PBA - MAC Address List

Hi Team,

In cnMaestro X there is an option for PBA MAC Lists. Does anyone know how/where MAC address can be added to this list?


Hi Jarrod!

Got an answer from our engineers:

Here are hte MAC list format requirements:

PBA MAC list file restrictions

A. A MAC list file must contain a single MAC address or a comma-separated list of 2…200 MAC
addresses (e.g., 11:22:33:44:55:66,88 99 aa bb cc dd,334455667788)
B. Comma-separated non-MAC address data in the file is automatically skipped during data parsing
C. Acceptable MAC address formats

  • Colon-separated octets – 11:22:33:44:55:66
  • Dash-separated octets – 11-22-33-44-55-66
  • Whitespace-separated octets – 11 22 33 44 55 66
  • Non-separated octets – 112233445566

D. A maximum of ten (10) MAC list files can be stored on the switch at any time
E. A MAC list file name must be 1…64 alphanumeric characters (plus ‘-‘, ‘_’ and ‘.’)
F. Defining a PBA MAC-LIST rule requires a MAC list file to be specified at the same time. Only currently
downloaded MAC list files can be referenced by a PBA rule
G. MAC list files that are referenced by a rule cannot be deleted

Does this answer your question? :slight_smile:

Hi Kinan,

Thank you for following this up for us, much appreciated.

How best to we go about hosting the MAC list files? Do we run a TFTP service locally and point the MAC List File Server Settings to this? If so, I assume the switches make contact locally to this TFTP service to download the lists.

Ideally it would be great to have the MAC list hosted and edited within cnMaestro :slight_smile:

Thanks again,

Hi Jarrod! another response on this :slight_smile:

If the customer already has a server set-up to support upload/download of switch images, configuration files or switch technical data, this could be used for PBA MAC list file support. Otherwise, a basic TFTP server would work just as well for this purpose. The server information would need to be configured on the switch via cnMaestro (or any other user-interface) and the identified MAC list file downloaded. A download can be initiated manually (CLI, Web) or automatically following a cnMaestro configuration push.

Hope this helps!

Best Regards
