Initially Configuring the ATM Switch Router

Initially Configuring the ATM Switch Router

This chapter discusses specific steps used to initially configure the ATM switch router.

Note   This chapter provides advanced configuration instructions for the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For conceptual and background information, refer to the Guide to ATM Technology . For complete descriptions of the commands mentioned in this chapter, refer to the ATM  Switch Router Command Reference publication.

This chapter includes the following sections:

Methods for Configuring the ATM Switch Router

The ATM switch router defaults to a working configuration suitable for most networks. However, you might need to customize the configuration for your network.

Note   If your Telnet station or SNMP network management workstation is on a different network from the switch, you must add a static routing table entry to the routing table. See the "Configuring Static Routes" section.

Terminal Line Configuration (Catalyst 8540 MSR)

The ATM switch router has a console terminal line that might require configuration. For line configuration, you must first set up the line for the terminal or the asynchronous device attached to it. For a complete description of configuration tasks and commands used to set up your terminal line and settings, refer to the Configuration Fundamentals Configuration Guide and Dial Solutions Configuration Guide.

You can connect a modem to the console port. The following settings on the modem are required:

You can configure your modem by setting the DIP switches on the modem or by connecting the modem to terminal equipment. Refer to the user manual provided with your modem for the correct configuration information.

Note   Because there are no hardware flow control signals available on the console port, the console port terminal characteristics should match the modem settings.

Terminal Line Configuration (Catalyst 8510 MSR and LightStream 1010)

The ATM switch has two types of terminal lines: a console line and an auxiliary line. For line configuration, you must first set up the lines for the terminals or other asynchronous devices attached to them. For a complete description of configuration tasks and commands used to set up your lines, modems, and terminal settings, refer to the Configuration Fundamentals Configuration Guide and Dial Solutions Configuration Guide.

Configuration Prerequisites

Consider the following information you might need before you configure your ATM switch router:

Configuring the BOOTP Server

The BOOTP protocol automatically assigns an Ethernet IP address by adding the MAC and IP addresses of the Ethernet port to the BOOTP server configuration file. When the switch boots, it automatically retrieves the IP address from the BOOTP server.

The switch performs a BOOTP request only if the current IP address is set to 0.0.0.0. (This is the default for a new switch or a switch that has had its startup-config file cleared using the erase command.)

To allow your ATM switch router to retrieve its IP address from a BOOTP server, you must first determine the MAC address of the switch and add that MAC address to the BOOTP configuration file on the BOOTP server. The following steps provide an example of creating a BOOTP server configuration file:

Command Purpose

Step 1 

—

Installs the BOOTP server code on the workstation, if it is not already installed.

Step 2 

—

Determines the MAC address from the label on the chassis.

Step 3 

—

Adds an entry in the BOOTP configuration file (usually /usr/etc/bootptab) for each switch. Press Return after each entry to create a blank line between each entry. See the example BOOTP configuration file that follows.

Step 4 

Switch# reload

Restarts the ATM switch router to automatically request the IP address from the BOOTP server.

Example

The following example BOOTP configuration file shows the added entry:

# /etc/bootptab: database for bootp server (/etc/bootpd)
#
# Blank lines and lines beginning with '#' are ignored.
#
# Legend:
#
#       first field -- hostname

Configuring the ATM Address

The ATM switch router ships with a preconfigured ATM address. The Integrated Local Management Interface (ILMI) protocol uses the first 13 bytes of this address as the switch prefix that it registers with end systems. Autoconfiguration also allows the ATM switch router to establish itself as a node in a single-level Private Network-Network Interface (PNNI) routing domain.

Note   If you chose to manually change any ATM address, it is important to maintain the uniqueness of the address across large networks. Refer to the Guide to ATM Technology for PNNI address considerations and for information on obtaining registered ATM addresses.

For a description of the autoconfigured ATM address and considerations when assigning a new address, refer to the Guide to ATM Technology.

