5. Configure BFD parameters (you can use default BFD parameters instead).
# Configure Switch A.
[SwitchA] bfd session init-mode active
[SwitchA] interface vlan-interface 100
• Configure the minimum interval for transmitting BFD control packets as 500 milliseconds.
[SwitchA-Vlan-interface100] bfd min-transmit-interval 500
• Configure the minimum interval for receiving BFD control packets as 500 milliseconds.
[SwitchA-Vlan-interface100] bfd min-receive-interval 500
• Configure the detect multiplier as 7.
[SwitchA-Vlan-interface100] bfd detect-multiplier 7
[SwitchA-Vlan-interface100] quit
# Configure Switch C.
[SwitchC] bfd session init-mode active
[SwitchC] interface vlan-interface 101
• Configure the minimum interval for transmitting BFD control packets as 500 milliseconds.
[SwitchC-Vlan-interface101] bfd min-transmit-interval 500
• Configure the minimum interval for receiving BFD control packets as 500 milliseconds.
[SwitchC-Vlan-interface101] bfd min-receive-interval 500
• Configure the detect multiplier as 7.
[SwitchC-Vlan-interface101] bfd detect-multiplier 7
[SwitchC-Vlan-interface101] return
6. Verify the configuration.
The following operations are made on Switch C. Operations on Switch A and Switch B are similar and
are not shown.
# Display detailed BFD session information.

The output shows that a BFD session is established between Switch A’s VLAN-interface 100 and Switch
C’s VLAN-interface 101 and that BFD runs properly.
