Could somebody explain me how to calculate a range of MAC addresses for CISCO phone? MAC is 0123456789ABCDEF. I tried to type it in the two fields but it wasn't stored.

Thanks in advance.

Use
Code:

/usr/pluto/bin/convert_mac XX:XX:XX:XX:XX:XX

and it will show you a long number.

So if your phone's mac is 12:34:56:78:9A:BC then it's in mac range 12:34:56:00:00:00 - 12:34:56:FF:FF:FF.

Which converted to numbers mean : 20015990439936 - 20016007217151

These are the numbers you should add to your device template.
