Hi Guys!
Let me share my experience.
I've got C3750E with few VLANs. 1 VLAN for wifi clients an cisco standalone AP (no WLC in use), and 1 VLAN for wired clients.
I struggled to set up chromecast for a year, I didn't find a good example until last night I found an example So I would like share this and helps for anybody.
