I have a large network with vlan, dtp, trunk, etc. Sniffing traffic on some switch, i found unicast traffic flooded on all ports. I know how catalyst switch work, and there was 2 situation on which this happen
1)Mac address table full
2)Mac address of destination not in list
Ok. But i would like to know if there is a method to avoid this situations.
Can you give me some link that point out this kind of problems?
