Graceful Shutdown - 3Com VCX v7111 User Manual

acgwAdminState
acgwAdminStateLockControl
The acgwAdminState is used either to request (set) a shutdown (0), undo shutdown (2), or to
view (get) the gateway condition (0 = locked; 1 = shutting down; 2 = unlocked).
The acgwAdminStateLockControl is used to set a time limit (in seconds) for the shutdown
where 0 means shutdown immediately (forced), -1 means no time limit (graceful), and x
where x>0 indicates a time limit in seconds (timed limit is considered a graceful shutdown).
The acgwAdminStateLockControl must be set first followed by the acgwAdminState.

Graceful Shutdown

acgwAdminState is a read-write MIB object. When a get request is sent for this object, the
agent returns the board's current administrative state.
The possible values received on a get request include the following:
locked(0): the board is locked
shuttingDown(1): the board is currently performing a graceful lock
unlocked(2): the board is unlocked
On a set request, the manager supplies one of the following desired administrative states:
locked(0)
unlocked(2)
When the board changes to either shuttingDown or locked state, an adminStateChange
alarm is raised. When the board changes to an unlocked state, the adminStateChange alarm
is cleared.
Before setting acgwAdminState to perform a lock, acgwAdminStateLockControl should be
set first to control the type of lock that is performed. The possible values for the
acgwAdminStateLockControl include the following:
1 = Perform a graceful lock. Calls are allowed to complete. No new calls are allowed to
be originated on this device.
0 = Perform a forced lock. Calls are immediately terminated.
Any number greater than 0 = Time in seconds before the graceful lock turns into a forced
lock.
