Usage guidelines

The device supports automatic rollback and manual rollback.

You can use this command to perform a manual rollback while an ISSU is in one of the following states:

• Loaded.

• Switching.

• Switchover.

• Accepted.

If the ISSU is in Loading state, the rollback might fail. Use the display version command to examine the rollback result after the ISSU is complete.

If the ISSU is in Switching state, the entire system reboots automatically.

A rollback cancels only the software upgrade. It does not cancel the master/subordinate switchover you performed before the rollback by executing the issu run switchover command.

Rollback is not supported while an ISSU is in Committing state.

Examples

# Roll back to the original software versions.

This command will quit the ISSU process and roll back to the previous version. Continue? [Y/N]:y
