Networking: NE40E—transmission network—NE40E
To enable the NE40Es to detect the interface status change of each other, a client configures BFD on the two NE40Es. However, BFD does not take effect after the configuration is complete.
The on-site Huawei technical support personnel check the BFD configuration and find that the commit command is not run and the BFD session is not associated with the interface. That is why BFD fails to take effect and cannot detect an interface Down event.
BFD is not configured following the configuration rules.
Configure BFD according to the configuration rules.
