    Background Information

    Introduction

    This document explains the step-by-step procedures to upgrade the software images on Catalyst 6000/6500 Series Switches with redundant Supervisor Engines that run in Hybrid mode (Cisco Catalyst Operating System (CatOS) on Supervisor Engine, and Cisco IOS on Multilayer Switch Feature Card (MSFC)) or Native mode (Cisco IOS System Software on Supervisor Engine and MSFC). Refer to Convert CatOS to Cisco IOS for Catalyst 6500/6000 Switches for more information on the differences between CatOS and Cisco IOS System Software.

    Note: This document also applies when you upgrade the Cisco IOS native image in a VSS environment.

    The software image upgrade is necessary when:

    • You want to implement new features in your network that are available in the new software release.

    • You want to install a new line card that is not supported by the current software version that you run on the switch.

    • A known bug affects your switch, and that bug is resolved in the next software release.

    Supervisor Redundancy

    Catalyst 6500 Series Switches allow a redundant Supervisor Engine to take over if the primary Supervisor Engine fails in order to support fault resistance. Redundant Supervisor Engines must be of the same type with the same model feature card to support redundancy. When you install two Supervisor Engines, the first one to come online becomes the active module. The second Supervisor Engine goes into standby mode. All administrative and network management functions, such as Simple Network Management Protocol (SNMP), command-line interface (CLI) console, Telnet, Spanning Tree Protocol (STP), Cisco Discovery Protocol (CDP), and VLAN Trunk Protocol (VTP) are processed on the active Supervisor Engine. On the standby Supervisor Engine, the console port is inactive. Redundant Supervisor Engines are hot swappable. The system continues to operate with the same configuration after it switches over to the redundant Supervisor Engine.

    Both the Cisco IOS software and Catalyst OS support the deployment of redundant Supervisor Engines for component level redundancy within a Catalyst 6500 chassis. However, the operational model for Supervisor Engine redundancy differs between Cisco IOS software and CatOS.

    Note: Redundancy is always enabled and cannot be disabled. Redundancy is enabled anytime the switch has two Supervisor Engines installed on it and the switch decides which specific redundancy mode to use in accordance to the type of images it has. The Cisco IOS and feature set that runs on both Supervisors must be the same for SSO redundancy.

    Hybrid Mode

    In CatOS, the foundation for supervisor redundancy is the high availability feature. This feature allows systems with dual supervisors to synchronize the protocol states between the active and standby Supervisor Engines. If an active supervisor failure were to take place, the standby supervisor then takes over system operation with accurate and up-to-date state information of the protocols that run on the switch. This allows a supervisor failover to take place in one to three seconds and requires no network reconvergence for Layer 2, 3, and 4 protocols. From a router perspective, the MSFC engines can be configured for redundancy as well with hybrid software.

    The Catalyst OS High Availability feature was disabled by default until Cisco Catalyst OS Release 8.5. The alternative is referred to as fast switchover. The fast switchover feature is the predecessor to the high availability feature. Therefore, it is the Supervisor Engine switchover mechanism in place when high availability is disabled or not supported in the software version. In order to reduce the switchover time, this feature skips some events that typically take place when a Supervisor Engine fails. Specifically, the fast switchover mechanism allows each line card to skip the respective software downloads and a portion of the diagnostics, which are normally a part of system re-initialization. The switchover still includes the restart of all protocols (Layer 2 and above), as well as the reset of all ports.

    The switchover performance with default settings that results takes approximately 28 seconds, plus the time it takes for the protocols to restart. High availability removes this limitation. High availability allows the active Supervisor Engine to communicate with the standby Supervisor Engine. This keeps feature protocol states synchronized. Synchronization between the Supervisor Engines allows the standby Supervisor Engine to take over in the event of a failure.

    By default on the Cisco Catalyst 6500 Series Switch, the Catalyst OS software images on the active and the standby Supervisor Engines must be the same. If the two supervisor images are not the same version during system bootup, the active Supervisor Engine downloads its current boot image to the standby Supervisor Engine. The NVRAM configuration of the active Supervisor Engine is also synchronized between the Supervisor Engines.

    The second portion of the Catalyst OS High Availability feature is called versioning. It depends on the high availability feature enabled in a dual Supervisor Engine configuration. This allows different but compatible images to run on the active and standby Supervisor Engines, thus disables the default supervisor image synchronization process. This feature is primarily used to simplify the software upgrade process when two Supervisor Engines are involved.

