Adding VLAN to the optical port of Huawei switch

You can add a VLAN to an optical port on a Huawei switch by configuring the port as an access, trunk, or hybrid interface and assigning the desired VLAN ID using CLI commands.Step 1: Access the Switch CLIConnect to the Huawei switch via SSH, Telnet, or console port. Log in with your administrative credentials to access the CLI . Enter system view mode:CodeCopysystem-view Step 2: Create the VLAN (if not already created)Check if the VLAN exists or create it:CodeCopyvlan 10 This creates VLAN 10. You can also create multiple VLANs in batch using:CodeCopyvlan batch 10 20 30 VLAN IDs range from 1 to 4094, with 0 and 4095 reserved .Step 3: Configure the Optical PortDetermine whether the optical port will be an access port (single VLAN) or a trunk/hybrid port (multiple VLANs).Access Port (single VLAN)CodeCopyinterface GigabitEthernet 0/0/1 // Replace with your optical portport link-type accessport default vlan 10 This assigns VLAN 10 to the port and ensures untagged frames are tagged with VLAN 10 .Trunk Port (multiple VLANs)CodeCopyinterface GigabitEthernet 0/0/1port link-type trunkport trunk allow-pass vlan 10 20 30 This allows multiple VLANs to pass through the optical port, with frames tagged accordingly .Hybrid Port (mixed access and tagged VLANs)CodeCopyinterface GigabitEthernet 0/0/1port link-type hybridport hybrid vlan 10 untaggedport hybrid vlan 20 tagged Hybrid mode allows one VLAN to be untagged (default) and others to be tagged, useful for connecting devices that need multiple VLANs .Step 4: Verify ConfigurationCheck VLAN assignment and port status:CodeCopydisplay vlan 10display interface GigabitEthernet0/0/1 These commands show which ports are members of VLAN 10 and the operational status of the optical port .Step 5: Save ConfigurationEnsure the configuration persists after a reboot:CodeCopysave Confirm when prompted to write the configuration to the startup file .NotesUntagged frames on access ports are automatically assigned the port's default VLAN (PVID).Tagged frames are required for trunk or hybrid ports to carry multiple VLANs.Optical ports are treated the same as Ethernet ports in terms of VLAN configuration on Huawei switches .By following these steps, your optical port will be successfully added to the desired VLAN, supporting either single or multiple VLAN traffic as required.
