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|ipv6 bfd interface
transmit command along with the name and transmit time interval in milliseconds. For example:
-> ip bfd interface bfd-vlan-101 transmit 500
-> ipv6 bfd interface bfd-vlan-201 transmit 500
The above command changes the transmit time interval value to 500 msecs on “bfd-vlan-101” and “bfd-
vlan-201”.
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:
-> ip bfd receive 500
The above command configures the global receive time interval of 500 msecs.
To change the receive time interval for BFD control packets, use the ip|ipv6 bfd interface receive
command. For example:
-> ip bfd interface bfd-vlan-101 receive 500
-> ipv6 bfd interface bfd-vlan-201 receive 500
The above command changes the receive time interval value to 500 msecs on “bfd-vlan-101” and “bfd-
vlan-201”.
The global receive time interval serves as the default interval value for receiving BFD control packets.
The default interval value is overridden when a specific receive value is configured.
Configuring the BFD Echo interval
The time interval between received BFD echo packets is configurable and applies when the echo function
is enabled. When this function is active, a stream of Echo packets is sent to a peer, which then loops these
Note. The BFD interface session must be associated to an existing IPv4 or IPv6 interface that is configured
with an IPv4 or IPv6 address.
