We have WLC and layer 3 switch and a lot APs which are connected to the switch with vlan20 access port. The users can get ip address from dhcp pool (10.0.20.0/24) located at the switch after connecting to these APs. Now we have the second dhcp pool(10.0.30.0/24//vlan30) located at the switch too. Is this possible for users to get ip address from the second dhcp pool if we create second ssid? So the first ssid is for user to get ip address from first dhcp pool, and second ssid is for second dhcp pool. or can you send a link? Thank you!
Yes, what you are proposing should work. Your access points will tunnel both vlans to the controller. Access point does not need to be in the same vlan as the users.
Are the APs and WLANs in local or FlexConnect mode? If they're in FlexConnect mode, you'll need to create WLAN-to-VLAN mappings to tell the APs which VLAN to tag an SSID onto. The port where the AP connects needs to be a trunk and allow the VLANs you want to use.
