OIR of Cable Interface Linecards

The Cisco uBR7200 series and Cisco uBR10012 universal broadband routers both support OIR of cable interface linecards, but have different requirements. The following sections describe this support for each of the platforms.

OIR of Cable Interface Linecards on the Cisco uBR7200 Series Universal Broadband Routers

Technically, the Cisco uBR7200 series universal broadband routers support true online insertion and removal (OIR), or "hot swapping," of cable interface linecards only when exchanging cable interface linecards of the exact same type (for example, exchanging a Cisco uBR-MC28U card for another Cisco uBR-MC28U card). Under these conditions, no reload of the router is required.

Caution When you OIR different types of cable interface linecards (for example, a Cisco uBR-MC16U card replaced by a Cisco uBR-MC16X card, or Cisco uBR-MC16U card replaced by a Cisco uBR-MC28U card), you not only might have to reconfigure the interfaces, we recommend that you reload the router.

OIR of Cable Interface Linecards on the Cisco uBR10012 Universal Broadband Router

To perform an OIR of cable interface line cards on the Cisco uBR10012 router, do the following steps:

Step 1 From global configuration mode, enter the cr10k card oir-compatibility command for the cable interface line card that you want to OIR, as shown in the following example: 

Router(config)# cr10k card 8/0 oir-compatibility

This command helps preserve the configuration and performs some internal synchronization to make sure that the OIR runs successfully.

Step 2 Save the configuration to ensure the transition, as shown in the following example: 

Router# copy running-config startup-config

Step 3 Turn the power off to the line card using the cable power off command for the slot that is being replaced as shown in the following example: 

Router# cable power off 8/0 

Line Card 8/0 is POWERED OFF


This powers off the line card gracefully.

Step 4 Before removing the card, verify that the proper grounding instructions have been followed for the card.

For more information about preventing electrostatic discharge (ESD) damage, refer to the document at:

http://www.cisco.com/warp/public/109/cable-linecard-handling.pdf

Step 5 Remove the linecard.

Step 6 Replace it with the new linecard in the slot.

Step 7 Enter the cable power on command to power up the linecard, as shown in the following example: 

Router# cable power on 8/0

Step 8 Enter the show interface cable command and verify that the card and line protocol is "up" as shown in the following example: 

Router# show interface cable 8/0/0 

Cable8/0/0 is up, line protocol is up

  Hardware is BCM3210 ASIC, address is 000a.13e8.1ca8 (bia 000a.13e8.1a60)

For information about selecting a new Cisco IOS software release, see How to Choose a Cisco IOS Software Release at the following location:

http://www.cisco.com/warp/public/130/choosing_ios.shtml

For information about upgrading the Cisco universal broadband routers, see the document at the following location:

http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a0080094c07.shtml

For Cisco IOS upgrade ordering instructions, see the document at the following location:

http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/957_pp.htm

To choose a new Cisco IOS software release by comparing feature support or memory requirements, use Cisco Feature Navigator. Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS and Catalyst OS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

To choose a new Cisco IOS software release based on information about defects that affect that software, use Bug Toolkit at the following URL:

http://www.cisco.com/pcgi-bin/Support/Bugtool/launch_bugtool.pl

Upgrading to Cisco IOS Release 12.2(33)SCA on a Cisco uBR7246VXR Universal Broadband Router

A cold start of the router is recommended for an upgrade to Cisco IOS Release 12.2(33)SCA from a different release train on a Cisco uBR7246VXR router, such as Cisco IOS Release12.3(23)BC or other BC releases.

Upgrading to Cisco IOS Release 12.2(33)SCA on a Cisco uBR10012 Universal Broadband Router

A cold start of the router is recommended for an upgrade to Cisco IOS Release 12.2(33)SCA on a Cisco uBR10012 Universal Broadband Router from a different release train, such as Cisco IOS Release 12.3(23)BC or other BC releases.

If you are supporting ESR-PRE1 or earlier processors, it is also required to upgrade to ESR-PRE2 processors to support Cisco IOS Release 12.2(33)SCA.

