Port Security

This chapter shows you how to set up port security.

17.1 About 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. See

Appendix A on page 305

for

the maximum number of MAC addresses the Switch can learn. There is no other limit on the
maximum number of MAC addresses per port the Switch can learn, as long as the number of
MAC addresses does not exceed the value in

Appendix A on page 305

.

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.

17.2 Port Security Setup

Click Advanced Application > Port Security in the navigation panel to display the screen as
