4.3.12 UDLD
Unidirectional Link Detection (UDLD) is a data link layer protocol from Cisco Systems to monitor the physical configuration of
the cables and detect unidirectional links. UDLD complements the Spanning Tree Protocol which is used to eliminate switching
loops..
4.3.12.1 UDLD Port Configuration
This page allows the user to inspect the current UDLDconfigurations, and possibly change them as well. as screen in Figure
4-3-12-1 appears.
Figure 4-3-12-1: UDLD Configuration Page Screenshot
The page includes the following fields:
General Settings
Object Description
Port Port number of the switch.
UDLD Mode Configures the UDLD mode on a port. Valid values are Disable, Normal and
Aggressive. Default mode is Disable.
Disable: In disabled mode, UDLD functionality doesn't exists on port..
Normal: In normal mode, if the link state of the port was determined to be
unidirectional, it will not affect the port state.
