This condition can occur either because of an Internet Security Association
and Key Management Protocol (ISAKMP) error (check the service levels on both
peers) or, when using shared keys, if the shared keys on the peers do not match.
This warning situation uses the CHANGE function and the IKE Total Invalid Key Messages
attribute to determine if the total number of invalid key messages has increased since the situation
was last evaluated. An attribute is not highlighted when the CHANGE function is used,
and the Current Situation Value Table may not display data. By default, this
situation is evaluated every 15 minutes and is not run at startup.
