Command
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2
interface int-if
Example:
switch(config)# interface ethernet 2/1

Step 3
bfd interval mintx min_rx msec
multiplier value
Example:
switch(config-if)# bfd interval 50
min_rx 50 multiplier 3
Step 4
bfd authentication keyed-sha1 keyid id
key ascii_key
Example:

keyed-sha1 keyid 1 ascii_key cisco123
Step 5

Purpose
Enters configuration mode.
Enters interface configuration mode. Use the ?
keyword to display the supported interfaces.
Configures the BFD session parameters for all BFD
sessions on the interface. This overrides the global
BFD session parameters. The mintx and msec range is
from 50 to 999 milliseconds and the default is 50. The
multiplier range is from 1 to 50. The multiplier default
is 3.
(Optional) Configures SHA-1 authentication for all
BFD sessions on the interface. The ascii_key string is
a secret key shared among BFD peers. The id value, a
number between 0 and 255, is assigned to this
particular ascii_key. BFD packets specify the key by
id, allowing the use of multiple active keys.
To disable SHA-1 authentication on the interface, use
the no form of the command.
(Optional) Displays the BFD running configuration.
(Optional) Saves this configuration change.
