Configuration Warnings and Event Log Messages

Warning Messages. The following table shows the warning messages that may be issued and their possible causes, when UDLD is configured for tagged ports.

Table 6. Warning Messages caused by configuring UDLD for Tagged Ports

CLI Command Example Warning Message Possible Problem

link-keepalive 6	Possible configuration
	problem detected on port
	6.	UDLD VLAN
	configuration does not
	match the port's VLAN
	configuration.
link-keepalive 7	Possible configuration
vlan 4	problem detected on port
	7.	UDLD VLAN
	configuration does not
	match the port's VLAN
	configuration.

You have attempted to enable UDLD on a port that is a tagged only port, but did not specify a configuration for tagged UDLD control packets. In this example, the switch will send and receive the UDLD control packets untagged despite issuing this warning.

You have attempted to configure tagged UDLD packets on a port that does not belong to the specified VLAN. In this example, if port 7 belongs to VLAN 1 and 22, but the user tries to configure UDLD on port 7 to send tagged packets in VLAN 4, the configuration will be accepted. The UDLD control packets will be sent tagged in VLAN 4, which may result in the port being blocked by UDLD if the user does not configure VLAN 4 on this port.

no vlan 22 tagged	Possible configuration
20	problem detected on port
	18. UDLD VLAN
	configuration does not
	match the port's VLAN
	configuration.

You have attempted to remove a VLAN on port that is configured for tagged UDLD packets on that VLAN. In this example, if port 18, 19, and 20 are transmitting and receiving tagged UDLD packets for Vlan 22, but the user tries to remove Vlan 22 on port 20, the configuration will be accepted. In this case, the UDLD packets will still be sent on Vlan 20, which may result in the port being blocked by UDLD if the users do not change the UDLD configuration on this port.

Note: If you are configuring the switch via SNMP with the same problematic VLAN configuration choices, the above warning messages will also be logged in the switch’s event log.

Event Log Messages. The following table shows the event log messages that may be generated once UDLD has been enabled on a port.