    Hybrid systems with redundant supervisor/MSFC combinations can optionally have two active MSFCs in the same chassis (referred to as Dual Router Mode). In this configuration, Hot Standby Router Protocol (HSRP) is configured internally between both active MSFCs. With Cisco IOS software, the standby MSFC is not fully operational. Therefore, it is not possible to run internal HSRP between the two MSFCs. External HSRP from the Cisco Catalyst 6500 to other routers in the network is supported in either Route Processor Redundancy (RPR), Route Processor Redundancy Plus (RPR+), or non-stop forwarding with stateful switchover (NSF/SSO) mode with the Cisco IOS software.

    Refer to Configuring Redundant Connections for more information.

    Native Mode

    Cisco IOS software on the Catalyst 6500 supports RPR, also known as Enhanced High System Availability (EHSA), RPR+, NSF/SSO and single router mode with stateful switchover (SRM/SSO). In this operational model, one supervisor/MSFC pair is fully operational and the other pair is in standby mode.

    The show module command lists the active and standby supervisors. There are heartbeat messages between two pairs to ensure rapid failure detection. There is no stateful protocol redundancy between Supervisor Engines with RPR or RPR+. The SSO redundancy mode provides the stateful protocol redundancy between Supervisor Engines in Cisco IOS and is equivalent in terms of functionality to the Cisco Catalyst OS High Availability redundancy mode.

    In Cisco IOS software, the supervisor and MSFC are each responsible for different functions and protocols (Layer 2 vs. Layer 3). However, the system is dependent on the availability of both engines for proper operation. Failure of either the supervisor or the MSFC in RPR/RPR+/SSO mode causes a switchover from the active supervisor to the standby supervisor/MSFC.

    Note: In Hybrid mode, the Supervisor Engine can remain fully operational if one MSFC fails. A MSFC failure does not necessarily cause a supervisor switchover, but can cause an MSFC failover only. This allows a cross model where the active Policy Feature Card (PFC) and the Switch Processor (SP) that runs Catalyst OS is fully functional in one slot, whereas the Route Processor (RP)/MSFC is fully functional in another slot.

    This section provides an overview of supervisor redundancy characteristics with RPR, RPR+, NSF/SSO and SRM/SSO:

    • RPR—The first redundancy mode of operation introduced in Cisco IOS software. In RPR mode, the startup configuration and boot registers are synchronized between the active and standby supervisors, the standby is not fully initialized, and images between the active and standby supervisors do not need to be the same. Upon switchover, the standby supervisor becomes active automatically, but it must complete the boot process. In addition, all line cards are reloaded and the hardware is reprogrammed. The RPR switchover time is 2 or more minutes.

    • RPR+—An enhancement to RPR in which the standby supervisor is completely booted and line cards do not reload upon switchover. The configuration that runs is synchronized between the active and the standby supervisors. All synchronization activities inherited from RPR are also performed. The synchronization is done before the switchover, and the information synchronized to the standby is used when the standby becomes active to minimize the downtime. No link layer or control-plane information is synchronized between the active and the standby supervisors. Interfaces can bounce after switchover, and the hardware contents need to be reprogrammed. The RPR+ switchover time is 30 or more seconds. The actual failover time is dependent on the size and complexity of the configuration.

    • NSF/SSO—Both the Cisco IOS software and the CatOS support NSF with SSO. The key differentiators apply in where and how these features are applied with the more advanced forms of these features deployed first in Cisco IOS. SSO expands the RPR+ capabilities to provide transparent failover of Layer 2 protocols when a supervisor failure occurs. SSO is stateful for Layer 2 protocols. The PFC and Distributed Forwarding Card (DFC) hardware tables are maintained across a switchover. This allows for transparent failover at Layer 2 and Layer 4. NSF works in conjunction with SSO to ensure Layer 3 integrity after a switchover. It allows a router that experiences the failure of an active supervisor to continue forwarding data packets along known routes, while the routing protocol information is recovered and validated. This forwarding can continue to take place by the leverage of restart mechanisms that allow peering arrangements to recover upon failover. This avoids unnecessary route flaps and network instability. The failover time is 0 to 3 seconds with NSF/SSO.

