VLAN ID means tagging?

Hi, I’m trying to assign VLAN IDs to my OAW-AP1101 WLANs but first of all I want to know if setting a VLAN ID means tagging the devices in the WLAN or not

Jorge doesn't help me much the APs (on VLAN1-Default) work fine and are connected to the M4100-D12G as untagged. The APs, in addition to the management LAN (as mentioned above VLAN1) have other SSIDs, each configured with its own VLAN ID (which in my opinion, and the purpose of this question, means tagging all the devices contained); these other SSIDs are also linked to the M4100-D12G as tagged but I can't "communicate" with them (and vice versa)

Hi! First of all you need properly configure port on switch - make it Trunk mode working with default WLAN1 and allow tagged traffic from required VLAN's (add VLAN membership to the port)

It depends. There AP needs its network settings (IP, Mask, GW, OV2500 IP address if present, DNS servers, etc.) That information is obtained using the untagged/native vlan. Then, you have to configure the SSID or UNP/ARP (User Network Profile/Access Role Profile), and map then entire SSID to a VLAN, that can be untagged/native or tagged. Or you can use the ARP schema to map a set of N ARPs to different M VLANs (whatever N and M, with N=M as the case where each ARP is linked with a different VLAN) VLAN-ID = 0 means linked with untagged/native VLAN in that port. Any other number means the traffic will be tagged with such 802.1Q VLAN-ID.

Untagged/native VLAN can be use for both management and service traffic.

Let me know if that helps, Jorge

I'll assume you're working on Express mode. The AP, according to the provided information, will tag the traffic of each SSID in a VLAN. For instance, let's suppose that for SSID-100, the AP will place the traffic in the trunk-Ethernet port with VLAN-ID 100. So other devices in VLAN 100 or, if IP routing is enabled in the network other VLANs as well, should see the STAs (wireless stations). Setting a value in VLAN-ID, other than 0, will TAG the traffic.

ok, this means (correct me if I'm wrong) that setting VLAN ID on the AP I'm going to tag all the traffic generated by the devices of a specific SSID. my question was precisely this, because the devices connected to the various SSIDs do not have the possibility to specify a tag there is probably a passage that I don't understand, because the APs are connected to a GS108PEv3 (to take advantage of the PoE ports) and the latter is attached to the M4100-D12G. the M4100-D12G has a port (11, tagged) that connects the GS108PEv3 (8, tagged) and the latter has 3 PoE ports (also tagged) to which the APs are connected

Exactly, the AP is the one that will add (tag) the traffic with the VLAN-ID settings. End-Devices (STA) are not aware of tagging, it is transparent for them. Your setup seems to be ok... The GS108 should have 3 tagged ports with PoE for the APs, and a Trunk port (8) tagged with all the VLANs, conneced to M4100 tagged port 11, with the same VLANs. In any case, if you need all devices to be able to connect with others, you will need to enable L3 (Inter-VLAN routing) in the M4100 (not very familiar with the brand, but seems to support it)

Thanks Jorge, resolved M4100 has Inter-VLAN Routing enabled by default. for some strange reason i forgot to tag PoE ports :) Thanks again

Perfect !!!
