The following example shows how to define an MGCP map:
hostname(config)# policy-map type inspect mgcp sample_map
hostname(config-pmap)# parameters
hostname(config-pmap-p)# call-agent 10.10.11.5 101
hostname(config-pmap-p)# call-agent 10.10.11.6 101
hostname(config-pmap-p)# call-agent 10.10.11.7 102
hostname(config-pmap-p)# call-agent 10.10.11.8 102
hostname(config-pmap-p)# gateway 10.10.10.115 101
hostname(config-pmap-p)# gateway 10.10.10.116 102
hostname(config-pmap-p)# gateway 10.10.10.117 102
hostname(config-pmap-p)# command-queue 150

Configuring MGCP Timeout Values

The timeout mgcp command lets you set the interval for inactivity after which an MGCP media
connection is closed. The default is 5 minutes.
The timeout mgcp-pat command lets you set the timeout for PAT xlates. Because MGCP does not have
a keepalive mechanism, if you use non-Cisco MGCP gateways (call agents), the PAT xlates are torn
down after the default timeout interval, which is 30 seconds.

Verifying and Monitoring MGCP Inspection

The show mgcp commands command lists the number of MGCP commands in the command queue. The
show mgcp sessions command lists the number of existing MGCP sessions. The detail option includes
additional information about each command (or session) in the output. The following is sample output
from the show mgcp commands command:
hostname# show mgcp commands
1 in use, 1 most used, 200 maximum allowed
CRCX, gateway IP: host-pc-2, transaction ID: 2052, idle: 0:00:07
The following is sample output from the show mgcp detail command.
hostname# show mgcp commands detail
1 in use, 1 most used, 200 maximum allowed
CRCX, idle: 0:00:10
OL-12172-03
Use the gateway command to specify which group of call agents are managing a particular gateway.
The IP address of the gateway is specified with the ip_address option. The group_id option is a
number from 0 to 4294967295 that must correspond with the group_id of the call agents that are
managing the gateway. A gateway may only belong to one group.
If you want to change the maximum number of commands allowed in the MGCP command queue,
enter the following command:
hostname(config-pmap-p)# command-queue command_limit
Gateway IP host-pc-2
Transaction ID 2052
Endpoint name aaln/1
Call ID 9876543210abcdef
Connection ID
Media IP 192.168.5.7
Media port 6058
