Re: IKMP_MODE_FAILURE Error Log

Hi Prem,

%CRYPTO-4-IKMP_NO_SA: IKE message from [IP-address] has no SA and is not an initialization offer

IKE maintains the current state for a communication in the form of security associations. No security association exists for the specified packet, and it is not an initial offer from the peer to establish one. This situation could be a denial-of-service attack. Contact the remote peer or the administrator of the remote peer.
