Chapter 7 Configuring the Cisco IOS XE In Service Software Upgrade Process
How to Perform the ISSU Process
This example shows how to reset and reload the current standby supervisor engine (slot 1) with the new
Cisco IOS XE software version. After you enter the commitversion command, the standby supervisor
engine boots in the Standby Hot state.
