Regrettably, these links no longer work. (They vector off to a ExtremeNetworks page.) The original blog.aerohive.com <http://blog.aerohive.com/> page still exists, though: https://blog.aerohive.com/author/davidcoleman/ <https://blog.aerohive.com/author/davidcoleman/>

Has anybody found current links to these posts? Thanks.
