Fiber and communications infrastructure knowledge brief Published 03 Aug 2023

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Huawei switches use Eth-Trunk and 802. 1Q trunk ports to converge multiple physical links into a single logical link, increasing bandwidth, reliability, and enabling VLAN traffic across switches.

Eth-

Trunk (Link Aggregation)Eth-Trunk is Huawei's implementation of Ethernet link aggregation, which bundles multiple physical interfaces into a single logical interface. This provides several benefits: Increased Bandwidth: The total bandwidth of the Eth-Trunk equals the sum of its member interfaces, allowing higher throughput without upgrading hardware. High Reliability: If one physical link fails, traffic automatically switches to other active links, ensuring continuous connectivity.

Load Balancing: Traffic is distributed across all active links, improving network efficiency.

Configuration Steps

Check Interface Status: Ensure all physical interfaces are connected and operational using display interface brief.

Create Eth-

Trunk: Assign member interfaces to the Eth-Trunk in either manual mode or LACP mode for dynamic link aggregation. Consistency Check: Ensure all member interfaces have the same duplex mode, flow control, and aggregation mode. Mixed-rate links can be enabled in versions V200R011C10 and later.

Verify: Use commands like display eth-trunk to confirm the status and load balancing of the Eth-Trunk.

VLAN Trunk Configuration

A trunk port allows multiple VLANs to pass through a single physical link using 802. 1Q tagging: Tagged VLANs: Carry traffic for multiple VLANs.

Native VLA

N: Untagged traffic belongs to a default VLAN. Use Case: Connects switches or routers to allow VLAN communication across devices.

Configuration Steps

Create VLA

Ns: Define VLANs on both switches, e.g., VLAN 100 and VLAN 200.

Code

Copy vlan 100[Switch-vlan100] description VLAN100 vlan 200[Switch-vlan200] description VLAN200 Configure Trunk Port: Set the interface as a trunk and allow VLANs to pass. CodeCopy[Switch-GigabitEthernet0/0/10] port link-type trunk[Switch-GigabitEthernet0/0/10] port trunk allow-pass vlan 100 200 Verify: Use display port vlan to check trunk configuration and VLAN membership.

Combining Eth-

Trunk and VLAN TrunksFor converging trunks, you can assign an Eth-Trunk as a trunk port carrying multiple VLANs. This combines the benefits of link aggregation and VLAN segmentation: Create an Eth-Trunk with multiple physical links.

Configure the Eth-

Trunk interface as a trunk port. Allow the required VLANs to pass through the Eth-Trunk. Verify connectivity and VLAN reachability across switches.

This setup ensures high bandwidth, redundancy, and proper VLAN traffic segregation, which is essential for enterprise networks with multiple VLANs and high traffic demands.

Verification and Troubleshooting

Ping Test: Verify VLAN connectivity between devices in the same VLAN. Display Commands: Use display eth-trunk and display port vlan to check link status and VLAN assignments. Consistency Checks: Ensure all member interfaces of an Eth-Trunk have consistent configurations to avoid aggregation failures.

By following these steps, Huawei switches can efficiently converge multiple links into a single logical trunk while supporting multiple VLANs, improving both performance and reliability.
