Calculating MX WAN MAC Addresses

Overview 

Cisco Meraki MX and Z-Series Security devices are physically labeled with a base MAC address that may differ from the observed MAC address of the actual interface. To obtain the actual MAC address of an interface, a packet capture is typically required. To save time, the MAC address of currently supported MX and Z-Series devices can be calculated using this article.

Locating the Base MAC Address of Cisco Meraki Devices

A MAC address is a unique hardware address that is useful for identifying a device. Cisco Meraki MAC addresses can be found using several methods.

Physical Inspection of Device

The MAC address can be found by physically locating the device information sticker on the device. An example of the information sticker on a MR16 access point is below.

Dashboard Device Page

The MAC address can also be found in the Dashboard if the device has successfully checked into Dashboard.The following image shows the MAC address on a MR33 access point listed in Dashboard:

 

 

Device Local Status Page

The MAC address can also be found by accessing the device's local status page. Reference our Local Status Page documentation for more information on accessing the local status page.

Example Calculation

MAC addresses for Cisco Meraki MX and Z-series devices can be calculated by taking the last digit of the MAC, represented as "X" in the table, and adding the offset count noted for the device.

 

Given the MAC address AA:BB:CC:06:25:E8 we will calculate the MAC for the WAN 1 interface of a MX64.

 

Checking the table, a plus 5 hexadecimal offset is indicated for the MX64.

 

The resulting MAC address is AA:BB:CC:06:25:ED as we are counting in hexadecimal.

 

For this example, this can be visually represented by the following formula:

 

0xE8 + 5 = 0xED
