Mac Limit; Chapter 19 Mac Limit; Mac Limit Overview; Mac Limit: Port Security - ZyXEL Communications VES1724-56 User Manual

This chapter shows you how to set up port or vlan security by limiting learned MAC address(es).

19.1 MAC Limit Overview

MAC limit allows only packets with limited and dynamically learned MAC addresses and/or
configured static MAC addresses to pass through a port or a VLAN network on the switch. The
switch can learn up to 16K (16384 bytes) MAC addresses in total with no limit on individual ports.
For maximum port security, enable either port security or VLAN security, disable MAC address
learning and configure static MAC address(es) for a port or a VLAN. It is not recommended you
disable MAC Limit together with MAC address learning as this will result in many broadcasts.