    • SRM/SSO—When the switch is powered on, SRM with SSO runs between the two Supervisor Engines. The Supervisor Engine that boots first becomes the active Supervisor Engine. The MSFC and PFC become fully operational. The configuration of the redundant Supervisor Engine and MSFC is exactly the same as the active Supervisor Engine and MSFC. Processes, such as routing protocols, are created on both the active MSFC and the redundant MSFC. The redundant Supervisor Engine is fully initialized and configured, which shortens the switchover time. The active Supervisor Engine checks the image version of the redundant Supervisor Engine when the redundant Supervisor Engine comes online. If the image on the redundant Supervisor Engine does not match the image on the active Supervisor Engine, RPR mode is used. If the active Supervisor Engine or MSFC fails, the redundant Supervisor Engine and MSFC become active. SRM with SSO supports a switchover time of 0 to 3 seconds for Layer 2 unicast traffic.

      Note: SRM with SSO is supported only on Supervisor Engine 720 and Supervisor Engine 32.

      The module status of the standby Supervisor Engine in the show module command output is different for the different redundancy modes for Native Cisco IOS:

      • RPR—Status shows Cold .

        Cold redundancy refers to the degree of resiliency that a redundant system traditionally provides. A redundant system is cold when no state information is maintained between the backup or standby system and the system it protects.

      • RPR+—Status shows Warm .

        Warm redundancy refers to a degree of resiliency beyond the cold standby system. In this case, the redundant system is partially prepared. However, the system does not have all the state information that the primary system knows for an immediate take-over. Some additional information must be determined or gleaned from the traffic flow or the peer network devices to handle packet forwarding.

      • SSO—Status shows Hot .

        Hot redundancy refers to a degree of resiliency where the redundant system is fully prepared to handle the traffic of the primary system. Substantial state information is saved, so the network service is continuous, and the effect on traffic flow is minimal or nil in the case of a failover.

    3. Verify the redundancy mode status from the active Supervisor Engine.

    5. Log your console session as a best practice.

      The log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot.

      For example, in HyperTerminal, choose Transfer > Capture Text in order to log a console session.

      Refer to Connecting a Terminal to the Console Port on Catalyst Switches for more information.

    6. Issue the copy start tftp command in order to back up the configuration.

      If you back up the configuration, the file can serve as a reference after the upgrade. Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for more information on the use of the copy start tftp command to back up configuration files.

    7. Verify that the Cisco IOS image (s3223*) required for the upgrade is on either Supervisor Engine bootflash ( sup-bootdisk: and subordinatesup-bootdisk: ), or on the CompactFlash card ( disk0: and subordinatedisk0: ) of both the Supervisor Engines.

Cat-6509#

      If you do not have the Cisco IOS image for upgrade on either Supervisor bootflash ( sup-bootdisk:    and   subordinatesup-bootdisk: ) or on CompactFlash card ( disk0:    and   subordinatedisk0:), go to step 8. If you have the Cisco IOS image installed, go to step 9.

    8. Complete this step only if the Cisco IOS Software image (s3223*) is not present from either Supervisor Engine bootflash ( sup-bootdisk: and subordinatesup-bootdisk: ) or on CompactFlash card ( disk0: and subordinatedisk0: ). Step 7 determines the need for this step.

      Note: You need to format the CompactFlash if it has not been used before, or if it was formatted with use of the CatOS Software algorithm. In order to format CompactFlash card on a Supervisor Engine 32, issue the format disk0: command. You can also free up space as necessary on the Flash devices. Issue the delete sup-bootdisk: filename or delete disk0: filename command in order to delete the file.

      Issue the copy tftp sup-bootdisk:  command first, then the copy tftp subordinatesup-bootdisk: or copy sup-bootdisk: subordinatesup-bootdisk: command in order to download the image to the Supervisor Engine bootflashes. Or, issue the copy tftp disk0: command first, then the copy tftp subordinatedisk0: or copy disk0: subordinatedisk0: command in order to download the image to the CompactFlash cards.

    12. Verify the redundancy status.

      Note: In order to run in RPR+ or SSO redundancy mode, image versions must be the same on the standby and active Supervisor Engines. In these redundancy modes, the active Supervisor Engine checks the image version of the standby Supervisor Engine when the standby Supervisor Engine comes online. If the image on the standby Supervisor Engine does not match the image on the active Supervisor Engine, the software sets the redundancy mode to RPR while a software upgrade is performed, and sets it back to SSO when the software upgrade is complete.

      Note: Establish a console connection to the Supervisor Engine in slot 6 simultaneously when the switchover is initiated from Supervisor Engine in slot 5.

      Note: In middle of the software upgrade procedure, the operational redundancy mode is RPR. This is evident from the show redundancy states command output shown in step 12. In RPR redundancy, during switchover, all switching modules are powered on again. So there is be a few minutes of downtime. During normal switchovers, if the operational redundancy is SSO, the installed switching modules are not reloaded, as both the startup and config that runs are synchronized continually from active to standby supervisor engine. The new active supervisor engine uses the current configuration.

