How to use the core switch of Huawei cabinet switchboard

Using a Huawei core switch involves proper physical installation in the cabinet, configuring VLANs and interfaces, setting up VPN instances, and establishing routing protocols like OSPF for network connectivity.Physical Installation in the CabinetPrepare the Cabinet: Ensure the cabinet has proper AC (176–264V, 50/60 Hz) or -48V DC power supply and adequate ventilation for heat dissipation .Install Guide Rails and Cable Trays: Move and secure cable trays and guide rails to the designated slots for the core switch and other devices .Mount the Core Switch: Place the switch on the guide rails, push it until the mounting ears attach to the cabinet bars, and connect the power cables .Arrange Devices: Install smaller devices at the bottom and use filler panels for spacing. Ensure proper alignment with other network devices like routers, servers, and firewalls .Basic Configuration StepsAccess the Switch CLI: Connect via console or SSH and enter system view mode to start configuration .Configure VLANs: Create VLANs for interconnection with other devices:CodeCopy vlan 10 vlan 100 Then create VLANIF interfaces and bind them to the VLANs .Set Up VPN Instances: Create a VPN instance to isolate public network routes from internal routes:CodeCopy ip vpn-instance vpn1 interface Vlanif100[Quidway-Vlanif100] ip address 192.168.1.1 255.255.255.0[Quidway-Vlanif100] vpn-instance vpn1 This ensures secure routing between the core switch, BRASs, and firewalls .Configure Interfaces: Assign interfaces to VLANs and connect to BRASs, firewalls, or other switches:CodeCopy interface GigabitEthernet1/0/0[Quidway-GigabitEthernet1/0/0] port link-type access[Quidway-GigabitEthernet1/0/0] port default vlan 10 Set Up Routing Protocols: Configure OSPF or static routes to enable connectivity to the egress network:CodeCopy ospf 1[Quidway-ospf-1] area 0.0.0.0[Quidway-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255 This allows the core switch to manage traffic between internal and external networks .Verification and MonitoringCheck Interface Status: Use display interface to verify connectivity and operational status .Check VLAN Configuration: Use display vlan to confirm VLAN assignments and bindings .Monitor Routing: Use display ospf peer or display ip routing-table to ensure proper route propagation and network stability .Additional TipsAlways document VLAN IDs, IP addresses, and interface assignments to avoid conflicts.Use modular installation to allow future expansion of the cabinet.Follow Huawei's official manuals for firmware-specific commands and advanced features . By following these steps, you can successfully install, configure, and operate a Huawei core switch within a cabinet switchboard, ensuring secure and efficient network connectivity.
