Upgrading a VSS
Verify the New Image on the VSS Standby Chassis
You can now enter the show issu state detail command and the show redundancy command to check
that both chassis are in the ISSU Load Version state and SSO redundancy state. In this example, the
VSS standby chassis is now running the “newversion” image.
Router# show issu state detail
Slot = 1/2
RP State = Active
ISSU State = Load Version
Boot Variable = disk0:s72033-oldversion.v1,12
Operating Mode = sso
Primary Version = disk0:s72033-oldversion.v1
Secondary Version = disk0:s72033-newversion.v2
Current Version = disk0:s72033-oldversion.v1
Variable Store = PrstVbl
Slot = 2/7
RP State = Standby
ISSU State = Load Version
Boot Variable =
disk0:s72033-newversion.v2,12;disk0:s72033-oldversion.v1,12
Operating Mode = sso
Primary Version = disk0:s72033-oldversion.v1
Secondary Version = disk0:s72033-newversion.v2
Current Version = disk0:s72033-newversion.v2
Router# show redundancy status
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Secondary
Unit ID = 18
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = sso
Maintenance Mode = Disabled
Communications = Up
client count = 132
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
keep_alive threshold = 18
RF debug mask = 0x0
Execute a Switchover to the New Image
When the VSS standby chassis is successfully running the new image in SSO redundancy state, enter the
issu runversion command to force a switchover. The upgraded VSS standby chassis takes over as the
new active chassis, running the new image. The formerly active chassis reloads and initializes as the new
VSS standby chassis in SSO mode, running the old image (in case the software upgrade needs to be
aborted and the old image restored). This step is complete when the chassis configuration is
synchronized, as indicated by the “Bulk sync succeeded” message.
Router# issu runversion
This command will reload the Active unit. Proceed ? [confirm]
