Josh, make sure you have the "switchport port -security" enabled at the global level.  Setting the configuration on the port alone will not work until it is set globally. Thanks, Victor
Hello, we have always been a Cisco shop but are giving Dell switching a try.  We are test driving a 1548P and one thing we can't figure out is how Dell portsec with mac sticky works on the Dells.  Maybe this isn't supported with the 1548?
