Configuring BFD Configuring BFD
page 20-12 OmniSwitch AOS Release 7 Network Configuration Guide June 2013
Note. Once the default state of the BFD session is changed and the session is enabled, parameter values
are no longer configurable. To subsequently change parameter values, disable the BFD session. See
“Enabling or Disabling BFD Status” on page 20-14 for more information.
Configuring a BFD Session
To configure a BFD session, use the ip bfd interface command and specify an existing IP interface name.
For example:
-> ip bfd interface bfd-vlan-101
The above command configures BFD with the name bfd-vlan-101. See “Enabling or Disabling BFD
Status” on page 20-14 for more information.
To delete the BFD session, use the no form of the above command. For example:
-> no ip bfd interface bfd-vlan-101
The above command deletes the BFD session on bfd-vlan-101.
Note. The BFD interface session must be associated to an existing IP interface that is configured with an
IP address.
Configuring the BFD Transmit Time interval
Transit Time Interval is the minimum amount of time that BFD waits between each successive
transmission of control packets. BFD allows you to change the default value and set the transmit time
interval from the valid range.
To change the global transmit time interval for BFD control packets, use the ip bfd transmit command.
For example:
-> ip bfd transmit 500
The above command changes the global transmit time interval to 500 msecs.
To change the transmit time interval for a specific BFD interface session, use the ip bfd interface trans-
mit command along with the name and transmit time interval in milliseconds. For example:
-> ip bfd interface bfd-vlan-101 transmit 500
The above command changes the transmit time interval value to 500 msecs on bfd-vlan-101.
The global transmit time interval serves as the default interval value for transmitting BFD control packets.
This default value is overridden when a specific transmit value is configured.
Configuring the BFD Receive Time Interval
Receive Time Interval is the minimum amount of time that BFD waits to receive control packets before
determining if there is a problem. BFD allows you to change the default value and set the receive time
interval from the valid range.
To change the global receive time interval for BFD control packets, use the ip bfd receive command. For
