Port Security of Access Layer Switches
Port Security is a layer 2 access control feature that allows network administrators to control which devices can connect to a specific switch port. It does this by restricting the MAC addresses allowed on that port and defining how the switch reacts to unauthorized devices. Let's consider the following example. Imagine an open office space with desks everywhere. What stops someone with access to the office from unplugging a device at an empty desk and plugging their rogue device into the wall jack, as shown in the diagram?Catalyst Integrated Security Features (CISF) includes private VLANs, port security, DHCP snooping, IPSource Guard, secure Address Resolution Protocol (ARP) detection, and dynamic ARP inspection.
