Native Mode. In this section, you are presented with the information to upgrade the software images on a Catalyst Series Switch with redundant Supervisor Engines that run in Native 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 images that this document uses are for example purposes only. Replace the images with the images that you use in your switch environment.

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

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. 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.

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. If you do not have the Cisco IOS image for upgrade on either Supervisor bootflash sup-bootdisk: and slavesup-bootdisk: or on CompactFlash card disk0: and slavedisk0: , go to step 8.

If you have the Cisco IOS image installed, go to step 9. Step 7 determines the need for this step. Note: You might need to format the CompactFlash if it has never 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 slavesup-bootdisk: or copy sup-bootdisk: slavesup-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 slavedisk0: or copy disk0: slavedisk0: command in order to download the image to the CompactFlash cards. Note: The configuration register in the startup-config must be set to autoboot 0x Note: Before you reset the standby Supervisor Engine, make sure you wait long enough to ensure that all configuration synchronization changes have completed.

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.

The old active Supervisor Engine in slot 5 reboots with the new image and becomes the standby Supervisor Engine. 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 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 running config are synchronized continually from active to standby supervisor engine.

The new active supervisor engine uses the current configuration. 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. In this section, you are presented with the information to upgrade the software images on a Catalyst Series Switch with redundant Supervisor Engines and MSFC that runs in Hybrid mode.

Complete these steps in order to upgrade the Catalyst OS image on the active and standby Supervisor Engines:. Establish a console connection to the active Supervisor Engine and verify the image version that runs on the Supervisor Engines. 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.

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. 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.

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. Issue the delete bootdisk: filename or delete disk0: filename command in order to delete the file. 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.

Verify that the new image is copied into the bootflash or CompactFlash card of the active Supervisor Engine. Modify the image auto sync timer to the lowest value of 10 seconds in order to speed up the sync process. 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. Set the boot variable on the active Supervisor Engine in order to boot the new Catalyst OS software image. 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 might or might not have configured 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 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. 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.

This is to designate that it has been synchronized from the boot-time image of 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. This includes major releases, such as 8. This also includes sub-releases, such as 8. Note: Before the standby Supervisor Engine that runs the new software becomes active, versioning must be enabled. It remains the standby Supervisor Engine and does not affect the operation of the active Supervisor Engine.

Wait for the modules to come online and verify the status of the modules from the active Supervisor Engine slot 6. If the system operates as expected, the boot configuration on the standby Supervisor Engine now slot 5 needs to be updated.

This can be accomplished by disabling versioning on the new active Supervisor Engine, which automatically enables the image synchronization feature. If the image is not present, issue the copy tftp bootflash: or copy tftp slavebootflash: command in order to copy the new image to both the active and standby MSFC bootflashes. The image does not automatically download to the standby MSFC.

Issue the show redundancy states command after few minutes in order to ensure the standby MSFC is fully online. 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. Issue the redundancy switch-activity force command in order to perform a manual switchover to the standby MSFC.

Enter Ctrl-C three times in order to go back to the Supervisor Engine and then verify the module status. Copy the same image to the secondary supervisor in the active chassis and to the two supervisors in the standby chassis. For example:. Use the dir all command in order to verify that the images are present. Use the write memory command in order to save the configuration.

Use the show bootvar command in order to verify boot order and config register. 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 are in process of upgrading the Cisco IOS software release in the Supervisor Engines. Once both supervisor engines run the same Cisco IOS software release, this error message should not be displayed. 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 running configuration and VLAN database from the active supervisor. Skip to content Skip to search Skip to footer.

The software image upgrade is necessary when: You want to implement new features in your network that are available in the new software release. A known bug affects your switch, and that bug is resolved in the next software release.

Supervisor Engine 32 with Catalyst OS versions 8. Background Information Supervisor Redundancy Catalyst Series Switches allow a redundant Supervisor Engine to take over if the primary Supervisor Engine fails in order to support fault resistance. Native Mode In this section, you are presented with the information to upgrade the software images on a Catalyst Series Switch with redundant Supervisor Engines that run in Native mode.

Complete these steps in order to upgrade the Cisco IOS software images on the active and standby Supervisor Engines: Establish a console connection to the active Supervisor Engine and verify that the image version runs on the Supervisor Engines. SSO—Status shows Hot. Verify the redundancy mode status from the active Supervisor Engine. Verify the boot variables for both of the Supervisor Engines. Issue the copy start tftp command in order to back up the configuration. Cat copy tftp disk0: Address or name of remote host []?

Loading sipbasek9-mz. Cat show run Building configuration Current configuration : bytes! Cat conf t Enter configuration commands, one per line. Cat config no boot system disk0:sipbasek9-mz. This enhancement allows you to accomplish this install with a single command line.

For example:. This process can help reduce the time to install images or maintenance packs on redundant systems. The Prepend option to the install bind command allows you to boot from the boot statement from the install bind command. Currently the install bind command in Modular Cisco IOS Software adds a boot statement after other boot statements in the queue. That additional statement causes a problem when you want to boot from the boot statement from the install bind command because boot commands are executed in the order they appear in the queue.

