In distributed office, security monitoring and other scenarios, PoE switches are often deployed in computer rooms, weak current wells and other decentralized locations, and on-site management is time-consuming and laborious. Remote management can break through space restrictions and realize configuration distribution, status monitoring and fault troubleshooting. The following is a detailed explanation of the operation points and applicable scenarios of the three mainstream remote management methods.
1、 Web graphical management: zero threshold and quick start
Web management is the most intuitive remote mode, which can be operated through a browser without professional command foundation, and is suitable for initial operation and maintenance or rapid configuration of single device.
1. Pre preparation
Ensure that the PoE switch has been connected to the management network (the IP can be automatically obtained through DHCP, or the static IP can be manually configured, for example, the default management IP of our device is 192.168.1.1);
The computer and the switch are in the same LAN, or access the management network segment through VPN.
2. Operation steps
① Login interface: open the browser, input the switch management IP, and jump to the login page (our device supports account password login and USB key encryption login to ensure security);
② Core function operation:
Power supply management: in the "PoE setting" module, you can turn on/off the power supply of the specified port, set the power threshold (for example, the maximum power of a single port is 30W), and view the current and voltage data of the port in real time;
Status monitoring: The "Device Status" page displays the power consumption of the whole machine, the number of online PD devices (such as cameras and APs), and supports pop-up prompts for abnormal alarms (such as overload and short circuit);
Configuration backup: export the current configuration with one key in "System Tools" to avoid configuration loss after misoperation, or import the historical configuration for quick recovery.
3. Advantages and Applicable Scenarios
Advantages: visual interface, simple operation, support of real-time data charts (such as power trend curve), no need to remember commands;
Applicable: single/few PoE switches management, such as small office network and store security system.
2、 CLI command line management: efficient and accurate advanced operation
The CLI (command line interface) is remotely connected through SSH/Telnet protocol, suitable for high-level operation and maintenance personnel, supports batch configuration and complex function debugging, and is far more efficient than graphical interfaces.
1. Pre preparation
Turn on the switch CLI service (SSH 2.0 is turned on by default, and Telnet with low security is turned off, which can be configured in advance through the Web interface or console);
Computer installation terminal tools (such as PuTTY, SecureCRT).
2. Operation steps
① Establish connection: open the terminal tool, select SSH protocol, enter the switch IP and port (22 by default), and enter the account password to log in;
② Examples of common commands:
View PoE status: display poe port all, display power supply status and power consumption of all ports;
Configure port power supply: interface Gigabit Ethernet 0/1 (enter port 1) → poe enable (power on) → poe max power 15 (set to 15W at most);
Batch configuration: save the configuration through copy running config startup config, or modify the multi port parameters in batch with the batch config command;
③ Troubleshooting: Enter display poe alarm to view historical alarms, and ping to test the connectivity with the PD device.
3. Advantages and Applicable Scenarios
Advantages: fast command line execution speed, support script batch operation (such as configuring PoE policy for 10 switches at the same time), suitable for complex network debugging;
Applicable to: unified management of medium and large networks and multiple devices, such as computer rooms of enterprise headquarters and campus networks.
3、 SNMP centralized management: the "unified steward" of large-scale devices
SNMP (Simple Network Management Protocol) centrally monitors multiple PoE switches through NMS (Network Management System), which is suitable for the unified operation and maintenance of large networks (such as dozens of hundreds of devices), and realizes "one screen management".
1. Pre preparation
SNMP is enabled on the switch (v3 version is recommended, which supports encrypted transmission and permission control to avoid data leakage);
Deploy the NMS platform (for example, our equipment is compatible with Huawei eSight and H3C iMC, and supports the docking of customized MIB libraries with enterprise private platforms).
2. Operation steps
① SNMP configuration: Set SNMP parameters through Web/CLI, such as snmp agent sys info version v3 (enable v3), snmp agent usm user v3 admin (create administrator user);
② NMS adding device: input the switch IP, SNMP version and authentication information on the NMS platform to complete the device access;
③ Centralized management function:
Batch monitoring: view the total PoE power and online PD quantity of all switches on the NMS interface, and support sorting by region/model;
Automatic alarm: set the alarm threshold (for example, the power of a single switch exceeds 80%), and notify the operation and maintenance personnel via SMS and email after triggering;
Report statistics: automatically generate PoE power supply utilization rate, fault frequency and other reports to assist network optimization decision-making.
3. Advantages and Applicable Scenarios
Advantages: support centralized management of large-scale equipment, reduce repeated operations, timely alarm response, and facilitate standardization of operation and maintenance;
Applicable: multiple equipment scenarios such as large parks, data centers, chain enterprises, etc.
Comparison and selection suggestions of three management modes
If you are a small network O&M, Web management is preferred; If batch configuration or complex debugging is required, CLI is more efficient; If more than ten devices are managed, SNMP centralized management is the best choice.
Remote management is the core capability of efficient operation and maintenance of PoE switches. Different ways adapt to different scenarios. Our PoE switch fully supports Web/CLI/SNMP management, and has made several optimizations: the Web interface supports Chinese and English switching and custom panels, the CLI supports command completion and history query, SNMP is compatible with mainstream NMS platforms, and provides a dedicated MIB library. If you need to further understand the configuration details, you can contact technical support to obtain the Remote Management Operation Manual, or apply for a free trial device to experience the full functions.
