CHAPTER 19

Port Security

19.1 Overview

This chapter shows you how to set up port security.

Port security allows only packets with dynamically learned MAC addresses and/or configured static

MAC addresses to pass through a port on the Switch. The Switch can learn up to 16K MAC

addresses in total with no limit on individual ports other than the sum cannot exceed 16K.

For maximum port security, enable this feature, disable MAC address learning and configure static

MAC address(es) for a port. It is not recommended you disable port security together with MAC

address learning as this will result in many broadcasts. By default, MAC address learning is still

enabled even though the port security is not activated.

19.1.1 What You Can Do

Use the Port Security screen (Section 19.2 on page 152) to enable port security and disable MAC

address learning. You can also enable the port security feature on a port.
