Administering the Media Gateway
Administering the Media Gateway requires you to administer the Primary Search Timer, the Total Search
Timer, and the MGC list Transition Point. You also administer an MGC list of up to four alternate
controllers for the gateway.
Administering the gateway timers and Transition Point
To administer the gateway timers and Transition Point
1 Administer the gateway's Primary Search Timer (the length of time that the gateway spends
trying to connect to the primary server) by typing set mgp reset-times primary-search <search-
time> at the Command Line Interface (CLI). The <search-time> values are 1-60 minutes.
NOTE:
The Primary Search Timer value should be shorter than both the Total Search Timer and
the Link Loss Delay Timer.
2 Administer the Total Search Timer (the length of time that the gateway spends trying to connect
to all alternate resources) by typing set mgp reset-times total-search <search-time> at the
Command Line Interface (CLI). The <search-time> values are 1-60 minutes.
