Cisco Systems C7200 Monitoring and Maintaining IPSec, Applying Crypto Map Sets to Interfaces

Chapter 4 Configuring the VSA

Configuration Tasks

To add a dynamic crypto map set into a crypto map set, use the following command in global configuration mode:

Command	Purpose
Router(config)# crypto map map-nameseq-num	Adds a dynamic crypto map set to a static crypto
ipsec-isakmp dynamic dynamic-map-name	map set.

Applying Crypto Map Sets to Interfaces

Apply a crypto map set to each interface through which IPSec traffic will flow. Crypto maps instruct the router to evaluate the interface traffic against the crypto map set and use the specified policy during connection or security association negotiation on behalf of traffic to be protected by crypto.

To apply a crypto map set to an interface, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)# crypto map map-name	Applies a crypto map set to an interface.

To specify redundant interfaces and name an identifying interface, use the following command in global configuration mode:

Command	Purpose
Router(config)# crypto map map-name	Permits redundant interfaces to share the same
local-address interface-id	crypto map, using the same local identity.

Monitoring and Maintaining IPSec

To clear (and reinitialize) IPSec security associations, use one of the following commands in EXEC or enable mode (see “Using the EXEC Command Interpreter” section on page 4-2for more details):

Command	Purpose
Router# clear crypto sa	Clears IPSec security associations.
or	Note Using the clear crypto sa command without parameters
	will clear out the full SA database, which will clear out
Router# clear crypto sa counters
	active security sessions. You may also specify the peer,
or	map, or spi keywords to clear out only a subset of the SA
	database. For more information, see the clear crypto sa
Router# clear crypto sa peer {ip-address
	command.
peer-name}
or
Router# clear crypto sa map map-name
or
Router# clear crypto sa spi destination-address
