Configuring Port Settings
By default, the appliance automatically detects the Ethernet port's link speed and duplex. If
desired, you can manually restrict the Ethernet port to a specific link speed and duplex.
You can also configure appliance to use jumbo frames. While the standard Ethernet frame is
1500 bytes, jumbo frames are larger, with the conventional jumbo frame size being 9000
bytes.
