Situation Description

Key exchange messages used to negotiate Internet Key Exchange (IKE) tunnels have been retransmitted by the local security endpoint.

 

Suggested Actions

This situation is an indication of a networking problem or a configuration mismatch problem. Evaluate the UNIX syslog and identify the reason for the IKE daemon dropping messages.

This warning situation uses the CHANGE function and the IKE Total Retransmitted Key Messages attribute to determine if the total number of retransmitted key messages was more than five for three consecutive evaluations for the situation. During IKE tunnel negotiation the IKE daemon retransmits 10 messages before declaring a failed activation attempt. Key messages will be retransmitted periodically for an activation attempt. The five retransmitted messages may or may not be for the same activation attempt. 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.
