Port Security

16-1

This chapter shows you how to set up port security.

16.1 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. 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.
