Fixed In:
14.0.0

Opened: Nov 06, 2017
Severity: 3-Major

Symptoms

An unnecessary and distracting log line appears in /var/log/ltm when a IKEv1 security association is negotiated: No need for ISAKMP mode config. This is an internal mechanism related to dynamic IP address allocation at negotiation time, which the BIG-IP system does not support.

Impact

No impact beyond the message in /var/log/ltm for each SA negotiated.

Conditions

When a remote peer is configured for IKEv1.

Workaround

None.

Fix Information

IKEv1 no longer sends the event involved, because the system does not depend on this event.
