Chapter 22 Applying Application Layer Protocol Inspection DCERPC Inspection Configuring a DCERPC Inspection Policy Map for Additional Inspection Control To specify additional DCERPC inspection parameters, create a DCERPC inspection policy map. You can then apply the inspection policy map when you enable DCERPC inspection according to the "Configuring Application Inspection" section on page 22-6. To create a DCERPC inspection policy map, perform the following steps: Step 1 Step 2 Step 3 Create a DCERPC inspection policy map, enter the following command: hostname(config)# policy-map type inspect dcerpc policy_map_name 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 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 configure the timeout for DCERPC pinholes and override the global system pinhole timeout of two minutes, enter the following command: hostname(config-pmap-p)# timeout pinhole hh:mm:ss Where the hh:mm:ss argument is the timeout for pinhole connections. Value is between 0:0:1 and 1193:0:0. c. To configure options for the endpoint mapper traffic, enter the following command: hostname(config-pmap-p)# endpoint-mapper [epm-service-only] [lookup-operation [timeout hh:mm:ss]] Where the hh:mm:ss argument is the timeout for pinholes generated from the lookup operation. If no timeout is configured for the lookup operation, the timeout pinhole command or the default is used. The epm-service-only keyword enforces endpoint mapper service during binding so that only its service traffic is processed. The lookup-operation keyword enables the lookup operation of the endpoint mapper service. The following example shows how to define a DCERPC inspection policy map with the timeout configured for DCERPC pinholes. hostname(config)# policy-map type inspect dcerpc dcerpc_map hostname(config-pmap)# timeout pinhole 0:10:00 hostname(config)# class-map dcerpc hostname(config-cmap)# match port tcp eq 135 hostname(config)# policy-map global-policy hostname(config-pmap)# class dcerpc hostname(config-pmap-c)# inspect dcerpc dcerpc-map hostname(config)# service-policy global-policy global OL-20748-01 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM 22-17
