Before installing FlexAddress, you can determine the range of MAC addresses contained on a FlexAddress
feature card by inserting the SD card into an USB Memory Card Reader and viewing the pwwn_mac.xml
file. This clear text XML file on the SD card contains an XML tag mac_start that is the first starting hex
MAC address that is used for this unique MAC address range. The mac_count tag is the total number of
MAC addresses that the SD card allocates. To determine the total MAC range allocated, use the following
formula:
<mac_start> + <mac_count> - 1 = <mac_end>
For example:
(starting_mac)00:18:8B:FF:DC:FA + (mac_count)0xCF – 1 =
(ending_mac)00:18:8B:FF:DD:C8
NOTE: Lock the SD card prior to inserting in the USB Memory Card Reader to prevent accidently
modifying any of the contents. You must unlock the SD card before inserting into CMC.
