Displaying BFD Information

Various show commands can display statistical information about BFD configurations.
Use one or more of the following commands to verify BFD information. Using these commands is optional, and the variations of the commands can be entered in any order. For full documentation of all the show commands for BFD, refer to the RUCKUS FastIron Command Reference.
  1. Enter the show bfd command to display general BFD information. 
    device> show bfd
