Usage Guidelines
The issu loadversion command causes the standby supervisor engine to be reset and booted with the
new Cisco IOS software image specified by the command. If both the old image and the new image are
ISSU capable, ISSU compatible, and have no configuration mismatches, the standby supervisor engine
moves into Stateful Switchover (SSO) mode, and both supervisor engines move into the load version
(LV) state.
It will take several seconds after the issu loadversion command is entered for Cisco IOS software to
load onto the standby supervisor engine and the standby supervisor engine to transition to SSO mode.
Examples This example shows how to initiate the ISSU process:
Switch# issu loadversion 1 bootflash:new-image 2 slavebootflash:new-image
