Failure Detection Pair configuration

Use these commands to configure a Failure Detection Pair, which consists of one Link to Monitor (LtM) and one Link to Disable (LtD). When the switch detects a failure on the LtM, it automatically disables the ports in the LtD.

The following table describes the Failure Detection Pair (FDP) configuration commands.

Configuration Dump

The dump program writes the current switch configuration to the terminal screen. To start the dump program, at the prompt, enter:

Switch(config)# show running-config

The configuration is displayed with parameters that have been changed from the default values. The screen display can be captured, edited, and placed in a script file, which can be used to configure other switches. Paste the configuration commands from the script file at the command line prompt of the switch. The active configuration can also be saved or loaded via TFTP.
