Dell Command Line Reference Guide for the S4048–ON System 9.14.2.4

To remove all BFD sessions with IS-IS neighbors discovered on this interface, use the no isis bfd all-neighbors [disable | [interval interval min_rx min_rx multiplier value role {active | passive}]] command.

disable

(OPTIONAL) Enter the keyword disable to disable BFD on this interface.

interval milliseconds

(OPTIONAL) Enter the keywords interval to specify non-default BFD session parameters beginning with the transmission interval. The range is from 50 to 1000. The default is 200.

min_rx milliseconds

Enter the keywords min_rx to specify the minimum rate at which the local system would like to receive control packets from the remote system. The range is from 50 to 1000. The default is 200.

multiplier value

Enter the keywords multiplier to specify the number of packets that must be missed in order to declare a session down. The range is from 3 to 50. The default is 3.

role [active | passive]

Enter the role that the local system assumes:

• Active — active system initiates the BFD session. Both systems can be active for the same session.
• Passive — passive system does not initiate a session. It only responds to a request for session initialization from the active system.

The default is Active.

This command provides the flexibility to fine-tune the timer values based on individual interface needs when ISIS BFD is configured in CONFIGURATION mode. Any timer values specified with this command overrides timers set using the bfd all-neighbors command. Using the no form of this command does not disable BFD if BFD is configured in CONFIGURATION mode.

To disable BFD on a specific interface while BFD is configured in CONFIGURATION mode, use the keyword disable.