Note: If the binding is already present in the queue, then its position in the queue remains unchanged. The Optional overwrite destination search-root in Modular IOS install command eliminates the need for a two-step process to delete the old or unused search root before adding a new one.

During installation of the image, if the destination search root exists, this enhancement allows you to overwrite the existing search root. If you say yes, then the existing image is deleted and the new image is installed. If you say no, the installation exits. A pending option has been added to the show install command to provide more information about the contents of Modular Cisco IOS Software cache data.

Issue the copy command in order to copy files in Flash. Specify the source and destination file names. The example duplicates the file config. Issue the delete command in order to delete the files. Specify the full name of the file to delete. You cannot issue this command in order to view binary files, such as software images or the vlan. You can issue the copy command in order to upload and download files to a TFTP server.

Use the tftp keyword as the destination file name when you copy a file in order to upload the file to a TFTP server. Also, you can use the tftp: syntax to specify both the address of the TFTP server and the file name, at once. The last important command that is available is the tar command.

Here is an excerpt from the upgrade procedure that illustrates this process:. The example also shows how to extract the file content directly into Flash. A single command downloads the entire bundle into the switch. Issue the dir command in order to be sure that the image is available in Flash. You can also check that the file size of the image is consistent with the file size of the image on Cisco. Each time that you enter a long file name, use the cut-and-paste function of your terminal emulator in order to avoid a misspelling of the file name.

Issue the configure terminal command in order to enter configuration mode. The selection of which configuration file to use basically requires the same steps as the selection of a software image from which to boot. This feature can be useful when you want to create a backup of a configuration that you are about to change, for instance.

This example changes the default configuration file name from config. When you issue the write memory command or the copy running-config startup-config command, you can receive this output in some situations:. The workaround is to save the running configuration file in the flash: device and issue the boot config-file command.

The command instructs the router to boot from that file instead of nvram: on reload. The solution is to use the boot buffersize size configuration command in order to increase the size of the simulated NVRAM. The configuration file cannot be larger than the buffer size allocation.

The range is from to , bytes. Issue the reload command or cold boot the switch. After you issue the boot buffersize command, you do not need to use the boot config-file workaround. The management of software images and configuration is very simple on the Catalyst and Switches. There are two major hardware releases for the Catalyst and Series. The first generation only allows you to download a new software image. The second generation provides a way to upload and download the configuration.

The first generation runs software versions 5. The second generation runs software versions 6. From the main menu, choose [F] Firmware in order to access the Firmware configuration menu. For firmware upgrades, enter [F] Filename in order to specify the file name of the image. This example sets the collection file name to catEN. The release must run software version 6. Refer to Resetting Catalyst Switches to Factory Defaults in order to reset the Catalyst switch configurations to the factory defaults.

This can be necessary when you upload the file with a new name. Issue the touch command, for example, to create the file on the TFTP server. Make sure that you correctly set the file permissions and owner name. Assign an IP address to your switch and, if the switch management interface is not in the same IP subnet as the TFTP server, provide the switch with a default gateway. This section provides some examples of how to assign an IP address and a default gateway on the different Catalyst switches.

Ports that are assigned to VLAN 1 establish connectivity, which is the default setting for ports. This example assigns the address Next, add a default gateway so that the Catalyst switch can reach hosts that are outside of the switch subnet. The command is set ip route 0. This example assigns the IP address These series of Catalyst switches implement a virtual interface with the name interface vlan 1.

Refer to the Cisco documentation for your switch in order to determine if the switch allows a different VLAN. The subnet mask is Issue the ip default-gateway command in global configuration mode. Use menus or the command line in order to set an IP address and default gateway on the Catalyst and the Catalyst Series Switches.

This example assigns to the switch the IP address Note: If the switch already has an IP address assignment and you change the IP address settings, reset the switch for the changes to take effect. This next example configures The configuration allows the switch to reach devices that are outside of the switch IP subnet. Here is the example:. Skip to content Skip to search Skip to footer.

See the "Related Information" section for upgrade instructions on Catalyst switches. Prerequisites Requirements Cisco recommends that you have knowledge of Cisco switch hardware administration. Display the Configuration Issue the show config command in order to view the current configuration file. In this example, the ping command accesses the TFTP server. Complete these steps: Enter enable mode. Issue the download command in order to download the image. Switch format disk0: Format operation may take a while.

The dir Command The dir command lists the files that are available in the Flash device that you specify.

This example shows how to list files in bootflash: and slot0: Note: Use disk0: or disk1: if you have a Supervisor Engine Configuration has been copied successfully. Note: Use disk0: or disk1: if you have a Supervisor Engine Note: Issue the dir all command in order to see files with the "D" flag. Name of file to copy from [clac. Name of file to copy from [config]? A configuration file The default configuration file is config. A vlan. This file is very important because it provides the system with information such as: The image from which to boot Which configuration file to use, if it differs from the default Manage Files on the Flash The keyword flash: refers to the Flash device.

