Configure BFD for an IPv4 Interface on a Port
About this task
BFD provides a failure-detection mechanism between two systems. Use the following procedure to enable and configure BFD for an IPv4 interface on a port.
Procedure
- In the navigation pane, expand .
 - Select IP.
 - Select the BFD tab.
 - Select Enable.
 - Optional: In the MinRxInterval field, specify the minimum receive interval..
 - Optional: In the TxInterval field, specify the transmit interval.
 - Optional: In the Multiplier field, 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.  |