      The procedure to upgrade Cisco IOS software on redundant Supervisor Engines is complete.

    Hybrid Mode

    In this section, you are presented with the information to upgrade the software images on a Catalyst 6500 Series Switch with redundant Supervisor Engines and MSFC that runs in Hybrid mode.

    It is recommended that a console connection be available for both Supervisor Engines for this procedure. The console port on the active Supervisor Engine is active and that on the standby Supervisor Engine is inactive.

    Note: The software images that this document uses are for example purposes only. Replace the images with the images that you use in your switch environment.

    Upgrade Catalyst OS

    Complete these steps in order to upgrade the Catalyst OS image on the active and standby Supervisor Engines:

    1. Establish a console connection to the active Supervisor Engine and verify the image version that runs on the Supervisor Engines.

      The images that this document uses are for example purposes only. Replace the images with the images that you use in your switch environment.

      Note: If you try to establish a console connection to the standby Supervisor Engine, this message displays as shown in the next code example.

      This module is now in standby mode.
Console is disabled for standby supervisor

    2. Check the status of the Supervisor Engine modules.

      Console> (enable) show module
 
Mod Slot Ports Module-Type               Model               Sub Status

!--- The active Supervisor Engine and MSFC are in slot 5 
      !--- and standby is in slot 6.

7   7    48    10/100BaseTX Ethernet     WS-X6348-RJ-45      no  ok

!--- Output suppressed.

      Note: The module status of the standby Supervisor Engine and MSFC in the show module command output is shown as standby in CatOS.

    3. Verify the redundancy mode status from the active Supervisor Engine.

      Console> (enable) show system highavailability 
 
Highavailability: disabled
Highavailability versioning: disabled
Highavailability Operational-status: OFF(high-availability-not-enabled)
      Console> (enable)

      Note: The default redundancy mode of operation in CatOS is fast switchover.

      Note: High availability versioning option allows you to run the different software images on the active and standby Supervisor Engines. High availability versioning is disabled by default. If the software versions of the two Supervisor Engines are different, or if the NVRAM configuration of the two Supervisor Engines is different, and if you do not enable high availability versioning, the active Supervisor Engine automatically downloads its software image and configuration to the standby Supervisor Engine.

    4. Verify the boot variables for both of the Supervisor Engines.

      Console> (enable) show boot 5
 
BOOT variable = bootdisk:cat6000-sup32pfc3k8.8-5-6.bin,1;
CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x2102
ignore-config: disabled
auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 9600
boot: image specified by the boot system commands

Image auto sync is enabled
Image auto sync timer is 120 seconds

      Console> (enable) show boot 6
 
BOOT variable = bootdisk:BTSYNC_cat6000-sup32pfc3k8.8-5-6.bin,1;
CONFIG_FILE variable = 

Configuration register is 0x2102
ignore-config: disabled
auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 9600
boot: image specified by the boot system commands

Image auto sync is enabled
Image auto sync timer is 120 seconds

    5. Log your console session as a best practice.

      The log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot.

      For example, in HyperTerminal, choose Transfer > Capture Text in order to log a console session. Refer to Understand the Terminal Connection to a Console Port on Catalyst Switches for more information.

    6. Issue the copy config tftp command on the Supervisor Engine and the copy start tftp command on the MSFC in order to back up the configuration.

      If you back up the configuration, the file can serve as a reference after the upgrade. Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for more information on use of the copy config tftp and copy start tftp commands to back up configuration files.

    7. Verify that the CatOS image (cat6000-sup32*) required for upgrade is on either active Supervisor Engine bootflash (bootdisk:) or the CompactFlash card (disk0:).

      Console> (enable) dir bootdisk:
 
 2277   -rw-  10025748    Oct 18 2006 23:34:28 cat6000-sup32pfc3k8.8-5-6.bin

      If you do not have the CatOS image for upgrade on either active Supervisor Engine bootflash (bootdisk:) or the CompactFlash card (disk0:), go to step 8. If you have the CatOS image installed, go to step 9.

    8. Complete this step only if the CatOS image (cat6000-sup32*) is not present in either the active Supervisor Engine bootflash (bootdisk:) or the CompactFlash card (disk0:).Step 7determines the need for this step.

