Description: This variable defines current operating mode that BFD session is running in.
The primary mode which the BFD session runs in is known as Asynchronous mode. In this mode, the systems periodically send BFD Control packets to one another, and if a number of those packets in a row are not received by the other system, the session is declared to be down.
The second mode is known as Demand mode. In this mode, it is assumed that each system has an independent way of verifying that it has connectivity to the other system. Once a BFD session is established, the systems stop sending BFD Control packets, except when either system feels the need to verify connectivity explicitly, in which case a short sequence of BFD Control packets is sent, and then the protocol quiesces.
An adjunct to both modes is the Echo function. When the Echo function is active, a stream of BFD Echo packets is transmitted in such a way as to have the other system loop them back through its forwarding path. If a number of packets of the echoed data stream are not received, the session is declared to be down. The Echo function may be used with either Asynchronous or Demand modes.
The 'asynchModeWOEchoFun' indicates this BFD session operates in the Asynchronous mode, and doesn't support the Echo Function.
The 'demandModeWOEchoFunction' indicates this BFD session operates in the Demand mode, and doesn't support the Echo Function.
The 'asyncModeWEchoFun' indicates this BFD session operates in the Asynchronous mode, and also supports the Echo Function.
The 'demandModeWEchoFunction' indicates this BFD session operates in the Demand mode, and also supports the Echo Function.
What is hpnicfBfdSessOperMode?
Shows which of the four BFD operating modes this session actually negotiated: Asynchronous or Demand mode, each with or without the Echo function. Asynchronous mode without Echo is the common default; seeing Demand mode tells an admin the session relies on the local system's own connectivity checks instead of continuous BFD control packets.
