This chapter shows you how to set up 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. By default, MAC address learning is still enabled even though the port

security is not activated.
