Chapter 21 Applying Application Layer Protocol Inspection

Managing H.323 Inspection

For example, the following command assigns the h323_port traffic class to the current policy map.

hostname(config-pmap)# class h323_port

The CLI enters the policy map class configuration mode and the prompt changes accordingly, as follows:

hostname(config-pmap-c)#

Step 5 To enable H.323 traffic inspection, enter the following commands:

hostname(config-pmap-c)# inspect h323 ras

hostname(config-pmap-c)# inspect h323 h225

Return to policy map configuration mode by entering the following command:

hostname(config-pmap-c)# exit

hostname(config-pmap)#

Step 6 Return to global configuration mode by entering the following command:

hostname(config-pmap)# exit

hostname(config)#

Step 7 Apply the policy map globally or to a specific interface by entering the following command:

hostname(config)# service-policy

policy_map_name

[global | interface

interface_ID

Replace policy_map_name with the policy map you configured in Step 5, and identify all the interfaces

with the global option or a specific interface using the name assigned with the name-if command.

For example, the following command applies the inbound_policy to the outside interface:

hostname(config)# service-policy inbound_policy interface outside

The following command applies the inbound_policy to all the security appliance interfaces:

hostname(config)# service-policy inbound_policy global

Example 21-4 Enabling and Configuring H.323 Inspection

You enable the H.323 inspection engine as shown in the following example, which creates a class map

to match H.323 traffic on the default port (1720). The service policy is then applied to the outside

interface.

hostname(config)# access-list h323_acl permit udp any any eq 1720

hostname(config)# access-list h323_acl permit udp any any eq 1721

hostname(config)# class-map h323-traffic

hostname(config-cmap)# match access-list h323_acl

hostname(config-cmap)# exit

hostname(config)# policy-map inbound_policy

hostname(config-pmap)# class h323_port

hostname(config-pmap-c)# inspect h323 ras

hostname(config-pmap-c)# inspect h323 h225

hostname(config-pmap-c)# exit

hostname(config)# service-policy inbound_policy interface outside

To enable H.323 inspection for all interfaces, enter the global parameter in place of interface outside.
