Do you have udld turned on? What does the log show?
My 2950/3550 gbic ports do that when the gbic goes bad or I get a UDLD
error. Never seen it on a faste before.

not
working or cable is unplugged, ususally it will be UP

Any idea ? The switch is 2950G.

switchport access vlan 22
switchport mode access
no ip address
duplex full
