How to assign IP addresses to Huawei core switches

Assigning an IP address to a Huawei core switch involves configuring a VLAN interface in Layer 3 mode, setting the IP and subnet mask, and optionally defining a default gateway for management access.

Step-by-

Step Configuration1.

Access the Switch CL

I Connect to the switch using a console cable, SSH, or Telnet. Open terminal software (e.g., PuTTY or SecureCRT) and log in with administrative credentials. Enter system-view mode to enable configuration changes: CodeCopysystem-view 2.

Select the VLAN Interface Choose the VLA

N interface that will carry the management IP. For example, to configure VLAN 1: CodeCopyinterface Vlanif1 This enters the VLAN interface configuration mode. 3.

Assign the I

P Address and Subnet Mask Set the desired IP address and subnet mask for the VLAN interface: CodeCopyip address 192. 168. 1.

10 255. 255. 255.

0 Replace 192. 168. 1.

10 and 255. 255. 255.

0 with your network-specific values.

This I

P will serve as the management address for the switch. 4. Configure the Default Gateway (Optional) If the switch needs to communicate with devices outside its subnet, configure a static default route: CodeCopyip route-static 0.

0. 0. 0 0.

0. 0. 0 192.

168. 1. 1 Replace 192.

168. 1. 1 with the IP of your network gateway.

5. Exit and Save Configuration Exit interface configuration mode and save the changes to ensure they persist after a reboot: CodeCopyquitsave 6.

Verify the Configuration Check the I

P address assignment and interface status: CodeCopydisplay ip interface brief This command lists all configured interfaces and their IP addresses. You can also ping the IP from a connected device to confirm connectivity.

Additional Notes

Ensure the VLAN interface is in Layer 3 mode; by default, Ethernet interfaces operate in Layer 2 mode. Only one primary IP address can be assigned per interface, but secondary IP addresses can be configured if the switch needs to communicate with multiple subnets (up to 8 secondary IPs per interface). For core switches, it is recommended to use a dedicated management VLAN to avoid conflicts with service traffic.

Following these steps ensures that your Huawei core switch is reachable for management and integrates properly into your network infrastructure.
