Chapter 21 Applying Application Layer Protocol Inspection

Managing CTIQBE Inspection

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

hostname(config-pmap)#

Step 4 Specify the traffic class defined in Step 2 to be included in the policy map by entering the following

command:

hostname(config-pmap)# class

class_map_name

For example, the following command assigns the ctiqbe_port traffic class to the current policy map:

hostname(config-pmap)# class ctiqbe_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 CTIQBE application inspection, enter the following command:

hostname(config-pmap-c)# inspect ctiqbe

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

hostname(config-pmap-c)# exit

hostname(config-pmap)#

Step 7 Return to global configuration mode by entering the following command:

hostname(config-pmap)# exit

hostname(config)#

Step 8 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 the all the security appliance interfaces:

hostname(config)# service-policy inbound_policy global

Example 21-1 Enabling and Configuring CTIQBE Inspection

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

to match CTIQBE traffic on the default port (2748). The service policy is then applied to the outside

interface.

hostname(config)# class-map ctiqbe_port

hostname(config-cmap)# match port tcp eq 2748

hostname(config-cmap)# exit

hostname(config)# policy-map inbound_policy

hostname(config-pmap)# class ctiqbe_port

hostname(config-pmap-c)# inspect ctiqbe

hostname(config-pmap-c)# exit

hostname(config)# service-policy inbound_policy interface outside

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