      Note: You need to format the CompactFlash if it has never been used before, or if it was formatted with use of the Cisco IOS Software algorithm. In order to format CompactFlash card on a Supervisor Engine 32, issue the format disk0: command. You can also free up space as necessary on the Flash devices. Issue the delete bootdisk: filename or delete disk0: filename command in order to delete the file.

      Load the new Catalyst OS software image into either the bootflash or CompactFlash card of only the active Supervisor Engine. Issue the copy tftp bootdisk: or copy tftp disk0: command in order to download the new image to the active Supervisor Engine bootflash or to the CompactFlash card.

      Note: In order to copy the new image to the standby Supervisor Engine bootflash or CompactFlash, you can issue the copy y/bootdisk:<image.bin> x/bootdisk: or copy y/bootdisk:<image.bin> x/disk0: command (where  y is the active Supervisor Engine module number and x is the standby Supervisor Engine module number given in the show module command output).

      Verify that the new image is copied into the bootflash or CompactFlash card of the active Supervisor Engine.

    9. Modify the image auto sync timer to the lowest value of 10 seconds in order to speed up the sync process.

      By default, it is 120 seconds.

      Console> (enable) set boot sync timer 10 
Image auto sync timer set to 10 seconds.

    10. Clear the current boot variable on the active Supervisor Engine.

      Console> (enable) clear boot system all

      Note: When you clear the boot variable on the active Supervisor Engine, this does not clear the boot variable on the standby Supervisor Engine. You need to issue the clear boot system all 6 command in order to manually clear the boot variable on the standby Supervisor Engine. This step is optional.

      You need to format the CompactFlash if it has never been used before, or if it was formatted with use of the Cisco IOS Software algorithm. In order to format CompactFlash card on a Supervisor Engine 32, issue the format disk0: command. You can also free up space as necessary on the Flash devices. Issue the delete bootdisk: filename or delete disk0: filename command in order to delete the file.

      Load the new Catalyst OS software image into either the bootflash or CompactFlash card of only the active Supervisor Engine. Issue the copy tftp bootdisk: or copy tftp disk0: command in order to download the new image to the active Supervisor Engine bootflash or to the CompactFlash card.

      Console> (enable)

      Note: When you download a new image to the active Supervisor Engine, it is copied to the file system (in bootflash or on a Flash PC card). Because you did or did not configure this image as the boot image, the newly downloaded image is not copied to the standby Supervisor Engine automatically. In order to initiate the synchronization function between the active and standby Supervisor Engines, you must configure this newly downloaded image as the boot image on the active Supervisor Engine. Synchronization occurs when you change the boot variable. In approximately 120 seconds (here, 10 seconds), the image set as the boot entry on the active Supervisor Engine is copied to the bootflash on the standby Supervisor Engine. This is the image synchronization. This is an internal TFTP of the Catalyst OS image file and takes a few minutes to complete.

      Note: The configuration register in the startup-config must be set to autoboot (0x2102).

    12. When the images have been synchronized, verify that the new image is located on the standby Supervisor Engine and the boot variable is properly set.

    13. Enable high availability versioning on the active Supervisor Engine.

      With high availability versioning enabled, you can have two different but compatible images on the active and standby Supervisor Engines. The active Supervisor Engine exchanges image version information with the standby Supervisor Engine and determines whether the images are compatible to enable high availability. If the active and standby Supervisor Engines do not run compatible image versions, you cannot enable high availability.

      Note: If two software images are incompatible, the software upgrade process impacts the system operation (that is, be greater than the one to three second switchover time of a high-availability switchover) and no NVRAM configuration changes are synchronized between Supervisor Engines.

      Note: There is no software image version compatibility in the 8.x software release train. This includes major releases, such as 8.1(x) to 8.2(x) to 8.3(x) and so on. This also includes sub-releases, such as 8.1(1) to 8.1(2), 8.2(1) to 8.2(2) and so on.

      Console> (enable) set system highavailability versioning enable
Image versioning enabled.

      Note: Before the standby Supervisor Engine that runs the new software becomes active, versioning must be enabled. This allows the standby Supervisor Engine to reboot under the new version of CatOS while it remains the standby Supervisor Engine.

      Note: You can force another switchover in which the standby Supervisor Engine becomes the active Supervisor Engine in order to restore the original roles of the Supervisor Engines (their active and standby status).

      The procedure to upgrade Catalyst OS software on redundant Supervisor Engines is complete.

    Upgrade Cisco IOS

    Complete these steps in order to upgrade the Cisco IOS image on the active and standby MSFCs when the switch runs in the Hybrid mode:

    1. Establish a console connection to the active Supervisor Engine and verify the module status.

      Console> (enable) show module

!--- Output suppressed.

