Session Type Sess-Type | Single Hop Multihop Arbit Path Multihop OOB Signalled Multihop Unidirectional. |
Session State Sess-State | The State of the session: Init: The session is initializing Up: The session is up. Down: The session is down AdminDown: The session has been administratively shutdown indefinitely. |
Local Discriminator | A unique discriminator value generated by the transmitting device used to demultiplex multiple BFD sessions between the same pair of devices. |
Local Address | Local address of the transmitting device. |
Remote Discriminator Remote-Disc | The discriminator received from the corresponding remote device; zero if that value is unknown. |
Remote Address Remote-Addr | Remote address of the receiving device. |
Local Port | UDP port number of the transmitting device. |
Remote Port | UDP port number of destination. |

Min Tx | Minimum transmit interval. |
Min Rx | Minimum receive interval. |
Multiplier | The negotiated transmit interval, multiplied by this value, provides the detection time for the receiving system in asynchronous mode. |

Sess down time | Length of time this BFD session has been down. |
Bfd GTSM | Whether the BFD session has enabled or disabled the Generalized TTL Security Mechanism (GTSM), which uses the time to live (TTL) or hop count to prevent off-link attackers from spoofing packets. |
Bfd Authentication Enabled | When authentication is enabled. |

IPv6 Pkt Out | Number of IPv6 packets that have been transmitted during this BFD session. |
UP Count | Number of times the BFD session has been up. |
UPTIME | Length of time this BFD session has been up. |
BGP-> Client ID | Protocol and module ID number of this BFD session’s neighboring device. |
Flags | Session state of the neighboring device. |
Interface | The interface on which the VRF resides. |
Down-Reason | The reason causing the VRF to be down. |
