Chapter 22 Applying Application Layer Protocol Inspection H.323 Inspection Table 22-5 Command hsi-group hsi endpoint H.225 Configuration Commands Configuration mode H.225 map configuration mode HSI group configuration mode HSI group configuration mode Description Defines an HSI group and enables HSI group configuration mode. Each HSI group can contain a maximum of ten endpoints. Identifies the HSI. Identifies one or more endpoints within the HSI group. Enabling and Configuring H.323 Inspection H.323 inspection is enabled by default. To enable H.323 inspection, including the optional use of an H.225 map, perform the following steps: Step 1 Step 2 Step 3 Step 4 To define an access list with ACEs that identify the ports required for H.323 traffic, enter the following command for each ACE: hostname(config)# access-list acl-name permit {udp | tcp} any any eq port where acl-name is the name you assign to the access list and port is the H.323 port that the ACE identifies. The standard ports are UDP ports 1718 and 1719 and TCP port 1720. Create a class map or modify an existing class map to identify H.323 traffic. Use the class-map 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 H.323 traffic with the access list you created in Step 1. hostname(config-cmap)# match access-list acl-name (Optional) If required by your network topology, configure an H.225 map. For more information about whether your network requires an H.225 map, see the "Topologies Requiring H.225 Configuration" section on page 22-50. To create and configure an H.225 map, perform the following steps. a. Create an H.225 map. hostname(config)# h225-map map_name hostname(config-h225-map)# The system enters H.225 map configuration mode and the CLI prompt changes accordingly. b. Identify an HSI group. To do so, use the hsi-group command, as follows. hostname(config-h225-map)# hsi-group group_ID hostname(config-h225-map-hsi-grp)# where group_ID is a number, from 0 to 2147483647, that identifies the HSI group.
