show ipv6 bfd neighbors
show ipv6 bfd neighbors next-hop WORD<0-128>
show ipv6 bfd neighbors vrf
show ipv6 bfd neighbors vrfids
Specifies the next-hop IPv6 address in the format a:b:c:d:e:f:g:h.
Specifies a VRF instance by VRF name.
Specifies a VRF or range of VRFs by ID.
User EXEC
BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine Feature Support Matrix.
The show ipv6 bfd neighbors command displays the following information:
Output Field |
Description |
---|---|
MY_DISC |
Specifies the local discriminator for the BFD session. |
YOUR_DISC |
Specifies the remote discriminator for the BFD session. |
NEXT_HOP |
Specifies the next-hop IPv6 address. |
STATE |
Specifies the BFD session state. Possible values are Down, Up, Init, and AdminDown. |
MULTI |
Specifies the multiplier used to calculate the amount of time BFD waits before declaring a receive timeout. |
MIN_TX |
Specifies, in microseconds, the minimum interval that the local system prefers to use when transmitting BFD control packets. |
MIN_RX |
Specifies, in microseconds, the minimum interval between received BFD control packets. |
ACT_TX |
Specifies, in microseconds, the actual transmission interval. |
DETECT_TIME |
Specifies the period of time without receiving BFD packets, after which the session is determined to have failed. |
REMOTE_STATE |
Specifies the BFD session state of the remote system. |
APP |
Specifies the application configured on the BFD session. |
RUN |
Specifies the application running on the BFD session. |