Manually Setting the ATM Address

To configure a new ATM address that replaces the previous ATM address when running IISP software only, see the "Configuring the ATM Address" section.

To configure a new ATM address that replaces the previous ATM address and generates a new PNNI node ID and peer group ID, see the "Configuring an ATM Address and PNNI Node Level" section.

Modifying the Physical Layer Configuration of an ATM Interface

Each of the ATM switch router's physical interfaces has a default configuration, listed in "Configuring Interfaces." You can accept the defaults, or you can override them by reconfiguring the physical interface.

The following example describes modifying an OC-3c interface from the default settings to the following:

To change the configuration of the example interface, perform the following steps, beginning in global configuration mode:

Command Purpose

Step 1 

Switch(config)# interface atm card/subcard/port

Switch(config-if)#

Selects the physical interface to be configured.

Step 2 

Switch(config-if)# no scrambling cell-payload

Disables cell-payload scrambling.

Step 3 

Switch(config-if)# no scrambling sts-stream

Disables STS-stream scrambling.

Step 4 

Switch(config-if)# sonet stm-1

Configures SONET mode as SDH/STM-1.

Example

The following example shows how to disable cell-payload scrambling and STS-stream scrambling and changes the SONET mode of operation to Synchronous Digital Hierarchy/Synchronous Transfer Module 1 (SDH/STM-1) of OC-3c physical interface ATM 0/0/0:

Switch(config)# interface atm 0/0/0
Switch(config-if)# no scrambling cell-payload
Switch(config-if)# no scrambling sts-stream
Switch(config-if)# sonet stm-1

To change any of the other physical interface default configurations, refer to the commands in the ATM  Switch Router Command Reference publication.

To display the physical interface configuration, use the following privileged EXEC commands:

Command

Purpose

 show controllers atm card/subcard/port


 Shows the physical layer configuration. 


 more system:running-config


 Shows the physical layer scrambling configuration.

Examples

The following example demonstrates using the show controllers command to display the OC-3c physical interface configuration after modification of the defaults:

Switch# show controllers atm 0/0/0
IF Name: ATM0/0/0    Chip Base Address: A8808000

Configuring the IP Interface

IP addresses can be configured on the multiservice route processor interfaces. Each IP address is configured for one of the following types of connections:

Note   These IP connections are used only for network management.

To configure the switch to communicate via the Ethernet interface, provide the IP address and subnet mask bits for the interface.

This section includes the following:

Configuring IP Address and Subnet Mask Bits

Define subnet mask bits as a decimal number between 0 and 22 for Class A addresses, between 0 and 14 for Class B addresses, or between 0 and 6 for Class C addresses. Do not specify 1 as the number of bits for the subnet field. That specification is reserved by Internet conventions.

To configure the IP address, perform the following steps, beginning in global configuration mode:

Command Purpose

Step 1 

Switch(config)# interface ethernet 0

Switch(config-if)#

Selects the interface to be configured.

Step 2 

Switch(config-if)# ip address ip-address mask

Configures the IP and subnetwork address.

Note   Since release 12.0(1a)W5(5b) of the ATM switch software, addressing the interface on the processor (CPU) has changed. The ATM interface is now called atm 0, and the Ethernet interface is now called ethernet 0. The old formats (atm 2/0/0 and ethernet 2/0/0) are still supported.
Example

The following example shows how to configure interface ethernet 0 with IP address 172.20.40.93 and subnetwork mask 255.255.255.0:

Switch(config)# interface ethernet 0
Switch(config-if)# ip address 172.20.40.93 255.255.255.0

Displaying the IP Address

To display the IP address configuration, use the following privileged EXEC commands:

Command

Purpose

 show interfaces ethernet 0


 Displays the Ethernet interface IP address.


 more system:running-config


 Shows the physical layer scrambling configuration.

