Problem mapping VLAN1 on a 9800-CL deployment

[CruzD]

Hi,

WLC and APs are associated using VLAN 2050. APs in FlexConnect mode, not Central Switching.

On the switches, the ports where we connect the APs are defined as native in 2050 and we tag the other VLANs.

The LAN network is in the default VLAN of the switches.

There are two WLANs defined:

- Guest WLAN: in VLAN8, which receives DHCP from the router and works correctly.

- Work WLAN: in VLAN1, it does not work correctly. The wifi users connect, but they go out with IPs from VLAN2050, the same as the APs.

We have defined 2050 as native to the APs and defined 1 and 8 but it seems that VLAN1 cannot be tagged as "outbound" from the AP to the switch.

  - I would advise to not VLAN1 in  your design and use another one,

I am 100% with @Mark Elsen, but this behavior could be "works as designed" based on your Policy-Profile config:
