This guide explains how to remove a static IP binding, clear ARP caches, and perform network checks such as loop detection, CPU usage monitoring, and log inspection to resolve persistent IP usage errors on Huawei equipment.
This guide explains step‑by‑step how to enable the Telnet service on a Huawei switch, set up a time‑range, create a basic ACL that permits a single host, and apply the ACL to the VTY lines to restrict access.
This guide explains how to configure Huawei IPSG on S-series devices by creating user‑bind tables and enabling IP source checking, providing both static and dynamic configuration examples with VLAN, DHCP snooping, and interface settings.
This guide explains how to create a permanent port group on a Huawei aggregation switch, add ten access‑switch interfaces to it, set the ports as trunk, allow VLAN20 traffic, and verify the configuration using display commands.
This guide provides a step‑by‑step configuration for setting up an L2TP VPN on Huawei equipment, covering ACL rules, IP pools, user authentication, interface settings, virtual templates, PPP parameters, static routing, and related commands.
This guide demonstrates how to create Huawei router ACLs and traffic policies that deny traffic from a given IP subnet and block TCP ports 25, 110, and 80, applying the policies inbound on a GigabitEthernet interface.
The article explains how to identify the MAC address and switch port of a device causing an IP conflict on a Huawei S5700 by disconnecting the server, ping testing, telneting to the switch, and executing a specific ARP display command.
This guide explains how to delete a static DHCP binding on Huawei's GigabitEthernet 0/0/2 interface, troubleshoot the "static‑MAC user" error, and verify the removal using CLI commands such as undo, reset, and display.
This guide details the step‑by‑step configuration of a Huawei device to enable web management, generate local RSA keys, activate SFTP and SSH services, upload web files, and set up HTTP/HTTPS servers with user authentication, providing commands and verification procedures.
