4.35 UDLD Port Configuration

This page allows the user to inspect the current UDLD configurations, and possibly change them as well.

Figure 4-126. UDLD Port Configuration

The UDLD Port Configuration page has the following parameters:

  • 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 this mode, UDLD functionality doesn't exists on port.
    • Normal: In this mode, if the link state of the port was determined to be unidirectional, it will not affect the port state.
    • Aggressive: In this mode, unidirectional detected ports will get shutdown. To bring back the ports up, need to disable UDLD on that port.
  • Message Interval: Configures the period of time between UDLD probe messages on ports that are in the advertisement phase and are determined to be bidirectional. The range is from 7 to 90 seconds (Default value is 7 seconds) (Currently default time interval is supported, due to lack of detailed information in RFC 5171).
