CHAPTER 22 Port Security 22.1 Port Security Use this screen to allow only packets with dynamically learned MAC addresses and/or configured static MAC addresses to pass through a port on the switch. See Chapter 48 on page 269 for the maximum number of MAC addresses the switch can learn. For maximum security, enable port security, 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. To open this screen, click Advanced Application > Port Security. Figure 47 Port Security The following table describes the labels in this screen. Table 38 Port Security LABEL DESCRIPTION Active Select this option to enable port security on the switch.
