Description: A security association is a set of parameters that determine how two or more routers use security services. A security association bundles an authentication algorithm, start time, expiration time, authentication key, and IS-IS level and associates these parameters with a security key ID.

Use the start-time now command to immediately activate this security association.

Use the start-time hh:mm:ss day month year command to configure the activation time and date for this security association.

Factory Default: None.

Command Mode: Security configuration.

Example: In the following example:

The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration.

The security 1 level-1 command specifies a security association (1), the level of the association, and changes the command mode to Security configuration.

The authentication hmac-md5 configures the type of authentication used by this security association to HMAC-MD5 for this security association with an authentication key of sa-Key1:

The start-time command configures the start time for this security association at noon on November 30, 2001.

The end-time command configures the end time for this security association as noon on December 10, 2001,

The show isis security-association ID command displays the association:

router#router isis 10

router(config-router)#security 1 level-1

router(config-security)#authentication hmac-md5 sa-Key1

router(config-security)#start-time 12:00 november 20 2001

router(config-security)#end-time 12:00 december 10 2001

router(config-security)#end

router#show isis security-association 1
