Home / Core Solution for Loop Issues in Huawei Switches

This guide will help you detect and fix network loops using Spanning Tree Protocol (STP), switch configuration adjustments, and loop prevention techniques. What Causes a Network Loop? A network loop can occur due to: ✅ Redundant Cable Connections – Multiple physical links between. This document discusses how to configure an Eth-Trunk in manual load balancing mode, how to configure an Eth-Trunk in LACP mode, and how to locate an Eth-Trunk fault. The S2700 V100R006C00 is a high-performance Ethernet switch that provides a range of features to meet the needs of modern networks. Loopback detection (LBDT) technology enables a device to periodically send detection packets to detect whether there are loops on the downstream network connected to the device.
