Is there auto-negotiation when you connect a router FaX/X to a switch interface? I know how to check if speed and duplex are auto in a Switch... how can you see this in a router (command)?
hi, from your question, i believe to use the follwing command to know either auto-nego or not:
"show run int fax/x" to see the configuration of a particular interface. If you do not see Speed 100 and duple-full, then your port is auto-nego.
