I am trying to connect a 3com switch to our Cisco 3750 stack, however when I connect it to the switchport on the Cisco stack it goes into err-disabled mode.
After a little investigation I found that this was becasue the bpduguard and portfast had been enbaled on the switchport. However I would like your advise as to what to do next? should I remove the BPDU Guard feature from this switchport, if so what are the implications?
Thanks for your help
