First, why is there a sticky security MAC address? The reason is that although the static security MAC address can make an interface of the switch to allow only a fixed computer access, but need to do is to find the MAC address of the computer, so, at this time with a sticky

Microsoft recently said it would fix Windows security vulnerabilities to reduce new network-based security risks. However, security researchers said Linux/Mac OS Operating systems may have the same security risks. Nathan McFeters, one of the

time, the cam table of the switch is filled up and no new entries can be accepted. The behavior of the attack needs to persist, otherwise the MAC address will be emptied of the cam table after aging.3. The switch starts to flood all the packets it receives to all the ports. As a result, an attacker could get all the packets in the network on any port.Defensive measuresQualify a specific MAC address or limi
