Huawei Core Switch Configuration Process

Huawei core switches can be configured by logging in via console or web interface, setting management IP, creating VLANs, assigning ports, configuring trunk links, and establishing default routes.

Initial Access and Login

1. Connect to the switch using a console cable, SSH, or Telnet. If using a PC without a serial port, a USB-to-serial adapter may be required .
2. Log in with the default credentials (commonly admin / [email protected] for V200R010C00 and later). Change the password immediately for security .
3. Verify the software version using the display version command to ensure compatibility with configuration commands .

Management IP Configuration

1. Enter VLAN interface mode for management, usually VLAN 1:

   interface Vlanif1ip address 172.20.99.38 255.255.255.0

2. Set the default gateway for external network access:

   ip route-static 0.0.0.0 0.0.0.0 172.20.99.1

3. Exit interface mode with quit and save the configuration to persist after reboot .

VLAN and Port Configuration

1. Create VLANs for different network segments:

   vlan 10vlan 20vlan 30

2. Assign ports to VLANs:
   • For access ports (end devices):

     interface range GigabitEthernet0/0/1 to 0/0/25port link-type accessport default vlan 10quit

   • For trunk ports (inter-switch links):

     interface GigabitEthernet0/0/26port link-type trunkport trunk allow-pass vlan 1 10 20 30quit

3. Verify VLAN assignments with display vlan and interface settings with display interface .

Connecting to Access Switches and Routers

1. Configure trunk links between the core switch and access switches to carry multiple VLANs .
2. Connect the core switch to the AR router and configure the interface with the appropriate VLAN and IP settings.
3. Ensure a default static route points to the AR router for external traffic:

   ip route-static 0.0.0.0 0.0.0.0 <AR-router-IP>

User and Management Configuration

1. Create administrative users with appropriate privileges:

   local-user admin password irreversible-cipher Helloworld@6789local-user admin privilege level 15local-user admin service-type telnet

2. Enable SSH for secure remote management and disable insecure protocols if possible .

Saving and Verifying Configuration

1. Save the configuration to ensure it persists after reboot:

   save

2. Verify connectivity and VLAN functionality by testing inter-VLAN communication and access to external networks . By following these steps, a Huawei core switch can be fully configured for a small to medium-sized campus network, supporting VLAN segmentation, trunking, and external routing.
