Feature Limitations

If a loop occurs on the path detected by BFD, the change of the network topology where the loop exists may cause the BFD session to flap at one time.

When BFD is bound to a sub-interface, only dot1q terminal sub-interface supports BFD function.

When the BFD session is bound to the Eth-Trunk and the detection time is less than 300 ms, you are not advised to add or delete Eth-Trunk member interfaces. Otherwise, the BFD session may flap.

To implement 50-ms switching, the device must support the 3.3-ms interval for sending and receiving BFD packets. The configuration is supported in the following situations:
  • The MPU is equipped with the LE0MFSUA subcard or the MPU is LH2D2SRUDC00 or LE2D2SRUDC01.
  • For the S9306 and S9312, you need to first run the assign system-resource-mode static command to configure the switch to statically allocate module resources.
