Huawei 10 Gigabit All-Optical Switch

Huawei 10GE all-optical switches can be configured by enabling 10GE ports, applying licenses if required, mapping physical interfaces, and setting up Eth-Trunks for redundancy and high availability.

Enabling 10GE Ports

By default, 10GE SFP+ optical ports on Huawei switches operate at 10 Gbit/s. On certain models, such as the S6730-H series, you may need to purchase and activate a license to enable the maximum rate for 10GE ports. After license activation, use the following command in system view to set the port type:

CodeCopy assign port-type 25ge slot slot-id

To revert to the default 10 Gbit/s rate, run:

CodeCopy undo assign port-type 25ge slot slot-id

After applying this configuration, restart the device for changes to take effect. Always back up existing configurations before restarting, as interface settings may be lost .

Physical Interface Mapping

For all-optical deployments, especially in Passive Ethernet Network (PEN) scenarios, map the physical 10GE interfaces to logical ports. For example, on a PEN central switch:

• Insert PEN central optical modules into CFP2 interfaces.
• Connect Device1 and Device2 (core switches) to the PEN passive aggregation module using dual uplinks.
• Connect the access switch (Device3) to the PEN remote optical module via dual-LC fiber.
• Verify mappings using:

CodeCopy display device wdm-port mapping slot 1

This ensures each 10GE interface is correctly associated with its remote optical module and wavelength .

Eth-Trunk and Redundancy Configuration

To improve reliability and load balancing:

1. Create an Eth-Trunk on the stack:

CodeCopy interface Eth-Trunk 1[Sysname-Eth-Trunk1] mode manual[Sysname-Eth-Trunk1] trunkport 10GE1/0/1[Sysname-Eth-Trunk1] trunkport 10GE2/0/1

1. Configure master/backup mode for active/standby traffic forwarding.
2. Assign VLANs to the Eth-Trunk to allow traffic segmentation:

CodeCopy[Sysname-Eth-Trunk1] port link-type trunk[Sysname-Eth-Trunk1] port trunk allow-pass vlan 10 20

This setup ensures dual-homed uplinks and high availability between core and access devices .

Additional Best Practices

• Use iStack for intelligent stacking of multiple switches to simplify management and improve redundancy.
• Enable Smart Link to provide uplink backup and rapid failover.
• Regularly check interface status and port mapping to ensure optical links are operational.
• Implement security controls such as per-port authentication, VLAN policies, and DoS protection to safeguard the network .

Summary

Configuring Huawei 10GE all-optical switches involves:

1. Activating licenses and setting port types for 10GE SFP+ interfaces.
2. Mapping physical optical interfaces to logical ports.
3. Creating Eth-Trunks with master/backup or active/standby modes.
4. Assigning VLANs and enabling redundancy features like Smart Link and iStack.
5. Verifying configurations and backing up before device restarts. Following these steps ensures high-performance, reliable, and secure 10 Gigabit all-optical network deployment.
