This article will introduce in detail the nine query commands of Huawei switches to help you quickly understand the operating status and configuration
Execute the command “combo enable fiber” in interface mode to switch to the optical interface; on the contrary, “undo combo enable fiber” switches to the default
Switch stacking is a cornerstone of modern network design, enabling simplified management, improved redundancy, and scalable bandwidth. Huawei''s stacking technology (e.g.,
Enabling and Disabling Stacking On the S5700-EI or S5700-SI, run the stack enable or undo stack enable command in the system view to enable or disable stacking. Enabling or disabling stacking
This text is a guide detailing Basic Command Line Interface (CLI) Commands on Huawei brand switches. It provides step-by-step instructions for users to perform
If your network feels sluggish or devices mysteriously disconnect, the culprit might be smaller than you think—buried inside your Huawei switch. SFP power levels (optical transmit and receive power) are
Generally fiber optic connections use either plain fiber-Ethernet or more commonly GPON (which still carries Ethernet data), and Ethernet-to
A trunk interface often connects to a switch, router, AP, or voice terminal that can receive and send tagged and untagged frames simultaneously.
Troubleshooting Interface Down Problems This document describes how to troubleshoot the fault that an interface is down. An interface may go down in many situations. To check the interface status, run
Interface range configuration is a feature on Huawei switches (and other managed switches) that allows you to apply configuration commands to multiple interfaces (ports) simultaneously, instead of
40GE optical interfaces support unidirectional single-fiber communication only when no optical module is installed or 40GE optical modules are installed. When enabling unidirectional single-fiber
HUAWEI S Series Switch-Configure Login Through the Web System video demonstrates how to log in to a switch through the web system.

This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
This document explains Ethernet interface configuration commands, including functions, syntax, parameters, views, default level, guidelines, examples, and related
This page provides configuration commands for Ethernet interfaces on Huawei devices, covering settings like duplex mode and auto-negotiation.
Step 1: Connect the COM port on the PC and the console port on the switch by a cable. Step 2: Power on all devices to perform a self-check. Step 3:
Example for Switching an Interface to Layer 3 Mode Networking Requirements As shown in Figure 3-15, PC1, PC2, PC3, and PC4 are on four network segments, and SwitchB, SwitchC,
Please contact your Web Application administrator if this problem persists.
Check the status and configuration parameters of the interfaces on the two ends. Ensure that the interfaces run properly and have the same configuration, including the rate, duplex mode, and
After configuring interface split or merge on an interface, you need to save the configuration and restart the switch to make the configuration take effect. The original configuration on the interface will be lost.
Example for Configuring a Layer 3 Switch to Work with a Router for Internet Access Layer 3 Switch Layer 3 switches provide the routing function, which indicates a network-layer function in the OSI
When using switches, we may encounter many confusions, such as what types of optical modules are needed for different models of Huawei switches, and how to resolve issues encountered
Evaluate ODVA fiber optic connectors for FTTA, 5G-Advanced, and industrial edge networks. Analyze IP67/IP68 ratings, deployment trade-offs, and procurement criteria.
The configuration personnel can pre-configure the transmission medium type on optical interfaces and configure functions on the interfaces. These functions take effect after the installation
This document describes the principles and configurations of interfaces and provides configuration examples.
If the local combo optical interface is connected to a remote optical interface, configure the combo interface to work in fiber mode. If the local combo interface is configured to work in a different mode
You can configure the rate and duplex mode of an Ethernet interface working in either auto-negotiation or non-auto-negotiation mode. In auto-negotiation mode, interfaces at both ends of