Examples

The following example shows how to use the show interfaces command to display the IP address of interface ethernet 0:

Switch# show interfaces ethernet 0
Ethernet0 is up, line protocol is up
  Hardware is SonicT, address is 0040.0b0a.1080 (bia 0040.0b0a.1080)
  Internet address is 172.20.40.93/24
  <information deleted>

The following example uses the more system:running-config command to display the IP address of interface ethernet 0:

Switch# more system:running-config
!
version XX.X
<information deleted>
!
interface Ethernet0
 ip address 172.20.40.93 255.255.255.0
!
<information deleted>

Testing the Ethernet Connection

After you have configured the IP address(es) for the Ethernet interface, test for connectivity between the switch and a host. The host can reside anywhere in your network. To test for Ethernet connectivity, use the following EXEC command:

Command

Purpose

 ping ip ip-address


 Tests the configuration using the ping command. The ping command sends an echo request to the host specified in the command line.

The following example show how to test the Ethernet connectivity from the switch to a workstation with an IP address of 172.20.40.201:

Switch# ping ip 172.20.40.201
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.40.201, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/202/1000 ms

Configuring Network Clocking

This section describes network clocking configuration of the ATM switch router. Properly synchronized network clocking is important in the transmission of constant bit rate (CBR) and variable bit rate real time (VBR-RT) data. For an overview of network clocking and network clock configuration issues, refer to the chapter "Network Clock Synchronization" in the Guide to ATM Technology .

This section includes the following:

Network Clocking Features

Different types of network clock sources are available on the ATM switch router, both internal and external. Table 3-1 provides a summary of network clocking features.

Configuring Network Clock Sources and Priorities (Catalyst 8540 MSR)

To configure the network clocking priorities and sources, use the following command in global configuration mode:

Command

Purpose

 network-clock-select {priority {{atm | cbr} card/subcard/port} | bits {0 | 1} | system} |
bits {e1 | t1} | revertive


 Configures the network clock priority.

Note   Specifying the keyword system with the network-clock-select command selects the route processor reference clock (a stratum 4 clock source) or the network clock module (a stratum 3 clock source), if present.

Systems equipped with the network clock module can derive clocking from a Building Integrated Timing Supply (BITS) source. To specify the line type attached to the BITS ports on the network clock module and to assign a priority to a port, use the following commands in global configuration mode:

Command

Purpose

 network-clock-select bits {t1 | e1}


 Selects the line type. This command applies to both BITS ports.


 network-clock-select priority bits {0 | 1}


 Selects the priority for a BITS port.

Examples

The following example shows how to configure the network clock priorities:

Switch(config)# network-clock-select 1 atm 0/0/0
Switch(config)# network-clock-select 2 atm 0/0/3
Note   This configuration assumes that a full-width module, such as the 4-port OC-12c module, is being used to derive clocking. If port adapters inserted into carrier modules are used, the priority 1 and 2 source ports must be on different port adapters.

The following example shows how to configure the network clock to revert to the highest priority clock source after a failure and takeover by the source with the next lowest priority.

Switch(config)# network-clock-select revertive

Configuring Network Clock Sources and Priorities (Catalyst 8510 MSR and LightStream 1010)

To configure the network clocking priorities and sources, use the following command in global configuration mode:

Command

Purpose

 network-clock-select {priority {{atm | cbr} card/subcard/port} | system} | revertive


 Configures the network clock priority.

Note   Specifying the keyword system with the network-clock-select command selects the processor card reference clock (a stratum 4 clock source).
Examples

The following example shows how to configure the network clock priorities:

Switch(config)# network-clock-select 1 atm 0/0/0
Switch(config)# network-clock-select 2 atm 0/0/3

The following example shows how to configure the network clock to revert to the highest priority clock source after a failure and takeover by the source with the next lowest priority.

Switch(config)# network-clock-select revertive

Configuring the Transmit Clocking Source

To configure where each interface receives its transmit clocking, perform the following steps, beginning in global configuration mode:

Command Purpose

Step 1 

Switch(config)# interface atm card/subcard/port

Switch(config-if)#

Selects the interface to be configured.

