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 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.
