This chapter shows you how to set up port security.
19.1 Abo ut Po rt Se c urity
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
addresses 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.
