Usage Guidelines

The UDLD protocol must be enabled before using this command.

The UDLD protocol is not supported on aggregate ports.

When two UDLD enabled ports that are configured in aggressive mode of operation gets the link-up

asynchonously, then the UDLD port which gets the link-up indication first is considered to be in the

shutdown state. In such case, the link should be configured manually after both the links are up to start

UDLD detection.

In case of faulty cable connection, the port which is configured in normal mode of operation is deter-

mined to be in the shutdown state.
