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 

example:
