I have a Cisco 3750 switch with the following VLAN's
2 - Engineers
3 - Automation Dept
4 - AN Other Company
5 - Guest Access
I have an 1131ag connected to the 3750 and I have setup a dot1q trunk on the swithchport that connects to the AP.
The above guide stresses I must configure a native VLAN but I dont understand why. All traffic on the link between the AP and the 3750 will be tagged surely, where will untagged frames come from. All of the VLANS I mentioned will have an SSID on the access point. If i must configure a native VLAN can it be one that has an SSID on the AP or does it have to be a seperate VLAN. also, the guide seems to show that you set up subinterfaces on the radio interface and set the encapsulation as dot1q. why would i need to set up dot1q on the radio interface? think i'm missing the point - please could someone explain. thanks i'm tearing my hair out here!
