My DHCP is handled by the MS350. Under Switching - Configure - Routing & DHCP I have created multiple interfaces.
For example:

I want clients connecting to the "WiFi" to get IP addresses from the DHCP server set up on VLAN 80. Currently they are only getting IP addresses from VLAN 1.
Under the SSID settings, I tag VLAN 80.

All of my switches are connected using SFPs. Those ports are configured with like this:

VLAN 99 is my management VLAN, all switches are configured this way. What do else do I need to configure before pulling the trigger on the SSID setting?
