Hello,

do you see any errors on the port of the 2950 where the modem is connected to ? Can you post the output of 'show interfaces FastEthernet' of the port in question ?

Regards,

Hi,

Seema to be a auto-negotiation issue. Check whether the device connected to switch port supports which speed 10/100 and also the duplex full/half. Try to Hardset the speed and duplex on the switch port and the other device port,
