Model: OC200  
Hardware Version: V1
Firmware Version: 1.7.0 Build 20200703 Rel.59609

In the Map Topology view, it shows each Omada Switch and Access Point but the devices on them is always wrong.

 

I noticed this when I added three T1500G-8T switches. Each switch randomly shows the wrong MAC addresses and devices.

 

Instead each switch shows a random and changing set of clients that are not even physically plugged in to it.

 

For example in this screenshot where the CenterSwitch shows 6 clients (number 6) but only 3 devices, and none of those devices are actually connected to that switch. That Desktop device is connected elsewhere. In other cases I do have a device connected to switch A and it shows up connected to switch B, and so on.

 

This list changes every time you reload the page.

 

Is this a known bug?

 

 

15 minutes later the BRSwitch now shows 10 devices on it and the DESKTOP has moved from CenterSwitch to BRSwitch.

 

 

And then changed again to just 3 clients only a few minutes later:

Dear @Will_M,

 

Thank you for posting the problem on the community.

 

In the Map Topology view, it shows each Omada Switch and Access Point but the devices on them is always wrong.

 

I noticed this when I added three T1500G-8T switches. Each switch randomly shows the wrong MAC addresses and devices.

That Desktop device is connected elsewhere. In other cases I do have a device connected to switch A and it shows up connected to switch B, and so on.

 

We didn't receive such feedback before, I'll forward it to the senior engineers for further test.

 

May I ask for the actual network topology of your network? What's the model and firmware version of your Omada EAPs?

@Fae Thank you for the reply!

 

Here is some more information for the network configuration.

 

Equipment In Central Rack:
Firewall: Ubiquiti Edge RouterX
DHCP/DNS: NanoPi NEO
Wireless Access Points: EAP225-Wall, EAP235-Wall, EAP245
Eth. Switch 1: Aruba S2500 24-port + 4 SFP+
Eth. Switch 2: Netgear MS510TX Multi-Gig
Controller: TP-Link OC200

3 Remote Locations elsewhere in house:
3 Eth. Switches: TP-Link T1500G-8T powered by POE port 8
Each switch has Multiple devices connected (2-4 devices per switch plus uplink/POE port)

 

Topology

The Aruba S2500 POE switch is the center of the network.

Aruba -> 10G SFP+ -> Netgear MS510TX -> Multi-Gig Ethernet Ports -> clients
Aruba -> 1G Eth -> DNS/DHCP
Aruba -> 1G Eth -> Firewall -> 1G Eth -> Modem -> ISP
Aruba -> 1G Eth(POE) -> OC200
Aruba -> 1G Eth(POE) -> T1500G-8T #1 -> 1G Eth -> clients
Aruba -> 1G Eth(POE) -> T1500G-8T #2 -> 1G Eth -> clients
Aruba -> 1G Eth(POE) -> T1500G-8T #3 -> 1G Eth -> clients
Aruba -> 1G Eth(POE) -> EAP225
Aruba -> 1G Eth(POE) -> EAP235
Aruba -> 1G Eth(POE) -> EAP245

I have a very similar issue. I've recently added a second switch to my network and the topology map is completely wrong. I have a TL-SG3428 v2.0 (fw 2.0.3) and connected to this are a TL-SG2008 v4.0 (fw 4.0.1), and a EAP245(EU) v3.0 (fw 5.0.2). Omada Controller is v5.0.30

 

Since adding the second switch, wired clients are randomly shown as connected to one switch or the other (typically the trunk port of the wrong switch).  Uplinks between the switches and between the switches and APs do not seem to be detected any more, meaning the topology map shows three distinct 'islands', when in reality everything should be connected.

 

The actual packet switching is fine.