The dir command lists the files in Flash: Switch dir flash: Directory of flash: 3 -r-- Mar 01 cXL-h2s-mz Destination filename [config2. Switch dir flash: Directory of flash: 3 -r-- Mar 01 cXL-h2s-mz Here is an example: Switch delete flash:config2.

Delete flash:config2. Here is an example: Switch more flash:config. Here is an example: Switch ping Destination IP address or hostname []? Source filename [config. Loading config. Switch config boot system flash:cXL-h2s-mz Specify the Configuration File The selection of which configuration file to use basically requires the same steps as the selection of a software image from which to boot.

Switch config boot config-file config2. Compress the config. Disabling service compress-config. Catalyst Series and Catalyst Series The management of software images and configuration is very simple on the Catalyst and Switches. Then issue the appropriate TFTP upgrade command to carry out the firmware upgrade process.

Use the [F] Filename for firmware upgrades command to define the name of the upgrade file residing on that server. This upgrade will overwrite the firmware version V8. 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 images that this document uses are for example purposes only. Replace the images with the images that you use in your switch environment. Establish a console connection to the active Supervisor Engine and verify that the image version runs on the Supervisor Engines.

Note: If you try to establish a console connection to the standby Supervisor Engine, this message displays:. The module status of the standby Supervisor Engine in the show module command output is different for the different redundancy modes for Native IOS:. 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. 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.

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. 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. 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. If you do not have the Cisco IOS image for upgrade on either Supervisor bootflash sup-bootdisk: and slavesup-bootdisk: or on CompactFlash card disk0: and slavedisk0: , go to step 8.

If you have the Cisco IOS image installed, go to step 9. Step 7 determines the need for this step. Note: You might need to format the CompactFlash if it has never 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 slavesup-bootdisk: or copy sup-bootdisk: slavesup-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 slavedisk0: or copy disk0: slavedisk0: command in order to download the image to the CompactFlash cards. Note: The configuration register in the startup-config must be set to autoboot 0x Note: Before you reset the standby Supervisor Engine, make sure you wait long enough to ensure that all configuration synchronization changes have completed.

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.

The old active Supervisor Engine in slot 5 reboots with the new image and becomes the standby Supervisor Engine. 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 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 running config are synchronized continually from active to standby supervisor engine.

The new active supervisor engine uses the current configuration. 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.

In this section, you are presented with the information to upgrade the software images on a Catalyst Series Switch with redundant Supervisor Engines and MSFC that runs in Hybrid mode. Complete these steps in order to upgrade the Catalyst OS image on the active and standby Supervisor Engines:.

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

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. 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. Issue the delete bootdisk: filename or delete disk0: filename command in order to delete the file. 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. Verify that the new image is copied into the bootflash or CompactFlash card of the active Supervisor Engine.

Modify the image auto sync timer to the lowest value of 10 seconds in order to speed up the sync process. 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. Set the boot variable on the active Supervisor Engine in order to boot the new Catalyst OS software image.

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 might or might not have configured 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 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. 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. This is to designate that it has been synchronized from the boot-time image of 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.

This includes major releases, such as 8. This also includes sub-releases, such as 8. Note: Before the standby Supervisor Engine that runs the new software becomes active, versioning must be enabled. It remains the standby Supervisor Engine and does not affect the operation of the active Supervisor Engine. Wait for the modules to come online and verify the status of the modules from the active Supervisor Engine slot 6.

If the system operates as expected, the boot configuration on the standby Supervisor Engine now slot 5 needs to be updated. This can be accomplished by disabling versioning on the new active Supervisor Engine, which automatically enables the image synchronization feature. If the image is not present, issue the copy tftp bootflash: or copy tftp slavebootflash: command in order to copy the new image to both the active and standby MSFC bootflashes. The image does not automatically download to the standby MSFC.

Issue the show redundancy states command after few minutes in order to ensure the standby MSFC is fully online. 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.

Issue the redundancy switch-activity force command in order to perform a manual switchover to the standby MSFC. Enter Ctrl-C three times in order to go back to the Supervisor Engine and then verify the module status. Copy the same image to the secondary supervisor in the active chassis and to the two supervisors in the standby chassis. For example:. Use the dir all command in order to verify that the images are present.

Use the write memory command in order to save the configuration. Use the show bootvar command in order to verify boot order and config register. 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 are in process of upgrading the Cisco IOS software release in the Supervisor Engines. Once both supervisor engines run the same Cisco IOS software release, this error message should not be displayed. 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 running configuration and VLAN database from the active supervisor.

The software image upgrade is necessary when: You want to implement new features in your network that are available in the new software release. A known bug affects your switch, and that bug is resolved in the next software release. Supervisor Engine 32 with Catalyst OS versions 8. Background Information Supervisor Redundancy Catalyst Series Switches allow a redundant Supervisor Engine to take over if the primary Supervisor Engine fails in order to support fault resistance.

Native Mode In this section, you are presented with the information to upgrade the software images on a Catalyst Series Switch with redundant Supervisor Engines that run in Native mode. Complete these steps in order to upgrade the Cisco IOS software images on the active and standby Supervisor Engines: Establish a console connection to the active Supervisor Engine and verify that the image version runs on the Supervisor Engines.
