Output Fields
Table 1 describes the output fields for the show bfd subscriber session command. Output fields are listed in the approximate order in which they appear.
Field Name |
Field Description |
Level of Output |
|---|---|---|
Address |
IP Address on which the BFD subscriber session is active. |
All levels |
State |
State of the BFD subscriber session: |
All levels |
Interface |
Interface on which the BFD subscriber session is active. |
All levels |
Detect Time |
Negotiated time interval, in seconds, used to detect BFD control packets. |
All levels |
Transmit Interval |
Time interval, in seconds, used by the transmitting system to send BFD control packets. |
All levels |
Multiplier |
Negotiated multiplier by which the time interval is multiplied to determine the detection time for the transmitting system. |
All levels |
TX interval |
Time interval, in seconds, used by the host system to transmit BFD control packets. |
|
RX interval |
Time interval, in seconds, used by the host system to receive BFD control packets. |
|
Local diagnostic |
Local diagnostic information about failing BFD subscriber sessions. |
|
Remote diagnostic |
Remote diagnostic information about failing BFD subscriber sessions. |
|
Remote state |
Indication that the remote system's BFD packets have been received and whether the remote system is receiving transmitted control packets. |
|
Version |
BFD version: |
|
routing table index |
Value of the routing table index. A value of 0 (zero) denotes a route in the default routing table managed by enhanced subscriber management. |
|
Min async interval |
Minimum amount of time, in seconds, between asynchronous control packet transmissions across the BFD subscriber session. |
|
min slow interval |
Minimum amount of time, in seconds, between synchronous control packet transmissions across the BFD subscriber session. |
|
Adaptive async TX interval |
Transmission interval being used because of adaptation. |
|
RX interval |
Receive interval being used because of adaptation. |
extensive |
Local min TX interval |
Minimum amount of time, in seconds, between control packet transmissions on the local system. |
|
minimum RX interval |
Minimum amount of time, in seconds, between control packet detections on the local system. |
|
Remote min TX interval |
Minimum amount of time, in seconds, between control packet transmissions on the remote system. |
|
min RX interval |
Minimum amount of time, in seconds, between control packet detections on the remote system. |
|
Local discriminator |
Authentication code used by the local system to identify that BFD subscriber session. |
|
Remote discriminator |
Authentication code used by the remote system to identify that BFD subscriber session. |
