edited August 2022 in Switch
I configured on my USG FLEX 200  2 SSID (via WebInterface)
WLAN STAFF - VLAN-ID 1 (default)
WLAN GUEST - VLAN-ID 17


USG FLEX 200 connected to GS2220-50 on port 44.
GS2220-50 connected to GS2210-48 on port 41.
Two access points WAC 6103D connected to GS2210-48  on ports 3 and 4.

Now I am facing the problem, that I can connect to "WLAN_guest" but get an APIPA adress, the DHCP does not provide an 192.168.50.0 address and I have no clue why....

Connect to SSID Staff without problem.

Any ideas what I fail to see here?
May be need configure VLAN on SW GS2220-50 and GS2210-48?
How configure vlan17 on GS2220-50 and GS2210-48 for Guest ssid?

    Hi @chr_sergey,

    Welcome to Zyxel community!

    From your scenario, I would recommend you enabling VLAN trunking on Switch ports directly, it will be easier than creating VLAN 17 on both Switches.
    GS2220 will be port 41 and 44.
    GS2210 will be port 3, 4 and 41.
    The configuration path is Advanced Application > VLAN > VLAN Configuration > VLAN Port Setup.


    Please remember to double check that VLAN 17 is in the same port group with LAN1 interface on USG FLEX 200.

    Hope it helps.

  • Hi @Zyxel_Jason.

    Your answer helped me. Thank you very much!!!!!! 
    I would like to clarify if this VLAN trunking option allows all vlans on these ports? Thanks.

    Hi @chr_sergey,

    Yes, VLAN trunking will additionally allow VLANs that are not created on Switch.
    That is, you don't need to configure again when you add other SSID VLAN on your AP in the future.

    Hope it helps.
