Version 8.3.12.0 Introduced on S4810
bfd all-neighbors Enable BFD sessions with all neighbors discovered by Layer 3
protocols IS-IS, OSPF or BFP on router interfaces.
neighbor bfd disable Explicitly disable a BFD session with a BFP neighbor or a BFP peer
group.
show bfd neighbors Display BFD neighbor information on all interfaces or a specified
interface.
disable
(OPTIONAL) Enter the keyword disable to disable BFD on this
interface.
interval milliseconds
(OPTIONAL) Enter this keyword to specify non-default BFD
session parameters beginning with the transmission interval.
Range: 50 to 1000

min_rx milliseconds
Enter this keyword to specify the minimum rate at which the local
system would like to receive control packets from the remote system.
Range: 50 to 100
Default: 100
multiplier value
Enter this keyword to specify the number of packets that must be
missed in order to declare a session down.
Range: 3 to 50
Default: 3
role [active | passive] Enter the role that the local system assumes:
• Active—The active system initiates the BFD session. Both
systems can be active for the same session.
• Passive—The passive system does not initiate a session. It only
responds to a request for session initialization from the active
system.
Default: Active
