VLAN spread for APs

Jump to Best Answer
  • 1.  VLAN spread for APs

    Posted May 18, 2020 10:25 AM


    we currently have 1 Moblity Controller with 20 AP.

    We created 4 SSID using 4 different VLAN (VLANs 2 - 3 - 4 - 5)

    These 4 VLANs are obviously also present on the Switch-Core and the DHCPs are on the S-Core as well.

    My question is: in order for the clients via WiFi to work correctly etc, do I need to propagate the VLANs on the Uplink between remote-switch (where the APs are physically connected) and switch-core (and also create the L2 VLAN on the remote switch)?

    Or is it enough to propagate the VLANs between Switch-core and controller?


    Thank you

    The latter (between the switch core and controller).


    The user traffic is tunneled from the APs back to the controller, then switched to the correct VLAN.
