Re: %CRYPTO-6-IKMP_MODE_FAILURE: Processing of Informational mod

Hi Ahmed

As pe rthe supporting doc its mainly because of the negotiations failure between the peers.

You need to check out the IKE and IPSEC parameters on both the peers and make sure you have the same parameters/keys defined..

%CRYPTO-6-IKMP_MODE_FAILURE: Processing of [chars] mode failed with peer at [IP_address]

Negotiation with the remote peer has failed.

Recommended Action: If this situation persists, contact the remote peer.

Also you can refer these links for more info on the same..
