BFD-STD-MIB

Use the Bidirectional Forwarding Detection (BFD) MIB to monitor and receive failure alerts for the bidirectional path between two forwarding engines, such as interfaces, data links, or the actual engines. For example, you can check the bfdSessState object to see the state of a BFD session between forwarding engines. In the Palo Alto Networks implementation, one of the forwarding engines is a firewall interface and the other is an adjacent configured BFD peer.
RFC 7331 defines this MIB.
