I have one Cisco SF300-24P 24-Port and three Cisco WAP561. I created a guest wireless network on all the WAP561 on VLAN2. I created VLAN 2 on switch and all ports on the switch are set to trunk. My understanding is if port is on trunk mode if will flow traffic to all VLANs but Guest wifi is not working. When I connect to it I'm not getting a IP address- do I have to create a DHCP pool for Vlan 2?
