Step 17
issu runversion
Example:
Router# issu runversion
Run the consolidated package that was loaded in
Step 16.
Note If this command is entered before the
terminal state is reached, a “
peer is not
online
” or “Standby RP is not in
terminal state
” error message will be seen
and the issu runversion command will not
work. If the issu runversion command does
not run for these reasons, wait for the
“
terminal state is reached” message to
appear and retry the issu runversion
command. You can also monitor the terminal
state using the show platform command.
After ISSU runversion is completed, a switchover
wil
l automatically occur and the standby RP will
become the active RP.
Step 18
telnet ip-address port
Example:
[unix-server-1 ~]$ telnet 172.17.52.157 2003

Log in to the RP being upgraded, preferably using
the RP’s console port, to complete the upgrade. (This
is the new active RP, that was the standby RP prior to
the ISSU process.)
Note Ensure the hostname does not end in “-stby”
after logging into the RP, as this indicates
that the RP being accessed is still the standby
RP.
There are many ways to log on to a console port. The
e
xample shows access to the console port from a
UNIX host using telnet.
Step 19
issu acceptversion
Example:
Router# issu acceptversion
(Optional) Stops the ISSU rollback timer.
This step is optional as long as St
ep 20 is completed
before the rollback timer expires.
Step 20
issu commitversion
Example:
Router# issu commitversion
Completes the ISSU upgrade.
