Keep in mind, the assignment or order in which the virtual mac addresses are assigned in the above example has nothing to do with the WLAN IDs that are configured in the WLC. NOTE: The VIRTUAL MAC ADDRESSES get reused by the access point on both the 2.4GHz and the 5GHz radios. 11 and so on.ĥGHz – Notice the sixteenth SSID ‘16’ is assigned the BASE RADIO MAC ADDRESS A9:10. Note: The access point base radio mac address ends in A9:10.Ģ.4 GHz – Notice the first SSID ‘01’ is assigned the BASE RADIO MAC ADDRESS A9:10. I then fired up AirMagnet WiFi Analyzer Pro to conduct a capture. Cisco WLC access points have a limit of 16 SSIDs on each radio. I then enabled both the 2.4 GHz and 5 GHz radios. You can find the base radio mac address under WIRELESS->Select Access Point Pay very close attention to the 2.4GHz and 5 GHz radios and BSSIDs. What is interesting is how the virtual MAC addresses are selected. This allows for wireless network segmentation as well as for wireless clients to communicate via LAYER 2 with each access point BSSID.Ī Cisco access point takes the base radio mac address and then virtualizes the mac address as additional SSIDs are added. This is a quick blog post on how Cisco uses the VIRTUAL MAC ADDRESS for BSSID(s).Īs you add SSIDs (Service Set Identification(s)) to an access point each BSSID (Basic Service Set Identifier) receives a virtual mac address.
