udld port [slot/port[-port2]] mode {normal | aggressive}
Syntax Definitions
slot/port The slot number for the module and the physical port number on that
module (e.g., 3/1 specifies port 1 on slot 3).
port2 The last port number in a range of ports that you want to configure on
the same slot (e.g, 3/1-4 specifies ports 1-4 on slot 3).

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.