Step 2 

Switch(config-if)# clock source {free-running | loop-timed | network-derived}

Configures the interface clock source.

Caution If the Network Clock Distribution Protocol (NCDP) is running on an interface, you should not override that port's clock source by configuring it to free-running or loop-timed. Doing so could cause synchronization problems, particularly in the case of loop-timed, which could cause a clocking loop to be formed on a link. See the "Configuring Network Clocking with NCDP" section.
Example

The following example configures ATM interface 3/0/0 to receive its transmit clocking from a network-derived source:

Switch(config)# interface atm 3/0/0
Switch(config-if)# clock source network-derived

Displaying the Network Clocking Configuration

To show the switch's network clocking configuration, use the following privileged EXEC commands:

Command

Purpose

 show network-clocks


 Shows the network clocking configuration. 


 more system:running-config


 Shows the interface clock source configuration. 


 show controllers [atm card/subcard/port]


 Shows the interface controller status.

Examples

The following example shows the configured network clock sources on a Catalyst 8510 MSR or LightStream 1010:

Switch# show network-clocks
clock configuration is NON-Revertive
Priority 1 clock source: ATM1/0/0
Priority 2 clock source: ATM1/1/0
Priority 3 clock source: No clock
Priority 4 clock source: No clock
Priority 5 clock source: System clock
Current clock source:System clock, priority:5
Note   A source listed as "No clock" indicates that no clock source configured at that priority.

The following example shows the switch clock source configuration with the network clock module installed:

Switch# show network-clocks
Network clocking information:

Configuring Network Clocking with NCDP

The Network Clock Distribution Protocol (NCDP) provides a means by which a network can synchronize automatically to a primary reference source (PRS). To do so, NCDP constructs and maintains a spanning network clock distribution tree. This tree structure is superimposed on the network nodes by the software, resulting in an efficient, synchronized network suitable for transport of traffic with inherent synchronization requirements, such as voice and video.

The following sections provide instructions for configuring NCDP. For a description of how NCDP works, refer to the Guide to ATM Technology .

NCDP Network Example

Figure 3-1 shows a network of six ATM switch routers with clocking derived from a stratum 3 PRS. Node A is configured to receive priority 1 clocking on two of its ports, while node B is configured to receive priority 2 clocking on one of its ports.


Figure 3-1: Network Configuration for NCDP


Enabling NCDP

To enable NCDP, use the following global configuration command for each node that you want to configure for NCDP:

Command

Purpose

 ncdp


 Enables NCDP.

Configuring Network Clock Sources and Priorities

You must specify the clocking sources, their priorities, and associated stratums used by NCDP in constructing the clock distribution tree. To do so, use the following command in global configuration mode:

Command

Purpose

 ncdp source priority {{atm | cbr} card/subcard/port stratum | bits1 {0 | 1} stratum | system}


 Specifies a priority and source (stratum level or system) for this interface.
1Allows you to specify a Building Integrated Timing Supply (BITS) source. This option is available only on the Catalyst 8540 MSR equipped with the network clock module.

If you do not configure a clock source, NCDP advertises its default source of network clock, which is its local oscillator; if no nodes in the network have a clock source configured, the tree is built so that it is rooted at the switch having the highest stratum oscillator (lowest numerical value) and lowest ATM address.

Example

The following example demonstrates configuring the network clock source, priority, and stratum on node A in Figure 3-1.

Switch(config)# ncdp source 1 atm 1/0/0 3
Switch(config)# ncdp source 1 atm 3/0/0 3

Configuring Optional NCDP Global Parameters

Optional NCDP parameters you can configure at the global level include the maximum number of hops between any two nodes, revertive behavior, and the values of the NCDP timers. To change any of these parameters from their defaults, use the following commands in global configuration mode:

Command

Purpose

 ncdp max-diameter hops


 Specifies the maximum network diameter for the protocol. The default maximum network diameter is20.


 ncdp revertive


 Specifies the NCDP as revertive.


 ncdp timers {hello | hold} time-in-msec jitter-percent


 Specifies the values to be used by the NCDP timers.

