One of my client wants to configure VG200 (224) series in CUCM (8.6) via Kurmi.
He asked me how was calculated the address mac ports of the VG. After send him the official answer of Cisco (that is on the online help of the cucm), I figured out that the mac address of a VG224's port was 13 characters longs, as this: '10_last_mac_characters_of_the_VG' + 'magic_number' + '2_digits_of_the_ port'.
My question is: how to guess the magic_number? Someone could confirm this algorithm:
if VG is 224 then
magic_number = 4
if VG is 202 or 204 then
magic_number = 0
magic_number = 8
EDIT: I made a mistake about VG248. For this, it's a normal 12 charcaters mac address based on las 10 charcaters of the VG + port number.
