Cisco Systems ASA 5500 Manual De Usuario

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.

With the access list you created in 

, use a match access-list command to identify the traffic to be 

scanned:

hostname(config-cmap)# match access-list acl-name

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.

Specify the class map, created in 

, 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 

. The CLI enters the policy 

map class configuration mode and the prompt changes accordingly.

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 

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 

. 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
