13.9 Port Security

13.9.1 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.

13.9.2 Configuring Port Security
