Port Security
19.1 Port Security 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 163 ) to enable port security and disable MAC
address learning. You can also enable the port security feature on a port.
19.2 Port Security Setup
Click Advanced Application > Port Security in the navigation panel to display the screen as
shown.
