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.

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 for Option 2

To roll back to the original release:

Copy the original startup configuration from the TFTP server to the startup configuration on the active

Step 1

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 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.

Reload the active ESR-PRE2 using the reload command.

•

You have now reverted to the original system configuration.

Upgrade Option 3: ESR-PRE1 Upgrade with RPR Switchover

This procedure assumes the following configuration:

•

You need two ESR-PRE2s with boot image installed in the bootflash to replace the ESR-PRE1s.

This upgrade procedure is service affecting. It requires a sequential PRE hardware replacement and a

switchover from the active to standby PRE. During the switchover in

available for user traffic.

Note

At several steps during this procedure, two PREs will alternately be using their FastEthernet0/0/0 NME

ports to copy files to and retrieve files from your TFTP server. Be certain that the FastEthernet0/0/0 port

that is not in current use is shut down (using the shut command) and that the one in use is active (using

the no shut command). Otherwise, collisions are likely if both ports are using the same IP address.

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.
