The above command enables the administrative status of the BFD interface named bfd-vlan-101.
Note that a BFD interface must be disabled before any of its parameters can be changed. To disable a BFD
interface, use the ip bfd-std interface status
interface, use the ip bfd-std interface status
command with the disable keyword. For example:
-> ip bfd-std interface bfd-vlan-101 status disable
To verify the BFD status and configuration for the switch, use the
ple:
-> show ip bfd-std
Version : 1,
Admin Status
: Enabled,
Transmit interval : 200,
Receive interval : 200,
Multiplier : 3,
Echo status : Enabled,
Echo interval : 200,
Mode : Asynchronous,
Protocols registered : OSPF,
The above command shows that BFD is registered with the OSPF protocol and has a transmit interval of
200 msecs, receive interval of 200 msecs, multiplier 3, echo interval of 200 msecs, and operational mode
set as asynchronous mode.
200 msecs, receive interval of 200 msecs, multiplier 3, echo interval of 200 msecs, and operational mode
set as asynchronous mode.
To verify the BFD status and configuration for a specific interface, use the
command. For example:
->show ip bfd-std interface

The output above displays the interfaces participating in the BFD sessions, along with their IP interface
names and respective BFD session parameters. To see additional detail for a specific interface, use the
show ip bfd-std interface command and specify an interface name. For example:
