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

17.3on page 120 for supported configurations and an example.
