Name Description

Enable

Enable BFD on the CLIP interface.

MinRxInterval

Specifies the minimum interval, in milliseconds, between received BFD control packets that the local system is capable of supporting. The default is 200 ms.

Note: For XA1400 Series, the default is 1000 ms.
Note:

The minimum value you can configure for the receive interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the receive interval. You can configure any remaining BFD sessions with a receive interval that is greater than or equal to the 200 ms default value.

TxInterval

Specifies the transmit interval in milliseconds. The default is 200 ms.

Note: For XA1400 Series, the default is 1000 ms.
Note:

The minimum value you can configure for the transmit interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the transmit interval. You can configure any remaining BFD sessions with a transmit interval that is greater than or equal to the 200 ms default value.

Multiplier

Specifies a value for the multiplier used to calculate a receive timeout. The default is 3.

Note:

If you configure the transmit interval or the receive interval as 100 ms, you must configure a value of 4 or greater for the multiplier.
