discovered unknown dhcp server

Wed Dec 27, 2006 3:40 pm

The error message below is from the log file of a Router OS 2.9.38 router with a DCHP relay configured to identify the dhcp server.

What am I missing?

REDUX: Re: discovered unknown dhcp server

Does anyone know what the cockpit error is; the IP address at which ROS says it found a rogue server is the IP address in the dhcp-relay statement.

Well, a lot indeed, but in this particular case, the mac address called out in the dhcp-alert code.
