<adaptive-reception-interval>—Adjusted value of minimum reception interval.
<authentication>—Authentication status.
<bfd-client>—Information about the clients.
<detection-multiplier>—Desired detect time multiplier for BFD control packets.It is multiplied by the negotiated control packet receptioninterval to determine the session detection time (time todetect whether the session is alive).
<echo-mode-desired>—Indicates whether the local system proposes that echotransmissions be enabled for the BFD session.
<echo-mode-state>—Indicates whether echo transmissions are enabled for theBFD session.
<holddown-timer>—Status of version negotiation.
<issu-state>—ISSU state of the session.
<local-diagnostic>—Information provided by the local host about BFD sessionsthat have failed (for example if the node is administrativelydown or a control timer has expired).
<local-discriminator>—Authentication code used by the local system to identify theBFD session.
<logical-system-id>—Logical system on which the session is established.
<minimum-asynchronous-interval>—Minimum amount of time that the local system proposes forthe delay between transmission of asynchronous control packetsacross the BFD session (seconds).
<minimum-reception-interval>—Minimum amount of time that the local system waits betweenchecks for newly received control packets (seconds).
<minimum-slow-interval>—Either one second or the minimum asynchronous interval,whichever is greater.
<minimum-transmission-interval>—Minimum amount of time that the local system proposes forthe delay between transmission of control packets across theBFD session (seconds). It is either the minimum slow interval orthe adaptive asynchronous transmission interval.

<neighbor-minimum-reception-interval>—Minimum amount of time that the remote system waits betweenchecks for newly received control packets (seconds).
<neighbor-minimum-transmission-interval>—Minimum amount of time that the remote system proposes forthe delay between transmission of control packets across the BFDsession (seconds).
<neighbor-session-multiplier>—Neighbor's detection multiplier.
<no-absorb>—Incoming packets are not absorbed.
