As seen in the below image:Īs SSID's increases on 802. I notice that the devices listed on the wireless system listed a MAC address that is supposed to be the router but it is not the same that is on the router case. This stands as the BSSID for the first SSID being broadcasted on 802.11b/g radio. When joined back with OUI, it looks as below: XOR the first four digits with 8 i.e 1000:Ĩ. Drop the first character from the UAA, i.eĤ.
To find a vendor/manufacturer from an OUI, please visit:ģ. Organizationally Unique Identifier (OUI) is a 24-bit number that uniquely identifies a vendor, manufacturer, or other organization globally or worldwide. Step 2: Now, in order to know what is the Wireless NIC’s MAC address, we can navigate to the Network & Internet Settings, and then right-click on the Wifi option, from there select the properties option. Next, remove the first six(6) characters from OUI from the wired MAC address. Step 1: Firstly, go to open a command prompt shell, and then type getmac in order to see the Transport Address as well as MAC Address. As AP-135 come with two ethernet ports, then the MAC address of second ethernet port would be d8:c7:c8:cc:43:2 (4+1) = d8:c7:c8:cc:43:2 5. Lets take one of the wired MAC address shown in the above image. If you have configured, then either look physically on the AP or we can take it from "show ap database long" CLI command, as shown below: With an example, lets understand how the BSSID is derived from the wired MAC address of an AP:īy default, the wired MAC address of an Access Point appears as a AP name. Two ethernet ports gives double the amount of available MAC addresses than one port. Underlying limitation is that each BSSID needs a MAC address that is derived from the ethernet port MAC. Total BSSID's including b/g and a radio = 16 The fact that we can share data with others, access online content from anywhere in the world, and do all of it. SSIDs per radio: (Number of Ethernet ports * 16) / number of radios on an AP.įor example, for AP-105 which is a single ethernet and dual-radio AP: The internet is really a brilliant and innovative thing when you think about it. So, as we know Aruba Access Points are capable of broadcasting multiple WLAN's on a single radio (b/g or a) and thereby the number of SSID's per radio of an Access Point: When a wireless client associates to an AP, it sends traffic to the AP’s Basic Service Set Identifier (BSSID) which is usually derived from Access Points MAC address. Environment : This article applies to Aruba Mobility Controllers, Aruba Campus and Instant Access PointsĪPs advertise WLANs to wireless clients by sending out beacons and probe responses that contain the WLAN’s SSID and supported authentication and data rates.
