CHAPTER 19
Port Security
This chapter shows you how to set up port security.
19.1 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 32K MAC addresses in total with no limit on individual ports other
than the sum cannot exceed 32K.
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.
