Configuring BFD Configuring BFD
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 20-17
The above command disables BFD globally on the routing instance. Note that disabling BFD does not
remove the existing BFD configuration from the routing instance. Also, when BFD is globally disabled,
all BFD functionality is disabled for the routing instance, but configuring BFD is still allowed.
To enable a BFD session, use the ip|ipv6 bfd interface admin-state command. For example:
-> ip bfd interface bfd-vlan-101 admin-state enable
-> ipv6 bfd interface bfd-vlan-201 admin-state enable
The above command enables the administrative status of “bfd-vlan-101” and “bfd-vlan-201”.
Note that a BFD session must be disabled before any of its parameters can be changed. To disable a BFD
session, use the ip bfd interface admin-state
command or the ipv6 bfd interface admin-state command
with the disable keyword. For example:
-> ip bfd interface bfd-vlan-101 admin-state disable
-> ipv6 bfd interface bfd-vlan-201 admin-state disable
To verify the global BFD status and configuration for the switch, use the show ip bfd command,. For
example:
-> show ip bfd
BFD Version Number = 1,
Admin Status = Enabled,
Desired Transmit Interval = 300,
Minimum Receive Interval = 300,
Detection Time Multiplier = 3,
Minimum Echo Receive Interval = 300,
Applications Registered = STATIC-ROUTING OSPF
The above command shows that BFD is registered with the OSPF protocol and has a transmit interval of
300 msecs, receive interval of 300 msecs, multiplier 3, and echo interval of 300 msecs.
To verify the BFD status and configuration, use the show ip|ipv6 bfd interfaces command. For example:
-> show ip bfd interfaces
Interface Admin Tx Min Rx Min EchoRx Detect Oper
Name Status Interval Interval Interval Mult Status
---------------------+----------+----------+----------+----------+------+------
bfd-intf1 enabled 300 300 300 3 UP
bfd-intf2 enabled 300 300 300 3 UP
-> show ipv6 bfd interfaces
Interface Admin Tx Min Rx Min EchoRx Detect Oper
Name Status Interval Interval Interval Mult Status
---------------------+----------+----------+----------+----------+------+------
bfd-intf3 disabled 300 300 300 3 DOWN
The output above displays the interfaces participating in the BFD sessions, along with their IPv4 or IPv6
interface names and respective BFD session parameters. To see additional detail for a specific interface,
use the show ip|ipv6 bfd interfaces command and specify an interface name. For example:
-> show ip bfd interfaces bfd-intf1
Interface Name = bfd-intf1,
Interface IP Address = 100.1.1.1,
Admin Status = Enabled,
Desired Transmit Interval = 300,
Minimum Receive Interval = 300,
