16.11 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.
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.
Follow the steps below to configure the Port Security screen.
1 In the Device Panel list, select a device and then right-click.
2 Click Configuration > Ethernet Port Configuration > Port Security.
3 Select a device and the port(s) to which you want to apply this configuration.
