Cisco ASA Series Firewall CLI Configuration Guide
Chapter 14 Inspection for Voice and Video Protocols
MGCP Inspection
hostname(config-class)# no inspect mgcp
hostname(config-class)# inspect mgcp mgcp-map
Note If you are editing the default global policy (or any in-use policy) to use a different MGCP
inspection policy map, you must remove the MGCP inspection with the no inspect mgcp
command, and then re-add it with the new MGCP inspection policy map name.
Step 5 If you are editing an existing service policy (such as the default global policy called global_policy), you
are done. Otherwise, activate the policy map on one or more interfaces.
service-policy policymap_name {global | interface interface_name}
Example:
hostname(config)# service-policy global_policy global
The global keyword applies the policy map to all interfaces, and interface applies the policy to one
interface. Only one global policy is allowed. You can override the global policy on an interface by
applying a service policy to that interface. You can only apply one policy map to each interface.
Configuring MGCP Timeout Values
You can configure several MGCP global timeout values on the Configuration > Firewall > Advanced
> Global Timeouts page. You can set the interval for inactivity after which an MGCP media connection
is closed (default is 5 minutes). You can also set the timeout for PAT xlates (30 seconds).
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
Gateway IP host-pc-2
Transaction ID 2052
Endpoint name aaln/1
Call ID 9876543210abcdef
