IKE phase-1 negotiation is failed as initiator, aggressive mode.

L0 Member

Hi All,

We are facing an issue where IKE phase-1 negotiation has failed as the initiator in aggressive mode. The SA (Security Association) has failed between 199.X.X.X [500] and 162.X.X.X [500], with the cookie: fa14dad50518163e:0000000000. Can someone else please assist me in resolving this?

to troubleshoot phase1 it's ideal if you have access to the logs of the receiving end, as the initiator will have very minimal logging available

if you can't access the remote side, see if they are able to initiate a connection so you can see which part in the negotiation fails

most likely it's a problem with the ID or the available cipher pairs between the two peers
