PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct
Internet connection if you do not have a router. PPPoE is a dial-up connection. You
need a username and password from your Internet Service Provider (ISP) to set
up the connection.
Jumbo Frames
Jumbo frames are Ethernet frames larger than 1500 bytes. They enable data
transfer with less overhead. The bigger the frame, the better the network
performance. Your network equipment such as computers, switches and routers
must be capable of supporting jumbo frames. You also need to enable jumbo
frames in all related network devices.
To use jumbo frames, your LAN must support 1 Gbps transmissions (Gigabit
Ethernet). All of your network devices (computer Ethernet cards and switches,
hubs, or routers) must also support the same size of jumbo frames that you
specify in the NSA.
Note: If you enable jumbo frames on the NSA in a network that does not support
them, you will lose access to the NSA. If this occurs, you will have to restore the
factory default configuration. Push the RESET button on the NSA's rear panel
and release it after you hear a beep.
