GPON Test Lab 2 Guide

Lab 2: Create a Basic L2 Network with VLANs

This guide details the steps to establish a basic Layer 2 network utilizing VLANs for network segmentation, specifically for staff and guest management.

Network Topology

The network architecture comprises the following components:

• Internet connection
• Omada Gateway
• GPON OLT (Optical Line Terminal)
• GPON Splitter
• Omada PoE Switch
• Omada AP (Access Point)

The setup facilitates distinct SSIDs for staff (Staff_SSID) and guests (Guest_SSID) via Omada APs.

VLAN and IP Addressing Scheme

The network is segmented using VLANs with associated IP addressing and gateway configurations:

• VLAN 10 (Staff): IP Pool 192.168.10.1/24 (Gateway)
• VLAN 20 (Guest): IP Pool 192.168.20.1/24 (Gateway)
• VLAN 1 (Default): IP Pool 192.168.0.1/24 (Gateway)

Test Items

• Create networks for VLAN 10 and VLAN 20, and configure corresponding DHCP pools.
• Configure the GPON OLT on the Omada Controller.
• Verify network connectivity and test performance.

Configuration Steps

Step 1: Create Networks

• Staff Network: Create VLAN 10.
• Guest Network: Create VLAN 20.

Step 2: Configure GPON OLT

Step 2.1: Create VLANs

• VLAN 10: [Staff VLAN]
• VLAN 20: [Guest VLAN]

Step 2.2: Configure Line Profile

• Create a T-CONT profile.
• Create a T-CONT.
• Create two GEM ports: GEM port 1 for VLAN 10, GEM port 2 for VLAN 20, and GEM port 3 for VLAN 1.
• Create the GEM mapping rule: Map GEM port 1 to VLAN 10, GEM port 2 to VLAN 20, and GEM port 3 to VLAN 1.
• Note: VLAN 1 is configured as untagged in this test. Ensure the untagged option is selected.

Step 2.3: Create Service Port

• Tip: Locate and record the ONU ID; it will be used for Service Port configuration.
• Create Service Port for Staff Network: Map C-VLAN 10 to S-VLAN 10 with Tag Action set to 'Transparent'.
• Create Management VLAN: Map C-VLAN N/A to S-VLAN 1 with Tag Action set to 'Default'.

Step 2.4: Configure GPON Auto Authentication

• Select the previously created Line Profile, named GPON_lab.

Step 2.5: Activate ONU

• Deactivate and then reactivate the ONU.
• Check the service ports to ensure they are all Active.
• Follow these steps to configure other ONUs as needed.

Step 3: Configure the Switch

• Create a switch profile for the Staff Network.
• Create a switch profile for the Guest Network.

Step 4: Bind SSIDs with VLANs

• Bind the Staff SSID (Staff_SSID) with VLAN 10.
• Bind the Guest SSID (Guest_SSID) with VLAN 20.

Verify the Result

• Connect a device to the Staff SSID and verify that it obtains an IP address in the 192.168.10.x range.
• Connect a device to the Guest SSID and verify that it obtains an IP address in the 192.168.20.x range.
