Procedure
- In the navigation pane, expand .
- Select IP.
- Select the BFD tab.

- Optional: In MinRxInterval, specify the minimum receive interval.
- Optional: In TxInterval, specify the transmit interval.
- Optional: In Multiplier, specify a value for the multiplier used to calculate a receive timeout.
BFD Field Descriptions
Use the data in the following table to use the BFD tab.
| Name | Description |
|---|---|
|
Enable |
Enable BFD on the port. |
|
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:
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:
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. |
