CHAPTER 17
Port Security
This chapter shows you how to set up port security.
17.1 Port Sercurity Overview
Port security allows only packets with dynamically learned MAC addresses and/or configured
static MAC addresses to pass through a port on the switch.
For maximum port security, enable this feature, disable MAC address learning and configure
static MAC address(es) for a port.
Functionally the switch allows for three possible outcomes with port security. You can
configure the ports to:
Forward all packets and learn all MAC addresses.
Drop all packets from unknown MAC addresses and do not learn MAC addresses.
Drop all packets from unknown MAC addresses and learn a limited number of MAC
addresses.
Note: The switch supports five possible configurations for port security. See Section
17.3 on page 120 for supported configurations and an example.
17.2 Port Security Setup
Click Advanced Application, Port Security in the navigation panel to display the screen as
shown.
