Purpose
Revert
the firmware level to the previous
level of firmware that is installed on the appliance.
Syntax
firmware
rollback
Parameters
None.
Usage Notes
- The appliance holds at
most two levels of firmware, the active
one and the alternate. Successive invocations of the firmware
rollback command result in switching back and forth between
the two images.
- This command rolls back the configuration.
After the rollback,
the configuration is in the state it was in before the last upgrade.
- This command rolls back the component firmware. Because each component
can have only one copy of component firmware, the component firmware
from the version that is rolled back is reinstalled to the component.
- The appliance is rebooted as part of this operation, so network
connectivity is disrupted. Therefore, it is recommended that this
command be typically run from the serial console.
Example