When you specify a maximum diameter, you constrain the diameter of the spanning tree by specifying the maximum number of hops between any two nodes that participate in the protocol. Each node must be configured with the same maximum network diameter value for NCDP to operate correctly.

When you configure the NCDP as revertive, a clock source that is selected and then fails is selected again once it has become operational for a period of time. On the Catalyst 8510 MSR and LightStream 1010 platforms, if NCDP is configured to be revertive, a failed clocking source node after a switchover is restored to use after it has been functioning correctly for at least 1 minute. On the Catalyst 8540 MSR the failed source is restored after about 25 seconds. The network clock is, by default, configured as nonrevertive. Nonrevertive prevents a failed source from being selected again.

Example

The following example shows setting the maximum number of hops to 11 and enabling revertive behavior:

Switch(config)# ncdp max-diameter 11
Switch(config)# ncdp revertive

Configuring Optional NCDP Per-Interface Parameters

On a per-interface basis, you can enable or disable NCDP, specify the cost metric associated with the port, and change the control virtual circuit used to transport protocol messages between adjacent protocol entities. To change any of these parameters from their defaults, use the following commands in interface configuration mode:

Command

Purpose

 ncdp admin-weight weight


 Specifies the cost metric associated with the given port.


 ncdp control-vc vpi vci


 Specifies the VPI/VCI values to use for control VCs. The default is 0, 34.


 no ncdp


 Disables NCDP on the interface.

Example

The following example demonstrates setting the administrative weight on an interface:

Switch(config)# interface atm 0/0/0
Switch(config-if)# ncdp admin-weight 75

Displaying the NCDP Configuration

To display the NCDP configuration, use the following EXEC commands:

Command

Purpose

 show ncdp path root


 Displays the NCDP clock path from the switch to the root source.


 show ncdp ports


 Displays NCDP port information.


 show ncdp sources


 Displays NCDP clock sources configured on the switch.


 show ncdp status


 Displays NCDP status.


 show ncdp timers


 Displays NCDP timer information.

Network Clock Services for CES Operations and CBR Traffic

Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation layer 1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video transmissions, which have particular clocking requirements. For details, refer to "Configuring Circuit Emulation Services."

Configuring Network Routing

The default software image for the ATM switch router contains the Private Network-Network Interface (PNNI) routing protocol. The PNNI protocol provides the route dissemination mechanism for complete plug-and-play capability. The following section, "Configuring ATM Static Routes for IISP or PNNI," describes modifications that can be made to the default PNNI or Interim-Interswitch Signalling Protocol (IISP) routing configurations.

For routing protocol configuration information, refer to "Configuring ILMI,"and "Configuring ATM Routing and PNNI."

Configuring ATM Static Routes for IISP or PNNI

Static route configuration allows ATM call setup requests to be forwarded on a specific interface if the addresses match a configured address prefix. To configure a static route, use the following command in global configuration mode:

Command

Purpose

 atm route addr-prefx atm card/subcard/port


 Specifies a static route to a reachable address prefix.

Note   An interface must be User-Network Interface (UNI) or Interim Interswitch Signalling Protocol (IISP) to be configured with static route. Static routes configured as PNNI interfaces default as down.

The following example shows how to use the atm route command to configure the 13-byte peer group prefix = 47.0091.8100.567.0000.0ca7.ce01 at interface ATM 3/0/0:

Switch(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0
Switch(config)#

Configuring System Information

Although not required, the system clock and hostname should be set as part of the initial system configuration. To set these system parameters, perform the following steps, beginning in privileged EXEC mode:

Command Purpose

Step 1 

Switch# clock set hh:mm:ss day month year

Sets the system clock.

