BFD Detection Result Affects Forwarding on an Interface
Procedure
- Run the display interface interface-type interface-number command to check the physical status of the interface bound to the BFD session.
If the value of Line protocol current state is UP (BFD status down), the interface status is affected by the BFD session status. When the BFD session detects a link fault, the interface enters the BFD status down state. Go to step 2.
If the value of Line protocol current state is UP but the interface cannot forward packets, the forwarding module is working properly.
- Run the display bfd session all command to check the BFD session status.
If the BFD session status is Down, go to step 3.
- Run the display current-configuration configuration bfd-session command to check the BFD session
configuration and check whether the process-interface-status command is used.
If the process-interface-status command is used, the interface enters the DOWN (BFD status down) state when the BFD session detects a link fault and enters the Down state. As a result, the interface cannot forward packets.
