display isis bfd interface
Function
The display isis bfd interface command displays information about BFD-enabled IS-IS interfaces.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Parameters
| Parameter | Description | Value |
|---|---|---|
| process-id | Specifies an IS-IS process ID. | The value is an integer that ranges from 1 to 65535. |
Usage Guidelines
BFD can provide millisecond-level fault detection. It can work with IS-IS to fast detect faults on neighboring devices and instruct IS-IS to recalculate routes for correct packet forwarding. You can run the display isis bfd interface command to check information about BFD-enabled IS-IS interfaces.
Example
# Display information about BFD-enabled IS-IS interfaces.

Description |
|---|---|
Interface |
BFD-enabled IS-IS interface. To enable BFD on an IS-IS interface, run the bfd all-interfaces enable or isis bfd enable command. |
BFD.State |
BFD status on the IS-IS interface:
|
Min-Tx |
Minimum interval for transmitting BFD packets. To set the minimum interval, run the bfd all-interfaces or isis bfd command. |
Min-Rx |
Minimum interval for receiving BFD packets. To set the minimum interval, run the bfd all-interfaces or isis bfd command. |
Mul |
Local detection multiplier. To set the local detection multiplier, run the bfd all-interfaces or isis bfd command. |
