Configuring Association Between a BFD Session and an Interface to Trigger the Associated Interface in Down State

Pre-configuration Tasks

Before configuring association between a BFD session and an interface, create a BFD session.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this function.

A BFD session is configured to report faults to an interface.

By default, a BFD session is not enabled to report faults to an interface.

When a BFD session detects a fault, the physical status of the interface bound to the BFD session becomes Down.

The physical interface associated with BFD cannot be the interface of the BFD link. Otherwise, a link deadlock occurs.
