I would like to set the MTU on all the eth interfaces to 4000. I don't think this can be done per port by simply doing MTU 4000. I believe I have to set up a policy and class map to do this now then apply that map to an individual interface. I need assistance with this. i need something simple to just set the mtu size. not worried about bandwidth, priority or the like. i want this applied to both incoming and outgoing traffic.
