what's the difference between
a) switchport port-security mac-address xxxx.xxxx.xxxx
b) switchport port-security mac-address sticky xxxx.xxxx.xxxx
Somewhere deep down in the documentation I find that you may use both, but should prefer the version without sticky. Why ? Is there a difference ? At a first glance, I don't see any.
Maybe "sticky xxxx.xxxx.xxxx" in a config is just an indicator to give you a quick visual indication that this mapping was learned and written to the config dynamically - opposed to static mapping without "sticky"? If so, what sense is behind doing static mapping and still be able to use sticky in combination with static mac-addresses like in version b) above ?
