Managing the CSC SSM
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
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 CSC
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
Step 5
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
map class configuration mode and the prompt changes accordingly.
Step 6 If you want to enforce a per-client limit for simultaneous connections that the adaptive security appliance
diverts to the CSC SSM, use the set connection command, as follows:
hostname(config-pmap-c)# set connection per-client-max n
where n is the maximum simultaneous connections the adaptive security appliance will allow per client.
This prevents a single client from abusing the services of the CSC SSM or any server protected by the
SSM, including prevention of attempts at DoS attacks on HTTP, FTP, POP3, or SMTP servers that the
CSC SSM protects.
Assign the traffic identified by the class map as traffic to be sent to the CSC SSM. Use the csc command
Step 7
to do so, as follows.
hostname(config-pmap-c)# csc {fail-close | fail-open}
The fail-close and fail-open keywords control how the adaptive security appliance treats traffic when
the CSC SSM is unavailable. For more information about the operating modes and failure behavior, see
the "About the CSC SSM" section on page
Use the service-policy command to apply the policy map globally or to a specific interface, as follows:
Step 8
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
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 CSC SSM as specified.
