Tip 
Less aging time  will drive the dynamic  MAC address table to  refresh 
more  frequently  and  destination  addresses  in  the  received  data 
packages cannot be found. As a result, the switch is only capable of 
broadcasting these Packages to all ports, at the price of damaging the 
switch performance. 
Much aging time will force the dynamic MAC address table to save up 
more stale addresses until it uses up all address tables. Eventually, the 
switch fails to refresh them upon changing network.
