column Enumeration

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.
