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.
19.1.1 Wha t Yo u C a n Do
Use the
Po rt Se c urity
screen ( Section 19.2 on page 180 ) to enable port security and disable MAC
address learning. You can also enable the port security feature on a port.
