Catalyst 4500 Series Switch Cisco IOS Release Strategy

Note Release 12.1(26)E3 is a General-Deployment release candidate, and is the last release in the 12.1E train to receive GSBU maintenance. Customers desiring support for newer features, or for ongoing maintenance, should consider the 12.2(18)EW release train.

Cisco IOS Release 12.2EW train offers the latest features for the Catalyst 4500 Series supervisor engines. Customers with Catalyst 4500 series supervisor engines who need the latest hardware support and software features should migrate to Cisco IOS Release 12.2(25)EWA.

Cisco IOS Software Release 12.2(18)EW1 and all subsequent 12.2(18)EW maintenance releases have only the feature set based on Cisco IOS Release 12.2(18)EW for the Catalyst 4500 Series supervisor engines. Customers with Catalyst 4500 Series supervisor engines who require the stability of a bug fix maintenance release should stay with the Cisco IOS Software Release 12.2(18)EW maintenance releases.

Cisco IOS Releases 12.1(19)E1 through 12.1(26)E have only the feature set based on Cisco IOS Release 12.1(12c)EW1 for the Catalyst 4500 Series supervisor engines. Customers with Catalyst 4500 Series supervisor engines who require the stability of a maintenance release should migrate from 12.1E releases to the Cisco IOS Release 12.2(18)EW maintenance releases.

New and Changed Information

There are no new hardware or software features because this is an E train release.

Upgrading the System Software

If you have a Catalyst 4500 series switch running Cisco IOS Release 12.1(11b)EW1 or earlier, and you want to upgrade your switch to Cisco IOS Release 12.1(26)E3, you must upgrade the Supervisor Engine III or Supervisor Engine IV ROMMON version at least to Release 12.1(12r)EW, in addition to upgrading the Cisco IOS software.

The following sections describe how to upgrade your switch software:

•Upgrading the Supervisor Engine ROMMON and the Cisco IOS Software

•Upgrading the Supervisor Engine ROMMON

•Upgrading the Cisco IOS Software

Upgrading the Supervisor Engine ROMMON and the Cisco IOS Software

This section describes how to upgrade the ROMMON software and the Cisco IOS software on your switch in a single procedure. If this process fails, upgrade your ROMMON software as described in "Upgrading the Supervisor Engine ROMMON" section, and then upgrade your Cisco IOS software as described in the "Upgrading the Cisco IOS Software" section.

Caution To avoid actions that might make your system unbootable, read this entire section before starting the upgrade.

To upgrade the ROMMON software and Cisco IOS software on your switch, follow this procedure:

Step 1 Download the cat4000-sup3-promupgrade-121_12r_EW program from Cisco.com, and place it on a TFTP server in a directory that is accessible from the switch to be upgraded.

The cat4000-sup3-promupgrade-121_12r_EW programs are available at the same location on Cisco.com from which you download Catalyst 4500 system images.

Step 2 Download the Cisco IOS Release 12.1(26)E3 image from Cisco.com, and place it on a TFTP server in a directory that is accessible from the supervisor to be upgraded.

Step 3 Use the dir bootflash: command to ensure that there is sufficient space in Flash to store the promupgrade image and the Cisco IOS software image. If there is insufficient space, delete one or more images, and then enter the squeeze bootflash: command to reclaim the space.

If you are using a Compact Flash card, use the slot0: command instead of the bootflash: command.

Step 4 Download the cat4000-sup3-promupgrade-121_12r_EW program into Flash memory using the copy tftp command.

The following example shows how to download the promupgrade image cat4000-sup3-promupgrade-121_12r_EW from the remote host 172.20.58.78 to bootflash:

Step 6 Use the show bootvar command to display the files specified in the BOOT variable.

The following example shows how to display the contents of the BOOT variable:
Switch# show bootvar
BOOT variable = bootflash:cat4000-is-mz.121-8a.EW
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2100
Switch# 
Step 7 Enter the no boot system flash bootflash:file_name command to clear the BOOT variable.

The following example shows how to clear the cat4000-is-mz.121-8a.EW file and save the BOOT variable:
Switch# configure terminal
Switch(config)# no boot system flash bootflash:cat4000-is-mz.121-8a.EW
Switch(config)# exit
Switch# write
Building configuration...
Compressed configuration from 3641 to 1244 bytes [OK]
Switch#
Step 8 Use the show bootvar command to verify that the BOOT variable is empty.

