Figure 123 Ethernet Port Configuration: Protocol VLAN Add
The following table describes the fields in this screen.
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.
To open the Port Security screen, right-click on the switch in the Device List Panel, and click
Configuration > Ethernet Port > Port Security. Then select a device and the port(s) to
which you want to apply this configuration.
