Yes, you can have different VLANs on wired ports of AP302W.
I've run lately installation (still not in production), where I am using those APs managed by Cloud IQ.
I have set VLANs for VoIP and SmartTV on ETH1 and ETH2, respectively; ETH0 is a trunk port.
In Cloud IQ you have to define Network Policy and assign it to AP during onboarding.
Within the policy you have to define device template and port types.
Then you just assign port type to specific wired port of AP302W.
Remember to set port type for AP302W uplink port as a trunk, carrying all VLANs (including those used for WiFi service).
I think it could be done in XCC environment as well.
