Andreas,

Normally, a cisco router will check for aggressive-mode during boot or responding to an IKE request which is what it appears to be with the information you have provided. How often does this message appear? every few minutes or only at initialisation stage? it could just mean that there are some peers trying to connect via IPSEC to your router.

Andreas,

Have a read of the below support page, depending on your environment setup you may be able to get away with adding the host as a peer to stop the informational logs.

Do you know which peers are trying to communicate over IPSec to your router?