Step 2 

Switch# configure terminal

Switch(config)#

Enters global configuration mode from the terminal.

Step 3 

Switch(config)# hostname name

Sets the system name.

Examples

The following example shows how to configure the time, date, and month using the clock set command, enter global configuration mode, and assign a hostname.

Switch# clock set 15:01:00 17 October 1999
Switch# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)# hostname Publications
Publications#

The following example shows how to confirm the clock setting using the show clock command:

Publications# show clock
*15:03:12.015 UTC Fri Oct 17 1999

Configuring Redundancy and Enhanced High System Availability (Catalyst 8540 MSR)

The ATM switch router supports redundant CPU operation with dual route processors. In addition, Enhanced High System Availability (EHSA) is provided in the switching fabric when three switch processors are installed in the chassis. These features and their configuration are described in the following sections:

Route Processor Redundant Operation (Catalyst 8540 MSR)

The ATM switch router supports fault tolerance by allowing a secondary route processor to take over if the primary fails. This secondary, or redundant, route processor runs in standby mode. In standby mode, the secondary route processor is partially booted with the Cisco IOS software; however, no configuration is loaded.

At the time of a switchover, the secondary route processor takes over as primary and loads the configuration as follows:

The former primary then becomes the secondary route processor.

Note   If the secondary route processor is unavailable, a major alarm is reported. Use the show facility-alarm status command to display the redundancy alarm status.

When the ATM switch router is powered on, the two route processors go through an arbitration to determine which is the primary route processor and which is the secondary. The following rules apply during arbitration:

During normal operation, the primary route processor is booted completely. The secondary CPU is partially up, meaning it stops short of parsing the configuration. From this point, the primary and secondary processors communicate periodically to synchronize any system configuration changes.

The following situations can cause a switchover of the primary route processor:

When a switchover occurs, permanent virtual channels (PVCs) are preserved; switched virtual channels (SVCs) and Integrated Local Management Interface (ILMI) address states are lost, and then restored after they are dynamically redetermined.

Configuring Route Processor Redundancy (Catalyst 8540 MSR)

For redundant operation, the following requirements must be met:

If these requirements are met, the ATM switch router runs in redundant mode by default. The tasks described in the following sections are optional and used only to change nondefault values.

Forcing a Route Processor Switchover (Catalyst 8540 MSR)

You can manually force the secondary route processor to take over as primary. To do so, use the following privileged EXEC command:

Command

Purpose

 redundancy force-failover main-cpu


 Forces a route processor switchover.

As long as you have not changed the default configuration register setting, which is set to autoboot by default, the secondary route processor (formerly the primary) completes the boot process from standby mode.

If you have changed the default configuration register value, you can change it back to autoboot, and ensure that the correct system image is used at startup, by performing the following steps, beginning in global configuration mode:

Command Purpose

Step 1 

Switch(config)# config-register 0x2102

Sets the config register for autoboot.

Step 2 

Switch(config)# boot system {[device:]filename [hostname | ip-address] | flash [device:][filename] | mop filename [type] [card/subcard/port] | rcp filename [ip-address] | rom | tftp filename [hostname | ip-address]}

Specifies the system image file to load at startup.

Step 3 

Switch(config)# end

Switch#

Returns to privileged EXEC mode.

Step 4 

Switch# copy running-config startup-config

Saves the configuration to NVRAM.

Note   If the secondary route processor remains in ROM monitor mode, you can manually boot the processor from either the bootflash or Flash PC card.
Caution If no system image is specified in the startup configuration, the ROM monitor automatically boots the first system image on the Flash PC card in slot0. If there is no system image on the Flash PC card, or the Flash PC card is not available, the ROM monitor boots the first system image in bootflash. If there is no system image in bootflash, the switch remains in ROM monitor mode.

Displaying the Configuration Register Value

To display the configuration register value, use the following privileged EXEC command:

Command

Purpose

 show version


 Displays the configuration register value.

