Thanks, Stan, for clarifying. Perhaps I presume, too quickly, that most schools use enterprise-class APs or switch/controller-based systems where such functionality and support for multiple BSSIDs are standard. =)
Depending on the system, there is always support for a 1:1 mapping of SSIDs to VLANs, but most support a 1 to many and many to 1 mapping, too, although it can be less than straight-forward.

To get consistent and acceptable client connectivity, the APs/WLAN controllers should support unique BSSIDs (wireless MAC addresses) for each SSID. At Emory, we are using Aruba equipment quite successfully to present multiple SSIDs for guest access and WPA/WPA2. Each SSID gets mapped to a specific VLAN and has different authentication and access rights. >>-> Stan Brooks - CWNA/CWSP Emory University Network Communications Division 404.727.0226 [EMAIL PROTECTED] AIM: WLANstan Yahoo!: WLANstan MSN: [EMAIL PROTECTED] -------- Original Message -------- From: Scholz, Greg Date: 7/10/2006 3:15 PM > I am surprised no one has brought up the issue of only being able to > broadcast one SSID.
