1. Portsecurity
Portsecurity is a feature that can limit the MAC adresses that are allowed on a physical
port. A violation of the port security occurs if
-
the number if MAC adresses on a port is reached an the MAC id is different from the allowed list
-
an allowed MAC id is connected to a differnt port in the same VLAN
Port security is seen as a deterrent for people that want to connect rogue devices
to your network.