The following example shows the configuration register value:

Switch# show version

Synchronizing the Configurations (Catalyst 8540 MSR)

During normal operation, the startup and running configurations are synchronized by default between the two route processors. In the event of a switchover, the new primary route processor uses the current configuration. Configurations synchronize either immediately from the command line or during route processor switchover.

Immediately Synchronizing Route Processor Configurations (Catalyst 8540 MSR)

To immediately synchronize the configurations used by the two route processors, use the following privileged EXEC command on the primary route processor:

Command

Purpose

 redundancy manual-sync {startup-config | running-config | both}


 Immediately synchronizes the configuration.

Example

In the following example, both the startup and running configurations are synchronized immediately:

Switch# redundancy manual-sync both

Synchronizing the Configurations During Switchover (Catalyst 8540 MSR)

To manually synchronize the configurations used by the two route processors during a switchover, perform the following steps on the primary route processor, beginning in global configuration mode:

Command Purpose

Step 1 

Switch(config)# redundancy

Switch(config-r)#

Enters redundancy configuration mode.

Step 2 

Switch(config-r)# main-cpu

Switch(config-r-mc)#

Enters main-cpu configuration submode.

Step 3 

Switch(config-r-mc)# sync config {startup | running | both}1

Synchronizes either or both configurations during switchover or writing the files to NVRAM.

Step 4 

Switch(config-r-mc)# end

Switch#

Returns to privileged EXEC mode.

Step 5 

Switch# copy running-config startup-config

Forces a manual synchronization of the configuration files in NVRAM.

Note   This step is unnecessary to synchronize the running configuration file in DRAM.

1Alternatively, you can force an immediate synchronization by entering the redundancy manual-sync command in privileged EXEC mode.

Example

In the following example, both the startup and running configurations are synchronized:

Switch(config)# redundancy
Switch(config-r)# main-cpu
Switch(config-r-mc)# sync config both
Switch(config-r-mc)# end
Switch# copy running-config startup-config

Displaying the Route Processor Redundancy Configuration (Catalyst 8540 MSR)

To display the route processor redundancy configuration, use the following privileged EXEC command:

Command

Purpose

 show redundancy

In the following example shows the route processor redundancy configuration:

Switch# show redundancy

Preparing a Route Processor for Removal (Catalyst 8540 MSR)

Before removing a route processor that is running the IOS in secondary mode, it is necessary to change it to ROM monitor mode. You could use the reload command to force the route processor to ROM monitor mode but the automatic reboot would occur and you would interrupt switch traffic.

Caution  If you fail to prepare the secondary route processor for removal, the traffic through the switch could be interrupted.

To change the secondary route processor to ROM monitor mode and eliminate the automatic reboot prior to removal, perform the following task beginning in privileged EXEC mode:

Command Purpose

Step 1 

Switch# copy running-config startup-config

Forces a manual synchronization of the configuration files in NVRAM.

Step 2 

Switch)# redundancy prepare-for-cpu-removal

Changes the current route processor to ROM monitor mode prior to removal.

Example

The following example shows how to change the current route processor to ROM monitor mode prior to removal:

Switch# copy running-config startup-config

Configuring Switch Fabric Enhanced High System Availability Operation (Catalyst 8540 MSR)

Slots 5, 6, and 7 in the ATM switch router chassis can accommodate either two or three switch processor cards, with a switching capacity of 10 Gbps each. The possible configurations are as follows:

When three switch processors are installed, two are active at any time, while the third runs in standby mode. By default, switch processors 5 and 7 are active and switch processor 6 is the standby. To force the standby switch processor to become active, use the redundancy preferred-switch-card-slots command.

Caution Do not hot swap an active switch processor module before putting it in standby mode. Removing an active switch processor breaks active connections and stops the flow of traffic through the switch. Put an active switch in standby mode using the redundancy preferred-switch-card-slots command before removing it from the chassis.

