Two ssids in one Dot11Radio interface

Question

Hello,
Whilst configuring CISCO867-W router I have encoutered the following problem.
On built-in access point I have one Dot11Radio interface. Is it possible to have two ssids associated with two different vlans on one interface? If yes, how to do it? If no, is there any solution to have two separated wlans on an access-point with one Dot11Radio?

Answer 1

Of course you can have two wlans associated with two different vlans on the same radio interface.
Here is a simple example on how to it?
on the router the most important thing you have to make sure that the interface
Wlan-GigabitEthernet0 is configured as trunk and allowing the vlans mapped on the ssids defined under the radio interface of the embedded AP. Also you have to make sure that dhcp pools have been defined for both vlans.
Assuming that you have two ssids:
ssid1 & ssid2  mapped to vlans 1 and 2 consecutively. vlan 1 has been defined as the native on the trunk defined on
Wlan-GigabitEthernet0
AP(config)#dot11 ssid ssid1
                #authentication open
                #vlan 1
               #exit
AP(config)#dot11 ssid ssid2
               #authentication open
               #vlan 2
               #exit
AP(config)#interface dot11radio 0
              #ssid ssid1
              #ssid ssid2
              # no shut
              # exit
AP(config)#int dot11radio 0.1
               #encapsulation dot1q 1 native
               #bridge-group 1
               #exit
AP(config)#int dot11radio 0.2
               #encapsulation dot1q 2
               #bridge-group 2
               #exit
AP(config)#int gig 0.1
               #encapsulation dot1q 1 native
               #bridge-group 1
               #exit
AP(config)#int gig  0.2
               #encapsulation dot1q 2
               #bridge-group 2
               #exit
