I have a problem.

When I connect somethings to ports such as a pc, a sever, a swich and a router, their MAC address are not appear on the ports.

As a matter of course, I adjusted the speed and duplex each other.

Empty ports have the same problem without used ports.


What should I do ?

RT#sh mac-address-table interface fastEthernet 13/1

Legend: * - primary entry

age - seconds since last seen

n/a - not available


vlan mac address type learn age ports

- Are you having the same problem is you connect one of those PCs to a port on the WS-X6248-RJ-45 module?

- Under the show int f13/1, do you see an increasing input packet count? any errors?

- Is the STP state FWD, use sh spann int f13/1 ?

Hi, jbrenesj

I am really appreciate your help.


- Are you having the same problem is you connect one of those PCs to a port on the WS-X6248-RJ-45 module?

-> Yes, all empty(notconnect) ports except that ports is already in use by user have the same problem.


- Under the show int f13/1, do you see an increasing input packet count? any errors?

-> Input packet count and any errors are always "0".


- Is the STP state FWD, use sh spann int f13/1 ?

-> The STP state is FWD.


What do you think of this problem ?
