Hello,

I'm sorry for my English.

This text is translated by Google Translate.

I have an Omada OC300 on the LAN with an IP address of 192.168.2.1/24.

The DHCP service is a Windows Server for the LAN network.

My router (Proximus provider - Belgium) has a network port with VLAN 20:

- IP 192.168.20.1

- DHCP 192.168.20.50 to 192.168.20.100

The first SWITCH (SWITCH01-CAVE) is configured for VLAN20 on port 2. This is connected to another Cisco switch.

This works great for guest WiFi with a portal.

The building is big! 3 network cabinets!

I have two other switches (SWITCH02-GRENIER and SWITCH03...) also connected to a Cisco switch.

WiFi LAN works! BUT the guest WiFi is not working, it is not getting an IP address from VLAN20!!!

How should I declare VLAN 20 on the other two SWITCH?

Merci 😉

Paul
