GS324TP S350 unable to obtain IP from unifi USG3 and UAP-AC-PRO
Hello everyone, I have been trying to configure multiple vlans to be accessible on my unifi AP. I read similar post where people indicated they were successful, however I have not been lucky enough to be successful. Here is my harware info. I will appreciate if anyone can help me troubleshot/setup. thanks in advance.
1 Unifi USG-3
1 UAP-AC-PRO
1 netgear GS324TP S350
USG3 port1 ---> netgear GS324TP Port1
UAP-AC-PRO ---> netgear GS324TP Port5
USG3 network and wireless config
Networking
internetofthings VLAN10 172.16.10.1/24
SecurityCam VLAN20 172.16.20.1/24
VLAN1 192.168.2.1/24
Wireless Networks (inherit the above network IP)
internetofthings ---> internetofthings network
SecurityCam ---> SecurityCam network.
Netgeat GS324TP
Port 1. Untaged VLAN ID 1 / Taged VLAN ID 10 and 20
Port 5. Untaged VLAN ID 1 / Taged VLAN ID 10 and 20
Port 1 to 26 : untaged VLAN ID 1
The access point is able to see the device attemtping to connect, but it is unable to obtain IP address. I am sharin couple screen capture for reference.

Based on the NetgearGS324TP-VLANPVIDPORT.png and assuming USG and AP are connected to the two ports configured accordingly, there isn't anything wrong with your VLAN config. Back to the UniFi config I'd say...
PS. The in-line images are under mandatory moderation, so it will take a while until visible.

Hi Jelon71,
I have a very similar problem using a Unify Dream Machine and a GS348T switch + a Unify U6-Lite AP.
The AP plugged into the Unify Dream Machine works perfect, when I plug it into my switch it does no longer.
My assumption is that the DHCP requests do not get through, but I 'm just not sure what I need to configure .
My config on the switch VLAN looks exactly like yours.
Is there any other traffic that needs to be allowed on the switch?
Did you find the problem?
Thanks
Dietmar

Where exactly, which VLAN, ...? The basic untagged (?) UniFi management VLAN or any other VLAN accessed by some dedicated SSID(s)?

Hi schumaku,
I have 3 WIFI Networks , lets call them WIFI_PRIVATE, WIFI_GUEST, WIFI_IOT and according to these 4 VLANs
WIFI_PRIVATE = 5 (DM Port 1 - Switch Port 1) PVID 5 Tagged 5
WIFI_GUEST = 15(DM Port 2 - Switch Port 15) PVID 15 Tagged 15
WIFI_IOT = 35(DM Port 3 - Switch Port 20) PVID 35 Tagged 35
Management LAN = 1(DM Port 4 - Switch Port 30) PVID 1 Tagged 1
AP = Switch Port 31 - Tagged for 1,5,15,35 and PVID 1
The WIFI Networs all do have wired network as well.
And there are 4 DHCP Servers configured in my Dream Machine
I use 4 uplink cables from my Dream Machine to the switch . One for each VLAN (I know this is not needed, but made it easier for mybrain 🙂
The switch is configured on VLAN 1 to be management VLAN
My thought was, that the AP needs to acquire an IP Address, which should be on the Management VLAN, as this defaults to 1 (I assume) it should come through from Port 31 to 30 and should reach the DHCP there.
Then it spans the WIFI and communicates on the tagged Networks according to the LAN Config that is used on each WIFI.
But the AP just tries to communicate with my DM and then fails.
As I said, I assume it is the DHCP, bur maybe it is something that I don't see yet.
Any idea what I do wrong?
Thanks

Best guess (at least by default) the UniFi management network is untagged - so keep the port to the AP untagged for the management VLAN 1. PIVD is already set to 1, so now you should be ready to run.

Hi schumaku,
thanks a lot, now it works. I had to switch off my firewall rules between the networks and need to figure out how they need to be set, but this is a different story.
If there is a hint how to allow management traffic like DHCP requests m but no other traffic, please let me know 🙂
Thanks a lot

Hi schumaku,
seems my success was called too early. IAfter rebooting the AP the problem stays as I've seen it before.
Here my question.
The DM does not TAG VLAN 1 , and it is impossible to configure it for VLAN 1. Would it be a good decision to configure the DM Management LAN with VLAN 2. The switch needs to have the Management VLAN to be tagged. If the switch defaults to 1 and DM to no Tag, would they even talk together? I assumed the PVID and an untagged Port would solve this, but does it?
Thanks

Lot's of training seems to be required here - most general VLAN and Ubiquity specific - very few Netgear switch related.

Yes, this is siilar to what I mentioned ref. the UniFi APs, too.
Configure the ports where you are connecting the DM and the APs for VLAN 1 [U]ntagged and PVID 1. This makes the switch sending VLAN 1 frames untagged, the PVID 1 assigns incoming untagged frames to the VLAN 1. (the second is about the only Netgear switch specific thing).

No. Where is this information coming from? The config says the switch does make use the VLAN 1 for the management. How the management access comes to the switch is not relevant.
The VLAN 1 traffic be on a trunk port where the VLAN 1 it [T]agged (not just on the switch, also the connecting device to this network link - this is what one would typically do if multiple VLANs are transported on the same link - unless devices require one VLAN untagged), or it can be VLAN 1 frames untagged, the PVID 1 assigns incoming untagged frames to the VLAN 1 as explained.

Hi schumaku,
thanks for filling my knowlege holes 🙂 and helping me out here.
I do have, the DM and AP on PVID 1 and [U]ntagged for VLAN1
All the other VLANs are Tagged on both ports, my assumption was that this would be a transparent way through the switch, as a direct connect to the AP to DM on the same DM Port works fine.
The AP continuously restarts with "Isolated/Restarting/RFScanning" state. The IP seems to be assigned now.
I'm lost, and the guy I pay for handle my Network suggests to buy a new switch from unify. I don't want to do this. 😞
Is there a diagram, video or anything out there explaining how the AP and DM communicate, and what kind of traffic needs to be enabled in order they could find and like each other?

Yet another issue that is not a Netgear problem - your config looks fine based on the description, but I would double check things 8-)
Reads to me your APs can't reach the UniFi controller - this is either a the UniFi Cloud Key or the DM - is why ever not reachable, or does hang around in another VLAN and/or IP subnet. Again something that should reside on an untagged VLAN 1 by rule of thumb. Also check the APs (without a tagged management configured - just in case) VLAN and the controller are really on the same subnet (and VLAN).
