Setting the Administrative State
Use the set-admin-state MML command to change the administrative state of various components. The
Cisco PGW 2200 Softswitch generates a log message every time you enter the set-admin-state
command. The system also generates an alarm every time one issues the set-admin-state command at
either the Cisco PGW 2200 Softswitch, media gateway, signaling service, or trunk group level.
The following sections present procedures that use the set-admin-state command:

Setting the Administrative State of a Cisco PGW 2200 Softswitch
To set the administrative state of a Cisco PGW 2200 Softswitch, perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-admin-state: mgc : state command.
Where:
• mgc—MML name of the Cisco PGW 2200 Softswitch.
• state—Administrative state that you want to set. The following states are valid:
– lock—Makes all bearer channels unavailable for call processing. If the state is set to lock, active
calls go into pending state, where calls remain until either party voluntarily releases the call.
New calls are disallowed.
– unlock—Makes all bearer channels available for call processing. If the state is set to unlock, the
Cisco PGW 2200 Softswitch becomes available. New calls are allowed to use the unlocked
bearer channels.
– reset—Clears local and remote blocking on all bearer channels and they take the blocking state
of the remote side.
For example, to set the administrative state of a Cisco PGW 2200 Softswitch called mgc1 to unlock, enter
the
set-admin-state:mgc1:unlock command.
