There's a script built into AMP which allows you to import a .csv file to correlate a username to a MAC address. To use the file:
1. Create a .csv file with data in this format:
2. Use WinSCP (http://winscp.net/eng/index.php) to copy the file to AMP. I'd recommend copying it to the /root directory or the /var/airwave/custom directory if it exists.
3. Run dos2unix to get rid of any Windows-style carriage returns in your .csv file:
# dos2unix /root/MyUsers.csv
4. Execute the script:
# import_usernames_mac /root/MyUsers.csv
