hello,
my topology is: cisco --> 3COM 4210-48port --> router. Problem is, that cisco know mac of the router , but 4210 dont. And then all of the traffic, which is for the router, 4210 resending to other ports, because dont know about mac of the router. There is only about 800 macs learned on the switch.
I try this on another switch 4210 with different fw version, but the problem didnt solved.
do you have any idea, where could be a problem?
thanks for your reply
