Unidirectional Link Detection Configuration
This chapter shows a complete configuration to enable UDLD in a simple network topology.
The purpose of Unidirectional Link Detection protocol (UDLD) is to monitor the physical links and detect when a unidirectional link exists. Upon detection user can either block the port or notify the link status based on the network administrator's configuration.
UDLD works in two different modes:
• Normal mode
• Aggressive mode
