Table 1-94 explains the output fields.
Table 1-94: Show BFD session fields
Entry | Description |
|---|
Session Interface Index | ID number of the Interface. |
Session Index | ID number for this BFD session. |
Lower Layer | The lower layer protocol on which BFD is carried (IPv4 or IPv6). |
Session State | The state of the session: Init: session is initializing Up: session is up. Down: session is down AdminDown: session has been administratively shutdown indefinitely |
Local Discriminator | A unique value generated by the transmitting device used to demultiplex multiple BFD sessions between the same pair of devices. |
Remote Discriminator | The discriminator received from the corresponding remote device. This field is zero if the value is unknown. |
Local Address | Local address of the transmitting device. |
Remote Address | Remote address of the receiving device. |
Local Port | UDP port number of the transmitting device. |
Remote Port | UDP port number of the receiving device. |
Min Tx | Minimum transmit interval in milliseconds. |
Min Rx | Minimum receive interval in milliseconds. |
Multiplier | The negotiated transmit interval, multiplied by this value, provides the detection time for the receiving system in asynchronous mode. |
UP Count | The number of times the BFD session has been in up state. |
UPTIME | The length of time this BFD session has been in the up state. |
