Tip #7: Create a range of Cisco7970 MACs

with 2 comments

To be able to add Cisco7970 IP Phones as plug-n-play devices in the LinuxMCE system you have to define a range of MAC addresses on the Cisco7970 device template. There is an utility to do that – /usr/pluto/bin/convert_mac.

MAC address is six groups of two hexadecimal digits, separated by hyphens () or colon (:). The first three groups identify a maker. You leave them and fill the rest by 0 and F. For example, if MAC is 00:16:78:CD:01:D8 its range will be 00:16:78:00:00:0000:14:69:FF:FF:F. Now using convert_mac we can get correct data for the device template:

/usr/pluto/bin/convert_mac 00:16:78:00:00:00
/usr/pluto/bin/convert_mac 00:14:69:FF:FF:FF

Finally, put those values into text fields on the device template. Find more info and pictures here.