      Note: In RPR mode, the standby MSFC is not shown in the show module command output.

    2. Issue the switch console command in order to access the active MSFC.

      Console> (enable) switch console 
Trying Router-15...
Connected to Router-15.
Type ^C^C^C to switch back...

      If you are connected through a Telnet session or if the active MSFC is on the standby Supervisor Engine, issue the session 15 or session 16 command in order to access the active MSFC.

      Note: Active MSFC can either be on the active or standby Supervisor Engine in Hybrid mode.

    3. Verify the image version that runs on the active MSFC before you perform the upgrade.

    6. Issue the dir bootflash:  command in order to verify if the new image (c6msfc2a*) required for the upgrade is present in the bootflash of both the MSFCs.

      If the image is not present, issue the copy tftp bootflash: or copy tftp subordinatebootflash: command in order to copy the new image to both the active and standby MSFC bootflashes.

      Note: If you have dual MSFCs, you must download the image onto the standby MSFC bootflash separately. The image does not automatically download to the standby MSFC.

    7. Clear the current boot variables.

      Note: Your system is in RPR mode at this time, not in SSO mode. This is because when the two supervisors are on different images, SSO mode does not work. Once they both reload on the same image and the configurations sync, you are back in SSO mode.

    13. Issue the redundancy switch-activity force command in order to perform a manual switchover to the standby MSFC.

      Router#redundancy switch-activity force

      The active MSFC reloads and the standby MSFC becomes the newly active MSFC that runs the new image.

    14. Verify the image and redundancy mode that run on the standby MSFC.

      Note: You can force another switchover in which the standby MSFC becomes the active MSFC in order to restore the original roles of the MSFCs (their active and standby status).

      The procedure to upgrade Cisco IOS software on redundant MSFCs in Hybrid mode is complete.

    Upgrade VSS Core from Modular to Non-Modular Code

    A full upgrade (chassis reboots) is required when you change major versions of the software (modular to non-modular), and not simply move to a new version of modular; for example, when you upgrade from s72033-advipservicesk9_wan-vz.122-33.SXI6.bin to s72033-advipservicesk9_wan-mz.122-33.SXI7.bin.

    Issue the show file system command on the chassis in order to view the image locations.

    This example shows two supervisors in each chassis:

    VSS#show module switch all

Switch Number:     1    Role:   Virtual Switch Active

----------------------  -----------------------------

Mod Ports Card Type                              Model         Serial No.

--- ----- -------------------------------------- ------------- -----------

  1    5  Supervisor Engine 720 10GE (Active)    VS-S720-10G   SAL1223SVBW

  2    5  Supervisor Engine 720 10GE (RPR-Warm)  VS-S720-10G   SAL1223SVBV

    Complete these steps in order to upgrade the images to each supervisor in the VSS:

    1. Use TFTP in order to load the image on the active supervisor (most likely sup-bootdisk).

    2. Copy the same image to the secondary supervisor in the active chassis and to the two supervisors in the standby chassis. For example:

      • copy sup-bootdisk:<image_name> sw1-slot2-sup-bootdisk:

      • copy sup-bootdisk:<image_name> sw2-slot1-sup-bootdisk:

      • copy sup-bootdisk:<image_name> sw2-slot2-sup-bootdisk:

    3. Use the dir all command in order to verify that the images are present.

    4. Rewrite the boot statement (found in show run) in order to reflect the new image.

    5. Use the write memory command in order to save the configuration.

    6. Use the show bootvar command in order to verify boot order and config register.

    Verify

    There is currently no verification procedure available for this configuration.

    Troubleshoot

    Cannot Display Standby Stack Due to IPC Error

    This error message can appear in the show version command output. A similar error can appear in the show bootvar command output. This error message appears only when you have redundant Supervisor Engines and both run on different Cisco IOS software releases. This scenario is common when you upgrade the Cisco IOS software release in the Supervisor Engines.

    Once both supervisor engines run the same Cisco IOS software release, this error message must not be displayed.

    Note: In case the Cisco IOS version is not known on the redundant Supervisor, the chassis can show this Supervisor as unknown due to a possible mismatch in the Cisco IOS code versions. However, you can access the secondary Supervisor via the console port and perform a Cisco IOS upgrade procedure in order to match the version of the Supervisor code. Once the code is upgraded, the standby Supervisor automatically downloads the active configuration and VLAN database from the active supervisor.
