Problem Desc :Port Fa0/1 on Cisco 1841 rtr is not functioning.
Observation : Line protocol on the interface always stays up irrespective of any device is connected to it or NO
No mac address is learnt.
We tried connecting devices to this port viz different working straight
cables to the Cisco 2960 Switch in branch and cross cables to laptop.
The port was functional before as we had a TATA MPLS Ethernet link on this
interface.
Rtr was also restarted and checked.