Upgrading from ESR-PRE1 to ESR-PRE2 Processors

Upgrading a system that currently uses an ESR-PRE1 (or earlier processor) requires a hardware upgrade to an ESR-PRE2 to run Cisco IOS Release 12.2(33)SCA. For hardware installation instructions, see the Cisco Performance Routing Engine (ESR-PRE2) Upgrade Installation document at the following URL:

http://www.cisco.com/en/US/docs/interfaces_modules/cable/performance_routing_engine/quick/start/pre2_qsg.html

Upgrading from a 12.3BC or Earlier Cisco IOS Software Release

To upgrade from a 12.3BC or earlier Cisco IOS software release, perform the following steps for an ESR-PRE2 cold start.

This procedure assumes the following configuration:

•Cisco 10012 series chassis with two installed ESR-PRE2 processors

•A non-upgrade-enabled image such as Cisco IOS Release 12.3BC or earlier on the PRE2s

Note The router will not be available for user traffic during Step 7 of the software upgrade, and traffic cannot resume until the upgrade is complete.

To perform the upgrade, follow these steps:

Step 1 Load the appropriate 12.2SC image from the TFTP server into bootflash on both ESR-PRE2s.

Step 2 If the startup configuration is not up to date, save the running configuration using the write-memory command.

Step 3 Copy the startup configuration from the active ESR-PRE2 to a disk or TFTP server to save it for possible rollback.

Step 4 At the console, use the boot system bootflash:image_name command to edit your boot system variable to point to the 12.2SC image in bootflash. Save the running configuration using the write memory command.

Use the show bootvar command to verify that the boot system variable has been altered appropriately on both the active and standby ESR-PRE2s.

If you do not want to make further changes to the startup configuration for the new command set offered by release 12.2SC, skip to Step 7.

Note In some older releases, the configuration does not explicitly specify the redundancy mode. If your current configuration is one of these, and you want RPR+ operation with release 12.2SC, you must add the line mode rpr-plus after the line that specifies redundancy in the configuration on the TFTP server. Release 12.2SC defaults to SSO mode unless it is explicitly configured for RPR+.

Step 5 Your startup configuration now reflects the altered boot system image. Copy it to the TFTP server and make any other needed edits. Then copy the altered configuration from the server to the startup configuration on the active and standby ESR-PRE2s using the copy tftp startup and copy tftp stby-nvram:startup-config commands. Verify that the startup configuration has been copied to both the active and the standby NVRAM using the dir command and comparing file size.

Step 6 Verify again that the boot image and config-register are set appropriately using the show bootvar command.

Step 7 On the active ESR-PRE2, enter the reload command and type no if you are asked to save the running configuration.

•If the system is configured for autoboot, it will autoboot the new 12.2SC image on both ESR-PRE2s.

•If the system is not configured for autoboot, both ESR-PRE2s will come up in ROM monitor after reloading. Boot the 12.2SC image in bootflash from the ROM monitor prompt on each ESR-PRE2.

At this point, the system should be operating as a dual-PRE redundant 12.2(28)SB system in the configured mode (either SSO or RPR+), running the properly modified startup configuration. You can verify the redundancy status using the show redundancy or show redundancy state command.

Step 8 Enter the write memory command from the active console to bring the startup configuration up to date on the active and standby ESR-PRE2s.

Rollback Procedure

To roll back to the original release:

Step 1 Copy the original startup configuration from the TFTP server to the startup configuration on the active and standby ESR-PRE2s using the copy tftp startup and copy tftp stby-nvram:startup-config commands. (This is the configuration file you copied in Step 3 of the upgrade procedure.)

Step 2 Use the show bootvar command to verify that the boot system variable now points to the old image and the config-register is set appropriately.

Step 3 Reload the active ESR-PRE2 using the reload command.

•If autoboot is set, the system should come up in the configured redundant mode (for older releases that support redundancy).

•If autoboot is not set, the system will come up to ROM monitor. From the ROM monitor prompt, boot the proper image from the bootflash on each ESR-PRE2.

You have now reverted to the original system configuration.

Feature Support

Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.

Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
