Port-security - quick one ;-)

Hey all. I'm stuggling to get me head around this. With port-security, if I
configure a static mac entry (switchport port-security mac-address
xxxx.xxxx.xxxx) then it is added to the running-config only - doesn't
survive a reboot. With 'sticky' port-security, the dynamically learned MAC
is added to the running config. However, this too will not survive a reboot.
Therefore, whats the difference?!?

With BOTH methods, you STILL NEED TO SAVE the RUNNING-CONFIG - or they are
lost (of course the sticky will get re-learned). The only difference I can
see between the two, is that:
Sticky automatically adds the MAC address to running-config
Static configuration requires manual entry of the MAC address to
running-config

Any thoughts/comments?

P.S. My lab is 21st Feb Brussells, anyone else out there that day?
