Displaying Summary UDLD Information. To display summary information on all UDLD-enabled ports, enter the show link-keepalivecommand. For example:

ProCurve(config)# show link-keepalive
Total link-keepalive enabled ports: 4
Keepalive Retries: 3			Keepalive Interval: 1 sec
Port Enabled		Physical	Keepalive	Adjacent		UDLD	Port 1 is UDLD-enabled, and
							tagged for a specific VLAN.
		Status	Status	Switch		VLAN

-------------------------------------------------------------------
1	Yes	up	up	00d9d-f9b700		200
2	Yes	up	up	01560-7b1600		Port 3 is UDLD-enabled, but
						has no physical connection.

5	No	down	off-line		Port 4 is connected, but is blocked
					due to a link-keepalive failure

Port 5 has been disabled by the System Administrator.
