issu commitversion
issu commitversion
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 Enabled by default.
Command Modes Privileged EXEC mode
Command History
Usage Guidelines The issu commitversion command verifies that the standby 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 standby supervisor engine is reset and booted with the new version of Cisco IOS software.
• The standby supervisor engine moves into the Stateful Switchover (SSO) mode and is fully stateful
for all clients and applications with which the standby supervisor engine is compatible.
• 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 state without starting a new ISSU process.
Entering the issu commitversion command without entering the issu acceptversion command is
equivalent to entering both the 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 example shows how you can configure the standby supervisor engine to be reset and reloaded with
the new Cisco IOS software version:
Switch# issu commitversion 1
Switch#
standby-slot Specifies the slot number for the currently active supervisor engine.
standby-image-new (Optional) Name of the new image on the currently active supervisor engine.
