issu commitversion
issu commitversi on
To load the new Cisco IOS software image into the new standby supervisor engine, use the issu
commitversion command.
issu commitversion standby-slot [standby-image- new]
Syntax Description
Defaults E nabled by default .
Command Modes Privileged EXE C mode
Usage Guidelines The issu commitversion command verifies that the stan dby supervisor engine has the new Cisco IOS
software image in its file system and that both supervisor engines are in the run version (RV) state. If
these conditions are met, the following actions take place:
• The sta ndby supervisor eng ine is reset and booted with t he new version of Cisco IOS softw are.
• The sta ndby supervisor engine moves into the Stateful Switchover (SSO) mode and is fully stateful
for all clients and applicati ons with which the standby supe rvisor engine is comp atible.
• The supervisor engines are moved into final state, which is the same as initial state.
Entering the issu commitversion command completes the In Service Software Upgrade (ISSU) process.
This process cannot be stopped or reverted to its original sta te without starting a new ISSU process.
Entering the issu commitversion command without entering the issu acceptversion command is
equivalent to entering both th e issu acceptversion and the issu commitversion commands. Use the
issu commitversion command if you do not intend to run in the current state for an extended period of
time and are satisfied with the new software version.
Examples This e xample shows how you can co nfigure the s tandby sup ervisor engine to be rese t and re loaded w ith
the new Cisco IOS software versio n:
