Configure Switch Port Security

26.7k

There are three types of switch ports Access ports, Trunk ports and Voice ports.

Port security is the process of securing ports and preventing unauthorized access. This can be done through a number of ways, such as:

  • Heightened surveillance in and around the port
  • Physical barriers in and around the port
  • Detecting and identifying unauthorized persons in and around the port
  • Detaining unauthorized persons in and around the port

Three steps are necessary to configure port security:

  • Use the switchport mode access interface subcommand to make the interface an access interface.
  • Use the switchport port-security interface subcommand to enable port security.
  • Use the switchport port-security mac-address MAC ADDRESS interface subcommand to
  • specify which MAC addresses are allowed to send frames through this interface, or use the swichport port-security mac-address sticky interface subcommand to dynamically learn the MAC address of the currently connected host.

The primary goal of port security in a switch is to prevent unauthorised users from gaining access to the LAN.

On Cisco equipment there are three different main violation types: shutdown, protect, and restrict.
