory, complete the tasks shown in the following table:
| Command | Purpose | |
|---|---|---|
Step 1 | Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# | Specify that the terminal is the source for commands, and enter configuration mode. To enter the commands that follow, you need to be in configuration mode. |
Step 2 | Router(config)# show flash all | (Optional.) If you do not already know it, learn the exact spelling of the system image filename in Flash memory. |
Step 3 | router(config)# copy flash tftp | Make a backup copy of the current boot image. |
Step 4 | router(config)# copy tftp flash | Copy a boot image to Flash memory. |
Step 5 | router(config)# ip-address or name | When prompted, enter the IP address or domain name of the server. |
For further information, such as how to set up the TFTP server, refer to the Configuration Fundamentals Configuration Guide.
