MGCP Inspection
Create a class map or modify an existing class map to identify MGCP traffic. Use the class-map
Step 2
command to do so, as follows.
hostname(config)# class-map class_map_name
hostname(config-cmap)#
where class_map_name is the name of the traffic class. When you enter the class-map command, the
CLI enters class map configuration mode.
Use a match access-list command to identify MGCP traffic with the access list you created in
Step 3
hostname(config-cmap)# match access-list acl-name
(Optional) If the network has multiple call agents and gateways for which the FWSM has to open
Step 4
pinholes, create an MGCP map. To do so, perform the following steps.
Create an MGCP map by using the mgcp-map command. The mgcp-map command lets you create
a.
parameters for MGCP inspection. Use the mgcp-map command as follows.
hostname(config-cmap)# mgcp-map map_name
hostname(config-mgcp-map)#
where map_name is the name of the MGCP map. The system enters MGCP map configuration mode
and the CLI prompt changes accordingly.
Configure the call agents. To do so, use the call-agent command once per call agent, as follows.
b.
hostname(config-mgcp-map)# call-agent ip_address group_id
Configure the gateways. To do so, use the gateway command once per gateway, as follows.
c.
hostname(config-mgcp-map)# gateway ip_address group_id
d. (Optional) If you want to change the maximum number of commands allowed in the MGCP
command queue, use the command-queue command, as follows:
hostname(config-mgcp-map)# command-queue command_limit
Create a policy map or modify an existing policy map that you want to use to apply the MGCP inspection
Step 5
engine to MGCP traffic. To do so, use the policy-map command, as follows.
hostname(config-cmap)# policy-map policy_map_name
hostname(config-pmap)#
where policy_map_name is the name of the policy map. The CLI enters the policy map configuration
mode and the prompt changes accordingly.
Specify the class map, created in
Step 6
so, as follows.
hostname(config-pmap)# class class_map_name
hostname(config-pmap-c)#
where class_map_name is the name of the class map you created in
map class configuration mode and the prompt changes accordingly.
Step 7 Enable MGCP application inspection. To do so, use the inspect mgcp command, as follows.
hostname(config-pmap-c)# inspect mgcp [map_name]
hostname(config-pmap-c)#
where map_name is the MGCP map that you may have created in optional
Use the service-policy command to apply the policy map globally or to a specific interface, as follows:
