Chapter 19 Managing the AIP SSM and CSC SSM
Managing the AIP SSM
Step 2 Create a class map to identify the traffic that should be diverted to the AIP SSM. 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.
Step 3 With the access list you created in Step 1, use a match access-list command to identify the traffic to be
scanned:
hostname(config-cmap)# match access-list acl-name
Step 4 Create a policy map or modify an existing policy map that you want to use to send traffic to the AIP
SSM. To do so, use the policy-map command, as follows.
hostname(config-cmap)# policy-map policy_map_name
hostname(config-pmap)#
where policy_map_name is the name of the policy map. The CLI enters the policy map configuration
mode and the prompt changes accordingly.
Step 5 Specify the class map, created in Step 2, that identifies the traffic to be scanned. Use the class command
to do so, as follows.
hostname(config-pmap)# class class_map_name
hostname(config-pmap-c)#
where class_map_name is the name of the class map you created in Step 2. The CLI enters the policy
map class configuration mode and the prompt changes accordingly.
Step 6 Assign the traffic identified by the class map as traffic to be sent to the AIP SSM. Use the ips command
to do so, as follows.
hostname(config-pmap-c)# ips {inline | promiscuous} {fail-close | fail-open}
The inline and promiscuous keywords control the operating mode of the AIP SSM. The fail-close and
fail-open keywords control how the adaptive security appliance treats traffic when the AIP SSM is
unavailable. For more information about the operating modes and failure behavior, see the “About the
AIP SSM” section on page 19-1.
Step 7 Use the service-policy command to apply the policy map globally or to a specific interface, as follows:
hostname(config-pmap-c)# service-policy policy_map_name [global | interface interface_ID]
hostname(config)#
where policy_map_name is the policy map you configured in Step 4. If you want to apply the policy map
to traffic on all the interfaces, use the global keyword. If you want to apply the policy map to traffic on
a specific interface, use the interface interface_ID option, where interface_ID is the name assigned to
the interface with the nameif command.
Only one global policy is allowed. You can override the global policy on an interface by applying a
service policy to that interface. You can only apply one policy map to each interface.
The adaptive security appliance begins diverting traffic to the AIP SSM as specified.
The following example diverts all IP traffic to the AIP SSM in promiscuous mode, and blocks all IP
traffic should the AIP SSM card fail for any reason:
hostname(config)# access-list IPS permit ip any any
hostname(config)# class-map my-ips-class
