Configuring BFD Configuring BFD
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 30-17
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
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 show ip bfd-std command,. For exam-
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.
To verify the BFD status and configuration for a specific interface, use the show ip bfd-std interfaces
command. For example:
->show ip bfd-std interface
Interface Admin Tx Min Rx Oper
Name Mode Status Interval Interval Multiplier Status
-----------+------------+---------+---------+---------+-----------+----------
vlan-10 ASYNCHRONOUS enabled 100 100 3 UP
vlan-20 ASYNCHRONOUS disabled 0 0 5 DOWN
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:
-> show ip bfd-std interface vlan-10
Interface IP Address: = 215.20.10.1,
Admin Status: = Enabled,
Mode: = ASYNCHRONOUS,
Echo Status: = Disabled,
Transmit Interval: = 100,
Receive Interval: = 100,
Multiplier: = 3,
Echo Interval: = 100,
L2 Hold Down Interval = 100
