7-18
Disabled state—The state for the standby supervisor engine while this engine is resetting.
Init state—The initial state is two supervisor engines, one active and one standby, before the ISSU
process is started. It is also the final state after the ISSU process completes.
Load version (LV) state—The standby supervisor engine is loaded with the new version of Cisco
IOS software.
Run version (RV) state—The issu runversion command forces the switchover of the supervisor
engines. The newly active supervisor engine now runs the new Cisco IOS software image.
System reset (SR) state—This state occurs either when you enter the issu abortversion command
before the Init state is reached, or if the rollback timer expires before you execute the
issu acceptversion command.
