I am trying to ascertain if the dynamically learnt MAC address is held in the switch table when a host device is turned off or is unplugged. It mentions on CCO that the MAC address is removed when the port is shut down?
It has been my experience that the dynamically learned MAC address will remain associated to the switchport until the port security aging-time value expires. Moving the device to a different switch port should place the second switchport into a disabled mode (default) due to a port-security violation since the MAC address of the device is still associated to the original port. It has been sometime since I have experimented with this, but it should be a pretty easy thing to test quickly.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