When a switchover to the standby switch processor occurs, the system resets and all connections are lost. When the system comes up again, all PVCs and SVCs are reestablished automatically.

Configuring Preferred Switching Processors (Catalyst 8540 MSR)

To configure which two of the three switch processors are active and which runs in standby mode, use the following privileged EXEC command on the primary route processor:

Command

Purpose

 redundancy preferred-switch-card-slots
{5 | 6 | 7} {5 | 6 | 7}


 Configures the active and standby switch processors.

Example

In the following example, the preferred switch processors are configured to be in slots 5 and 7 with the slot 6 switch processor running in standby mode:

Switch# redundancy preferred-switch-card-slots 5 7
The preferred switch cards selected are already active
Note   The preferred switch card slot configuration reverts to the default configuration when the switch is power cycled.

Displaying the Preferred Switch Processor Redundancy Configuration (Catalyst 8540 MSR)

To display the preferred switch processor redundancy configuration, use the following privileged EXEC command:

Command

Purpose

 show preferred-switch-card-slots


 Displays the redundancy configuration.

The following example shows the preferred switch processor redundancy configuration:

Switch# show preferred-switch-card-slots
The currently preferred switch card slots are slot: 5 and slot: 7
The currently active switch card slots are slot: 5 and slot: 7

Displaying the Switch Processor EHSA Configuration (Catalyst 8540 MSR)

To display the switch processor EHSA configuration, use the following privileged EXEC command:

Command

Purpose

Configuring SNMP and RMON

SNMP is an application-layer protocol that allows an SNMP manager, such a network management system (NMS), and an SNMP agent on the managed device to communicate. You can configure SNMPv1, SNMPv2, or both, on the ATM switch router. Remote Monitoring (RMON) allows you to see the activity on network nodes. By using RMON in conjunction with the SNMP agent on the ATM switch router, you can monitor traffic through network devices, segment traffic that is not destined for the ATM switch router, and create alarms and events for proactive traffic management.

For detailed instructions on SNMP and general RMON configuration, refer to the Configuration Fundamentals Configuration Guide. For instructions on configuring ATM RMON, refer to "Configuring ATM Accounting and ATM RMON."

Storing the Configuration

When autoconfiguration and any manual configurations are complete, you should copy the configuration into nonvolatile random-access memory (NVRAM). If you should power off your ATM switch router prior to saving the configuration in NVRAM, all manual configuration changes are lost.

To save the running configuration to NVRAM, use the following command in privileged EXEC mode:

Command

Purpose

 copy system:running-config nvram:startup-config


 Copies the running configuration in system memory to the startup configuration stored in NVRAM.

Testing the Configuration

The following sections describe tasks you can perform to confirm the hardware, software, and interface configuration:

Note   The following examples differ depending on whether the switch processor feature card is present. (Catalyst 8540 MSR)
Note   The following examples differ depending on the feature card installed on the processor. (Catalyst 8510 MSR and LightStream 1010)

Testing the Ethernet Connection

After you have configured the IP address(es) for the Ethernet interface, test for connectivity between the switch and a host. The host can reside anywhere in your network. To test for Ethernet connectivity, use the following user EXEC command:

Command

Purpose

 ping ip ip-address


 Tests the configuration using the ping command. The ping command sends an echo request to the host specified in the command .

For example, to test Ethernet connectivity from the switch to a workstation with an IP address of 172.20.40.201, enter the command ping ip 172.20.40.201. If the switch receives a response, the following message displays:

Switch# ping ip 172.20.40.201
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.20.40.201, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/202/1000 ms

Confirming the ATM Connections

Use the ping atm interface command to confirm that the ATM connections are configured correctly:

Switch# ping atm interface atm 3/0/0 0 5 seg-loopback
 
Type escape sequence to abort.
Sending Seg-Loopback 5, 53-byte OAM Echoes to a neighbour,timeout is 5 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
