Aborting a Software Upgrade During ISSU
You can abort the ISSU process at any stage manually (prior to entering the issu commitversion
command) by entering the issu abortversion command. The ISSU process also aborts on its own if the
software detects a failure.
Note
If you enter the issu abortversion command before the standby supervisor engine becomes hot, the
traffic might be disrupted.
If you abort the process after you enter the issu loadversion command, the standby supervisor engine is
reset and reloaded with the original software.
If the process is aborted after you enter either the issu runversion or issu acceptversion command, then
a second switchover is performed to the new standby supervisor engine that is still running the original
software version. The supervisor engine that had been running the new software is reset and reloaded
with the original software version.
Ensure that the standby supervisor engine is fully booted before entering the abortversion command on
