Figure 29 MAC Table Flowchart
7.4 Static MAC Settings
A static Media Access Control (MAC) address is an address that has been manually
entered in the MAC address table. Static MAC addresses do not age out. When you
set up static MAC address rules, you are setting static MAC addresses for a port.
This may reduce the need for broadcasting.
Click Basic Settings > MAC Management > Static MAC Settings in the
