I am setting up a 2504. I would like to set up 1 WLAN to connect directly to an ISP switch to use as a PUBLIC network. I configured port 2 on the 2504, set up interface with an address, then created a WLAN and SSID. (Port 1 is set up as internal and connects to the Catalyst 3850) It seems to work. When I change it to different VLAN ID, it does not work. Although port 2 is directly connected to the ISP device, do I have to make any changes on the catalyst for this to work or am I overlooking something. Thanks.
