Hitless Layer 2 OS upgrade loads from the primary and secondary images on the Management modules.
The first step in performing a hitless Layer 2 OS upgrade is to copy the version 02.3.00 or later images
into the flash memory of the active and standby management modules.
For instructions for copying these files, see Upgrading the management module monitor and boot images
and Upgrading the management module IronWare image.
Setting up consoles
Hitless Layer 2 OS upgrade is executed at the active management module. During the process of
upgrading the image, control of the switch is shifted to the standby management module. For this reason,
you need to have management sessions enabled on both the active and the standby management modules.
When the reload is complete, the management module that was in the standby condition at the beginning
will be in the active state. If you want the original management module to be active, you must manually
fail-over control to it.
Executing the Hitless upgrade command
To begin the process of a hitless upgrade, use the following command:
BigIron RX(config)# hitless-reload mp primary lp primary
Syntax: hitless-reload mp [primary | secondary ] lp [primary | secondary]
The mp parameter specifies that the management module will be reloaded with either the primary or
secondary image as directed.
The lp parameter specifies that the management module will be reloaded with either the primary or
secondary image as directed.
Verify the new software image
Enter the show version command at any CLI level, and verify that all management and interface modules
are running the new software image version.
