We've got an Ethernet router (2911) that's taking errors on Gi0/0, which is connected to an encryptor. The errors are dot3StatsInternalMacReceiveErrors The description I'm finding by Googling isn't helping a whole lot... "A count of frames for which reception on a particular interface fails due to an internal MAC sublayer receive error." Any input on what's likely to produce this sort of error? If more info would be useful, a clue as to how to dig it out from SNMP would be helpful, as I don't have console access to this, and the only people who do are the ones who have, over the past several months; replaced the router, thought the encryptor might be "sending data too fast for the router to handle", and are now telling us that moving to a 6509 will surely fix the problem. Yes, I have a couple of big forehead-shaped dents in my desk :-/
