Usage Guidelines

Usage Scenario

The display bfd statistics session command displays BFD session statistics.

Precautions

  • If a static BFD session with automatically negotiated discriminators and a dynamic BFD session are bound to the same peer IP address, the display bfd statistics session command displays the same entry for the static BFD session or dynamic BFD session.
  • Before using the display bfd statistics session command to view BFD session statistics, run the reset bfd statistics command to clear existing statistics.

Example

# Display statistics on all BFD sessions.
