The section includes the following topics:

Configuring the UDLD Mode

You can configure normal or aggressive unidirectional link detection (UDLD) modes for Ethernet interfaces
on devices configured to run UDLD. Before you can enable a UDLD mode for an interface, you must make
sure that UDLD is already enabled on the device that includes the interface. UDLD must also be enabled on
the other linked interface and its device.
To use the normal UDLD mode, you must configure one of the ports for normal mode and configure the other
port for the normal or aggressive mode. To use the aggressive UDLD mode, you must configure both ports
for the aggressive mode.
Note
Before you begin, UDLD must be enabled for the other linked port and its device.
