Configuring Port Security

Configuring Port Security

The port security function changes MAC addresses learned on an interface into secure MAC addresses (including secure dynamic MAC addresses and sticky MAC addresses). Only hosts using secure MAC addresses or static MAC addresses can communicate with the device through the interface. This function enhances security of the device.

Pre-configuration Tasks

Before configuring port security on an interface, complete the following tasks:

  • Disable MAC address limiting on the interface.
  • Disable MUX VLAN on the interface.
  • Disable MAC address security for DHCP snooping on the interface.
