How to Configure VLANs on a BDCOM GPON OLT and SFU-type ONU Using CLI
Welcome to this BDCOM GPON configuration tutorial!
In this video, we’ll guide you step-by-step on how to configure VLANs on a BDCOM GPON OLT and a connected SFU-type ONU using the Command Line Interface (CLI). VLAN segmentation allows efficient traffic management for services such as Internet, VoIP, and IPTV.
Whether you’re deploying VLANs for residential users or enterprise clients, this tutorial will help you understand how to apply both access and trunk modes, configure VLAN profiles, and verify your setup effectively.
📌 What You’ll Learn:
✔️ How to create VLANs on the BDCOM OLT
✔️ How to configure uplink ports with dot1Q encapsulation
✔️ How to set access or trunk mode on GPON ports
✔️ How to create and assign VLAN profiles to ONU interfaces
✔️ How to verify VLAN configuration using show commands
📌 Important Notes:
Use access mode when all ONUs on a port share the same VLAN.
Use trunk mode when ONUs on the same port need different VLANs.
VLAN configuration for HGU-type ONUs differs from SFU-type ONUs.
Always verify MAC learning and VLAN mappings to ensure proper traffic flow.
