Always-On Management
The Always-On Management (AOM) subsystem enables you to manage the BIG-IP
®
system remotely using
SSH or serial console, even if the host is powered down. The AOM Command Menu operates independently
of the BIG-IP Traffic Management Operating System
®
(TMOS).
You can use the command menu to reset the unit if TMOS
®
has locked up, or get access to TMOS directly,
so that you can configure it from the command line interface.
AOM consists of the host console shell (hostconsh) and the AOM Command Menu, which contains the
options for AOM.
Note: The available functionality and options in AOM vary depending on the platform type.
