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) through the management port, the serial port console, and remotely through
the traffic management ports. You can use the command menu to reset the unit if TMOS
®
has locked up. You can also
get console access to the Traffic Management Operating System itself, so that you can configure TMOS from the
command line interface.
AOM consists of the host console shell (hostconsh), the shell that provides access to the command menu, and the
Command Menu, which contains the options for AOM.
AOM Command Menu options
The AOM Command Menu provides the AOM options for the BIG-IP system.
