Commits a firmware upgrade.
Privileged EXEC mode
The firmware download command updates the secondary partitions only. When the firmware download command completes successfully and the device reboots, the system swaps partitions. The primary partition (with the previous firmware) becomes the secondary partition, and the secondary partition (with the new firmware) becomes the primary partition.
By default, firmware download automatically commits the firmware after the device reboots. If you disable auto-commit mode when running firmware download, you must execute firmware commit to commit the new firmware to the secondary partition.
You must run the firmware download command with the nocommit parameter set for the following firmware commit operation to succeed.
To commit the firmware:
device# firmware commit Validating primary partition... Doing firmwarecommit now. Please wait ... Replicating kernel image ............... FirmwareCommit completes successfully.
