Parameters

Parameter Name	Parameter Meaning
Index	Indicates the index of the BFD session.
ConfigurationName	Indicates the configuration name of the BFD session.
PeerIp	Indicates the bound destination IP address.
BindIfIndex	Indicates the index of the bound interface.
BindIfName	Indicates the name of the bound interface.
Diagnosis	Indicates information about session diagnostic characters. 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	Indicates the index of the bound VPN instance.
BindVpnName	Indicates the name of the bound VPN instance.
SessionType	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.
DefaultIp	Indicates the default multicast IP address.
BindType	2 or 3: Peer IP address (multi-hop IP link detection). 1 or 4: Interface (single-hop IP link detection). 5: FEC (detection of a specified FEC link). 6: TUNNELIF (detection of a specified tunnel interface link). 7: OSPF (OSPF neighbor link detection). 8: ISIS (ISIS neighbor link detection). 9: LDP_LSP (LDP LSP detection). 10: STATIC_LSP (static 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). 14: LSP_PASSIVE (reversed LSP link detection). 15: VSI_PW (VSI PW link detection). 16: LDP_TUNNEL (LDP tunnel detection). 17: VXLAN (VXLAN link detection).
StaticLspName	Indicates the name of the static LSP. This parameter is always displayed as "-".
PwSecondary	Secondary PW flag. 1: primary PW. 2: secondary PW. 3: non-PW link.
NextHop	Indicates the IP address of the next hop.
VcId	Indicates the ID of the VC.
VsiName	Indicates the name of the VSI.
VsiPeerAddress	Indicates the destination address of the VSI.
DiscrAuto	Indicates the static auto-negotiation identifier.
PeerIpv6	Indicates the bound destination IPv6 address.
Ipv6NextHop	Indicates the next-hop IPv6 address.

Possible Causes

Cause 1: A BFD session was created. That is, the BFD session changed from Init to Up. Cause 2: The undo shutdown command was run to restore the BFD session. That is, the BFD session changed from AdmDown to Up.

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

Procedure

The log message is informative only, and no action is required.
