Model: EAP245  
Hardware Version: V4
Firmware Version: 1.2.1

Hello,

 

I just replaced my old AP (very old, and other brand) with EAP245.

 

VLAN configuration is very simple :

- No dedicated Management VLAN

- VLAN 1 (LAN) for internal use

- VLAN 10 for guests

- Port configuration on switches : Trunk ; 1 Untagged ; 10 Tagged

- There is a DHCP server in each VLAN

 

 

SSID :

- Private on VLAN 1

- Public on VLAN 10

 

With old AP, this simple configuration was working fine.

 

 

I installed Omada SW controller (version 5.13.22) and configured the AP, using identical cables and switch configuration as before (nothing changed).

 

Discovery and management of AP has been done without any problem.

The 2 SSID are correctly broadcasted, and users can connect to both.

Public SSID (linked to VLAN 10) is working fine.

 

 

However... there is a major problem with Private SSID (VLAN 1).

The users can connect to the AP (authentication OK) but... they never received an IP.

Even using a fixed IP (in VLAN 1) on PC, it is impossible to reach any IP (even in VLAN 1).

 

The AP can be pinged in VLAN 1.  But it is the only possible communication.

 

 

Could you please help to solve this issue ?

 

Thanks in advance.

"Port configuration on switches : Trunk ; 1 Untagged ; 10 Tagged"

"SSID (VLAN 1)"

 

Remove the VLAN 1 setting from the SSID. The port with PVID=1 and untagged in VLAN 1 will do the job of placing untagged frames in VLAN 1.

How did you set the VLAN ID for SSIDs? 

To make the wireless VLAN work properly for Omada EAP, both the Router and the Switch should be VLAN capable.

If the network topology is like "Router (Port1) ----(Port2) Switch (Port3) ---- EAP )))((( SSID1 vlan10, SSID2 vlan20",

Then the Port1, Port2, and Port3 should all have VLAN10 & VLAN20 tagged.

Hi,

Thanks for answering.

 

VLAN for SSID have been set in Settings -> Wireless Networks -> WLAN :

  • SSID Private : Edit -> Advanced Settings  :  VLAN Enable : 1
  • SSID Public : Edit -> Advanced Settings  :  VLAN Enable : 10

 

 

LAN ports are always : Trunk ; VLAN 1  Untagged PVID ; VLAN 10 Tagged

 

Routers and Switches are VLAN capable, it was working fine on both VLAN 1 week ago with the old AP.

Did you have management vlan set? Any ACL? EAP ACL? Gateway ACL? 

It should be easy to deploy it as the article mentioned:

No, it is a very simple and small network.

 

No ACL, no management VLAN.

 

 

Yes, I already followed this tutorial.

But, there is no mention of default VLAN (untagged) used in SSID.

 

And this default (untagged) VLAN 1 is the core of my problem.

Hi,
Thanks for the answer.

 

You are right, it seems to be a very stupid mistake...

 

I try immediately.
