Clearing Udld Statistics - HP ProCurve 9304M Installation And Configuration Manual

The show interface ethernet <portnum> command also displays the UDLD state for an individual port. In
addition, the line protocol state listed in the first line will say "down" if UDLD has brought the port down. Here is an
example:
HP9300(config)# show interface ethernet 1/1
FastEthernet1/1 is down, line protocol is down, link keepalive is enabled
Hardware is FastEthernet, address is 00e0.52a9.bbca (bia 00e0.52a9.bbca)
Configured speed auto, actual unknown, configured duplex fdx, actual unknown
Member of L2 VLAN ID 1, port is untagged, port state is DISABLED
STP configured to ON, priority is level0, flow control enabled

Not member of any configured trunks
No port name
300 second input rate: 0 bits/sec, 0 packets/sec, 0.00% utilization
300 second output rate: 0 bits/sec, 0 packets/sec, 0.00% utilization
0 packets input, 0 bytes, 0 no buffer
