Configuration Guide - Reliability
Context
Debugging affects system performance. After debugging is complete, run undo debugging
all command to disable debugging immediately.
If a BFD fault occurs, run the following debugging command in the user view to locate the fault.
For the procedure of displaying the debugging information, refer to the chapter "Maintenance
and Debugging" in the Quidway S3700 Series Ethernet Switches Configuration Guide - System
Management.
Procedure
Step 1 Run the debugging bfd { all | defect-detect | error | event | fsm | ha | packet | process | product-
interface | session-management | timer } command in the user view to enable the debugging
of the BFD module.

6.9 Configuration Examples

This section provides several configuration examples of BFD.
6.9.1 Example for Configuring Single-Hop BFD on a Layer 2
Interface
Networking Requirements
Interfaces of the S3700 are Layer 2 interfaces. If you need to detect the connectivity of the Layer
2 forwarding link between two directly connected S3700s, configure single-hop BFD, and bind
the BFD session to a multicast IP address and local interface.
As shown in
between Switch A and Switch B.
