How do I configure UDLD (Unidirectional Link Detection) in the NVT Phybridge CLEER24-10G (NV-CLR-024-10G) switch?

Unidirectional Link Detection (UDLD) is one of the several loop prevention mechanisms contained on the CLEER24-10G. UDLD is configured at the interface level and is used to detect unidirectional links between switches. For a successful UDLD configuration, both the local and remote switch must be UDLD enabled.

There are two UDLD modes:

• Normal Mode
• Aggressive Mode

CLEER24-10G# configure terminal
CLEER24-10G(config)# udld aggressive
CLEER24-10G(config)# udld message time-interval 15
CLEER24-10G(config)# interface GigabitEthernet 1/1
CLEER24-10G(config-if)# udld port aggressive message time-interval 10
CLEER24-10G(config-if)# end
CLEER24-10G#copy running-config startup-config

Refer to the Admin Guide for all the advanced settings available in the switch. You’ll find additional resources like the Datasheet, Admin Guide, A&E spec sheet, etc on the product page here.
