Command History

Usage Guidelines The issu commitversion command verifies that the standby Route Processor (RP) has the new Cisco IOS

software image in its file system and that both RPs are in the run version (RV) state. If these conditions

are met, then the following actions take place:

• The standby RP is reset and booted with the new version of Cisco IOS software.

• If both images are compatible, the standby RP moves into the stateful switchover (SSO) mode and

is fully stateful for all clients and applications with which the standby RP is compatible.

• If both images are not compatible, the standby RP moves into Route Processor Redundancy Plus

(RPR+) mode or RPR mode.

• If all conditions are correct, the RPs are moved into final state, which is the same as initial state.

Issuing 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.

Issuing the issu commitversion command at this stage 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 a period of time and are satisfied with the new software

version.

Examples The following example causes the standby RP to be reset and reloaded with the new Cisco IOS software

version:

Router# issu commitversion a stby-disk0:c10k2-p11-mz.2.20040830

slot The specified slot on the networking device. Refer to your hardware

documentation for information on the number of slots on your networking

device.

active-image The new image to be loaded into the active networking device.
