firmware commit

Commits a firmware upgrade.

Synopsis firmware commit

Operands None

Defaults None

Command Modes Privileged EXEC mode

Description Use this command to copy the firmware image from the primary partition to the secondary

partition. This command is effective only after a firmware download (with auto-commit mode

disabled) and a reboot.

Usage Guidelines The firmware download command updates the secondary partitions only. When the

firmware download command completes successfully and the switch 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 switch reboots. If you

disable auto-commit mode when running firmware download, you must execute one of the

following two commands after you reboot the switch:

• firmware commit: Copies the primary partition (with the new firmware) to the secondary

partition and commits the new firmware to both partitions.

• firmware restore: Copies the secondary partition (with the previous firmware) to the primary

partition and restores the original firmware version.

This command is supported only on the local management modules.

You must run the firmware download command with the nocommit parameter set for the following

firmware commit operation to succeed.

Examples To commit the firmware:

switch# firmware commit
