Chapter 22 Applying Application Layer Protocol Inspection H.323 Inspection Example 22-8 Configuring H.323 Inspection without an H.225 Map 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 1718 hostname(config)# access-list h323_acl permit udp any any eq 1719 hostname(config)# access-list h323_acl permit tcp any any eq 1720 hostname(config)# class-map h323-traffic hostname(config-cmap)# match access-list h323_acl hostname(config-cmap)# policy-map sample_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)# service-policy sample_policy interface outside hostname(config)# Example 22-9 includes an H.225 map with two HSI groups, as part of the overall H.323 configuration. Example 22-9 Configuring H.323 Inspection with an H.225 Map hostname(config)# access-list h323_acl permit udp any any eq 1718 hostname(config)# access-list h323_acl permit udp any any eq 1719 hostname(config)# access-list h323_acl permit tcp any any eq 1720 hostname(config)# class-map h323-traffic hostname(config-cmap)# match access-list h323_acl hostname(config-cmap)# h225-map sample_map hostname(config-h225-map)# hsi-group 1 hostname(config-h225-map-hsi-grp)# hsi 10.10.15.11 hostname(config-h225-map-hsi-grp)# endpoint 10.3.6.1 inside hostname(config-h225-map-hsi-grp)# endpoint 10.10.25.5 outside hostname(config-h225-map-hsi-grp)# policy-map sample_policy hostname(config-pmap)# class h323_port hostname(config-pmap-c)# inspect h323 ras hostname(config-pmap-c)# inspect h323 h225 sample_map hostname(config-pmap-c)# service-policy sample_policy interface outside hostname(config)# Configuring H.323 and H.225 Timeout Values To configure the idle time after which an H.225 signalling connection is closed, use the timeout h225 command. The default for H.225 timeout is one hour. To configure the idle time after which an H.323 control connection is closed, use the timeout h323 command. The default is five minutes. Verifying and Monitoring H.323 Inspection This section describes how to display information about H.323 sessions. This section includes the following topics: • Monitoring H.225 Sessions, page 22-54 • Monitoring H.245 Sessions, page 22-54 • Monitoring H.323 RAS Sessions, page 22-55 OL-20748-01 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM 22-53
