Jumbo Frames Jumbo frames improve network performance. You must have a 1 Gbps (Gigabit
Ethernet) network that supports jumbo frames. Select the largest size of frame
that all of your network devices (including computer Ethernet cards and switches,
hubs, or routers) support.
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.
Network
Diagnostic Tool
Use this section to test the network connection to a particular IP address or
domain name. Select an address or type it into the field. Then click Ping to have
the NSA send a packet to test the network connection. If the NSA is able to “ping”
the host, the network connection is OK.
Apply Click Apply to save your TCP/IP configurations. After you click Apply, the NSA
restarts. Wait until you see the Login screen or until the NSA fully boots and then
use the NDU to rediscover it.
Reset Click Reset to begin configuring this screen afresh.
