Deployment Guide

Example
DellEMC(conf)#bfd save-downsession
bfd sched-tune-max
Fine-tune BFD operation to prevent the BFD flaps (if occurs) when configuring the BFD timer at transmit and receive intervals
as 100 with a multiplier of 3.
Syntax
bfd sched-tune-max
To disable the configuration, use no bfd sched-tune-max command.
NOTE: Use this command only when there are BFD flaps.

Command
History
This guide is platform-specific. For command information about other platforms, see the relevant Dell
EMC Networking OS Command Line Reference Guide.
Version Description
9.14(1.3) Introduced on the S3048–ON, S4048–ON, S4048T-ON, S6010–ON, and Z9100–
ON.
Usage
Information
Although the Dell EMC Networking OS help does not display the sched-tune-max keyword under bfd
configuration, the command works if you manually type it in the CLI prompt.
No need to enable bfd sched-tune-max command, if the BFD timer is configured at transmit and
receive intervals more than 100 with a multiplier of 3.
Dell EMC Networking OS saves the BFD tunable configuration in the running configuration and this
configuration sustains the OS9 reload.
Example
DellEMC(conf)#bfd sched-tune-max
ip route bfd
Enable BFD for all neighbors configured through static routes.
Syntax
ip route bfd [vrf vrf-name] [prefix-list prefix-list-name] [interval
interval min_rx min_rx multiplier value role {active | passive}]
To disable BFD for all neighbors configured through static routes, use the no ip route bfd [vrf
vrf-name] [prefix-list prefix-list-name] [interval interval min_rx min_rx
multiplier value role {active | passive}] command.
Parameters
vrf vrf-name Enter the keyword vrf and then the name of the VRF.
prefix-list prefix-
list-name
(Optional) Enter the keyword prefix-list followed by the name of the prefix
list to enable or disable BFD on specific neighbors.
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
receives control packets from the remote system. The range is from 50 to 1000.
The default is 200.
