Parameters

Parameter Name	Parameter Meaning
Index	BFD session ID
ConfigurationName	BFD session name
BindIfIndex	Bound interface index
BindIfName	Bound interface name
Diagnosis	Session diagnostic word 0: No diagnostic word 1: Detection time Down 2: Echo detection Down 3: Neighbor advertisement Down 4: Forwarding plane reset 5: Path Down 6: Cascading path Down 7: Administratively Down 8: Reverse cascading path Down 9: Peer administratively Down 25: IP error code stop 26: IP error code start 27: Section error code stop 28: Section error code start 29: LSP error code stop 30: LSP ingress error code start 31: LSP transit error code start
BindVrfIndex	Index of the bound VPN instance
BindVpnName	Name of the bound VPN instance
SessionType	Indicates the type of a session. 1: static, which indicates that the BFD session is statically configured. 2: Dynamic, which indicates that the BFD session is dynamically triggered. 3: Entire_Dynamic: indicates that a BFD session is dynamically triggered. After the function of passively creating a BFD session is enabled on the egress of the LSP, the BFD session is created. 4: Static_Auto: indicates a static BFD session with automatically negotiated discriminators.
BindType	Bound type: 2 or 3: Peer IP address (multi-hop IP link detection). 1 or 4: Interface (single-hop IP link detection). 9: LDP_LSP (LDP LSP detection). 11: TE_LSP (detection of the LSP bound to a TE tunnel). 12: TE_TUNNEL (TE tunnel detection). 13: PW (PW link detection). 15: VSI_PW (VSI PW link detection).
StaticLspName	Static LSP name The value is constantly -.
PwSecondary	Secondary PW flag. 1: primary PW. 2: secondary PW. 3: non-PW link.
VcId	VC ID
VsiName	VSI name
VsiPeerAddress	VSI destination address
DiscrAuto	Static auto-negotiation discriminator
PeerIpv6	Bound destination IPv6 address
Ipv6NextHop	Next hop IPv6 address

Possible Causes

Cause 1: The BFD session was successfully created, and the session state changed from Init to Up.

Cause 2: The BFD session was restored using the undo shutdown command, and the session state changed from AdmDown to Up.

Cause 3: The BFD session state changed from Down to Up.
