CAUTION
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

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
, a BFD session is created to detect the connectivity of the Layer 2 link
between Switch A and Switch B.