The following example shows an empty the BOOT variable:
Switch# show bootvar
BOOT variable does not exist
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2100
Switch# 
Step 9 Use the boot system flash command to add the cat4000-sup3-promupgrade-121_12r_EW program and the Cisco IOS software image to the BOOT variable.

The following example shows how to add the cat4000-sup3-promupgrade-121_12r_EW program and the cat4000-is-mz.121-14.E1 image to the BOOT variable:
Switch# configure terminal
Switch(config)# boot system flash bootflash:cat4000-sup3-promupgrade-121_12r_EW 
Switch(config)# boot system flash bootflash:cat4000-is-mz.121-14.E1 
Switch(config)# exit
Switch# write
Building configuration...
Compressed configuration from 3723 to 1312 bytes [OK]
Switch#
Step 10 Use the show bootvar command to verify that the BOOT variable contains the promupgrade image and Cisco IOS image and that the configuration register is set to 0x2102. If the configuration register is not set to 0x2102, proceed to step 11. If the configuration register is set to 0x2102, proceed to step 12.

The following example shows that the cat4000-sup3-promupgrade-121_12r_EW program and the cat4000-is-mz.121-14.E1 image are in the BOOT variable and that the configuration register is set to 0x21020:
Switch# show bootvar
BOOT variable = bootflash:cat4000-sup3-promupgrade-121_12r_EW,1;cat4000-is-mz.121-14.E1,1
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102
Switch# 
Step 11 Use the configure-register command to set the configuration register to 0x2102.

The following example show how to set the second least significant bit in the configuration register:
Switch# configure terminal
Switch(config)# configure-register 0x2102
Switch(config)# exit
Switch# write
Building configuration...
Compressed configuration from 3723 to 1312 bytes [OK]
Switch#
Step 12 Enter the reload command to reboot and upgrade the switch. The switch upgrades the ROMMON and installs the new Cisco IOS image.

Caution The upgrade and reboot may require up to 15 minutes to complete. Do not disturb your switch during this process. If the process fails during the reboot, you must upgrade the ROMMON (as described in the "Upgrading the Supervisor Engine ROMMON" section) and then upgrade the Cisco IOS software (as described in "Upgrading the Cisco IOS Software" section).

The following example shows the output from the upgrade and reboot:
Switch# reload
Proceed with reload? [confirm]

Upgrading the Supervisor Engine ROMMON

Caution To avoid actions that might make your system unbootable, read this entire section before starting the upgrade.

If you have a Catalyst 4500 series switch running Cisco IOS Release 12.1(11b)EW1 or earlier, and you want to upgrade your switch to Cisco IOS Release 12.1(26)E3, you must upgrade the Supervisor Engine ROMMON to Release 12.1(12r)EW or higher. When you upgrade and boot the Cisco IOS software to Release 12.1(26)E3, the field programmable gate array (FPGA) is automatically upgraded.

Follow this procedure to upgrade your Supervisor Engine ROMMON to Release 12.1(12r)EW:

Step 1 Directly connect a serial cable to the console port of the Supervisor Engine III.

Note This section assumes that the console baud rate is set to 9600 (default). If you want to use a different baud rate, change the configuration register value for your switch.

Step 2 Download the cat4000-sup3-promupgrade-121_12r_EW program from Cisco.com, and place it on a TFTP server in a directory that is accessible from the switch to be upgraded.

The cat4000-sup3-promupgrade-121_12r_EW programs are available at the same location on Cisco.com where you download Catalyst 4500 series switch system images.

Step 3 Use the dir bootflash: command to ensure that there is sufficient space in Flash to store the promupgrade image. If there is insufficient space, delete one or more images and then enter the squeeze bootflash: command to reclaim the space.

If you are using a Compact Flash card, use slot0: instead of bootflash:.

Step 4 Download the cat4000-sup3-promupgrade-121_12r_EW program into Flash memory using the copy tftp command.

The following example shows how to download the promupgrade image cat4000-sup3-promupgrade-121_12r_EW from the remote host 172.20.58.78 to bootflash:
Switch# copy tftp: bootflash:
Address or name of remote host [172.20.58.78]? 
Source filename [cat4000-sup3-promupgrade-121_12r_EW]? 
Destination filename [cat4000-sup3-promupgrade-121_12r_EW]? 
Accessing tftp://172.20.58.78/ cat4000-sup3-promupgrade-121_12r_EW...
