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.
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.
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.
In the following example, the NSA has jumbo frames enabled and set to 8KB frames. This means
the computer, notebook computer, and switch must also have jumbo frames enabled and be
capable of supporting 8KB frames.
