configure bfd vlan

configure bfd vlan vlan_name [{detection-multiplier multiplier} {receive-interval rx_interval} {transmit-interval tx_interval}]

Description

Configures BFD transmit (TX) and receive (RX) intervals and multipliers on the VLAN.

Syntax Description

vlan_name

Specifies the VLAN.

multiplier

Specifies the detection multiplier. The range is 1 to 255.

rx_interval

Specifies the receive interval for control packets in milliseconds. The range is 100 to 4294967 ms. (3 to 4294967 ms if hardware assist is enabled).

tx_interval

Specifies the transmit interval for control packets in milliseconds. The range is 100 to 4294967 ms. (3 to 4294967 ms if hardware assist is enabled).

Default

The default value for RX and TX intervals is 1000 ms.

The default value for the detection-multiplier is 3.

Usage Guidelines

Use this command to configure BFD.

Use the show bfd vlan command to display the current settings.

Example

The following command configures a transmit and receive interval of 2000 ms and a detection multiplier of 2 on the VLAN vlan1:

# configure bfd vlan vlan1 detection-multiplier 2 receive-interval 2000 transmit-interval 2000

Receive interval of 0

An rx_interval value of 0 means that this system does not want to receive any periodic BFD Control packets. A system may transmit a value of 0 for the Required MinRX Interval to indicate that the remote system should send no packets.

# configure bfd vlan vlan1 detection-multiplier 2 receive-interval 0 transmit-interval 2000
