CM820A/NA: Locating the MAC Address

« Go Back



Where can I find the MAC address on my CM820 modem?


When provisioning the modem, the Cable service provider may request the MAC address of the modem.  The label on the bottom of the CM820 contains the Media Access Control (MAC) address, a unique, 48-bit value permanently saved in ROM at the factory to identify each Ethernet network device.  To receive data service, the MAC address marked CMAC will need to be provided to the Internet Service Provider.  This document includes the following sections:

  • Locating the MAC Address on the Bottom Panel
  • Locating the MAD Address in the GUI (Graphical User Interface)

Locating the MAC Address on the Bottom Panel

The MAC address can be located on a white sticker on the bottom of the device.



Locating the MAC Address in the GUI

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter into the address box. The Status page appears.  The MAC Address will be displayed (as shown below).
