Can Huawei switches only have their IP addresses configured via optical ports

Huawei switches can have IP addresses configured on multiple interface types, not just optical ports.

Interface Options for IP Configuration

Huawei switches support IP address assignment on several interfaces: VLANIF Interfaces: Virtual interfaces associated with VLANs can be assigned IP addresses for management and in some cases service traffic. This is commonly used for Layer 3 management on switches that operate in Layer 2/Layer 3 mode. Ethernet Management Ports (MEth/ETH): Dedicated management ports allow out-of-band management and can be directly assigned an IP address without carrying service traffic.

Service Interfaces: Physical Ethernet ports that carry network traffic can also be configured with IP addresses if the switch supports Layer 3 mode. Otherwise, the IP is assigned to the VLANIF associated with the port.

B Ports: While these ports do not carry IP traffic, they are used for initial configuration and local management before network-based IP configuration is applied.

Optical Ports

Optical ports, such as 10GE or XGE interfaces, are treated as service interfaces. You can configure IP addresses on these ports if the switch is in Layer 3 mode, but it is not mandatory to use optical ports exclusively for IP configuration.

P addresses can also be configured on copper Ethernet ports or VLANIF interfaces. Management ConsiderationsIn-band management: IP addresses on service interfaces allow management traffic to share the same link as user data. Out-of-band management: IP addresses on dedicated management ports (Ethernet management port) provide a separate channel for management, improving security and reliability.

Conclusion

Huawei switches are flexible in IP configuration. You are not restricted to optical ports; IP addresses can be configured on VLANIF interfaces, Ethernet management ports, and service interfaces, depending on the switch model and Layer 2/Layer 3 mode settings. This allows administrators to choose the most suitable interface for management or routing purposes.
