61.4 ULPP Troubleshooting
At present, configuration of more than 2 multi-uplinks is allowed, but it may cause loopback, so is
not recommended.
With the normal configuration, if the broadcast storm happen or the communication along the ring is
broken, please enable the debug of ULPP, copy the debug information of 3 minutes and the
configuration information, send them to our technical service center.
