Calculating Cisco Meraki BSSID MAC Addresses
Learn more with these free online training courses on the Meraki Learning Hub:
Overview
Each SSID on a Cisco Meraki access point is represented as a unique MAC address known as a BSSID. While several APs in an ESS (extended service set) may advertise the same SSID, the BSSID serves as a unique identifier for clients to know which AP they are associated with. The BSSID will be seen in wireless packet captures and as the MAC address a client is associated to.
The sections below identify how these MAC addresses are calculated. When referencing the tables below, assume the wired MAC address of the AP begins with the MAC OUI specified, followed by 00:00:00. You can download a list of wired MAC addresses for your network using the Dashboard under Wireless > Access points or using the Dashboard API.
Status information about each SSID advertised by an access point, including each BSSID, can also be found using the Dashboard API or using the AP details page. Please use APIs/dashboard as a primary way to retrieve BSSID information.
No new BSSID values will be added to this article moving forward.
In the Dashboard, on any AP's summary page, click the link for "BSSID Details".
In the API, use the GET /devices/{serial}/wireless/status endpoint.
There are 15 possible BSSID combinations for each radio, starting with SSID 1 and ending with SSID 15. These SSID #'s correspond to the order of the SSIDs from left to right as seen on Wireless > Configure > SSID page on Dashboard and selecting "Show all my SSIDs".
MR12, MR16, MR18, MR24, MR62, MR66
Any given access point's MAC address may start with one of the following OUIs. Please reference the appropriate section below to find BSSID calculations for your specific access point.

The "Radio Adjustments" shown below pertain to changes made to the MAC address specific to each radio (2.4 GHz and 5 GHz). These radio-specific adjustments are not considered in the BSSID calculations. The BSSID calculations are based on the AP MAC address that can be found here.
