Upgrading a VSS
If the ICS is participating in the eFSU upgrade, you must ensure that the ICS is up and running before
performing each ISSU step. If the ICS is not up and running you need to wait until it is online. You can
verify that the ICS is online by entering the show module command.
Performing an eFSU Upgrade on an Installed Modular Image
To perform an eFSU upgrade (or downgrade) of an ION VSS, perform this task:
Step 7 Router# issu commitversion Loads the new software image onto the standby chassis.
Step 8 Router# show issu state [switch/slot][detail] Verifies the status of the downgrade process. If the
downgrade was successful, both the active and standby
chassis are running the new software version.
Command Purpose
Command Purpose
Step 1 Router# copy tftp disk_name Uses TFTP to copy the new software image to flash memory
on the active and VSS standby chassis (disk0: and
slavedisk0:). Answer the prompts to identify the name and
location of the new software image.
Note You should have a console on both the active and
VSS standby supervisor engines because you will
go back and forth between them.
Step 2 Router# install file bootdisk:filename
bootdisk: /location
Installs the modular image on to both the active and VSS
standby supervisor engines.
Step 3 Router# show issu state [switch/slot][detail] Verifies the status of the upgrade process; status should
display ‘Init’.
Step 4 Router# issu loadversion new-image Starts the upgrade process by loading the installed software
image onto the active and VSS standby chassis. The image
name includes the path of the target image to be loaded, in
the format devicename:filename.
It may take several seconds for the new image to load and
for the VSS standby chassis to transition to SSO mode.
Note This command will cause the VSS standby chassis
to reload.
Step 5 Router# show issu state [switch/slot][detail] Verifies the status of the upgrade process; status should
display ‘Load Version’.
Step 6 Router# issu runversion Forces a switchover, causing the VSS standby chassis to
become active and begin running the new software. The
previously active chassis becomes VSS standby and boots
with the old image.
Step 7 Router# show issu state [switch/slot][detail] Verifies the status of the upgrade process; status should
display ‘Run Version’.
