Chapter 22 Applying Application Layer Protocol Inspection HTTP Inspection Step 5 Step 6 Step 7 hostname(config-pmap)# Where the policy_map_name is the name of the policy map. The CLI enters policy-map configuration mode. (Optional) To add a description to the policy map, enter the following command: hostname(config-pmap)# description string To apply actions to matching traffic, perform the following steps. a. Specify the traffic on which you want to perform actions using one of the following methods: • Specify the HTTP class map that you created in Step 3 by entering the following command: hostname(config-pmap)# class class_map_name hostname(config-pmap-c)# • Specify traffic directly in the policy map using one of the match commands described in Step 3. If you use a match not command, then any traffic that does not match the criterion in the match not command has the action applied. b. Specify the action you want to perform on the matching traffic by entering the following command: hostname(config-pmap-c)# {[drop-connection [send-protocol-error]| reset] [log]} Not all options are available for each match or class command. See the CLI help or the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Command Reference for the exact options available. The drop-connection keyword drops the packet and closes the connection. The reset keyword drops the packet, closes the connection, and sends a TCP reset to the server and/or client. The log keyword, which you can use alone or with one of the other keywords, sends a system log message. You can specify multiple class or match commands in the policy map. For information about the order of class and match commands, see the "Defining Actions in an Inspection Policy Map" section on page 20-7. To configure parameters that affect the inspection engine, perform the following steps: a. To enter parameters configuration mode, enter the following command: hostname(config-pmap)# parameters hostname(config-pmap-p)# b. To check for HTTP protocol violations, enter the following command: hostname(config-pmap-p)# protocol-violation [action [drop-connection | reset | log]] Where the drop-connection action closes the connection. The reset action closes the connection and sends a TCP reset to the client. The log action sends a system log message when this policy map matches traffic. c. To enforce banner obfuscation, enter the following command: hostname(config-pmap-p)# mask-banner The mask-banner command is the default when policy-map type inspect is configured, however no mask-banner can be entered to change the default. d. To substitute a string for the server header field, enter the following command: hostname(config-pmap-p)# spoof-server string OL-20748-01 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM 22-63
