I have two 6509-E switches using portcahnnel. The second switch continues to learn all zero mac and sends it out to some of my access switches. The only sniffer captures I can find show up as Fiber Channel Protocol. Has anyone seen this? Cisco TA...
Thank You for your reply. All sniffer traces show all zero mac src and dest. And shows as Fiber Channel Protocol. I will send you some of the items you asked for later today.
