%CRYPTO-6-IKMP_MODE_FAILURE: Processing of Informational mode failed with p

[vyelmene]

Has anyone ran across this error message: %CRYPTO-6-IKMP_MODE_FAILURE: Processing of Informational mode failed with peer at x.x.x.x? I've seen similar ones, but not the 'informational' mode. I'm also getting this message; ISAKMP (1): sending packet to x.x.x.x (I) MM_NO_STATE.

Any help would be great.

Thanks.

Hi Everyone,

thanks for the feedback on the fix. I was experiencing the same error and the fix was a mismatch in the crypto isakmp policy. In my case on ecryption, one end had "aes" and the other "aes 256". Once I corrected that, packets are being encrypted now and message cleared out.
