I do some practice with switchport security.I activated sticky security on swich ports and did
violation-shutdown. The problem is now that i can not find how to acitvate them again without
reseting my switch. The command "no shutdown" in interface for, lets say, fa0/1 just simple do
nothing.  After violation i tried to do: "interface fa0/1 shut" and then "no shut" - it tries
to activate but after couple of seconds it shows violation again. How to switch off the
"violation" ?

Many thanks
