Chapter 5: Configuring the Switch through the Web Utility
System Information
24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet
System Mode
The System Mode screen displays the following information.
Jumbo Frames. Shows if jumbo frames are enabled.
This switch provides more efficient throughput for large sequential data transfers by supporting jumbo frames up
to 9216 bytes. Compared to standard Ethernet frames that run only up to 1.5 KB, using jumbo frames significantly
reduces the per-packet overhead required to process protocol encapsulation fields.
To use jumbo frames, both the source and destination end nodes (such as a computer or server) must support
this feature. Also, when the connection is operating at full duplex, all switches in the network between the two
end nodes must be able to accept the extended frame size. And for half-duplex connections, all devices in the
collision domain would need to support jumbo frames.
Enabling jumbo frames will limit the maximum threshold for broadcast storm control to 64 packets per second.
The current setting for jumbo frames can be displayed with the show system command.
Use the drop-down menu to Enable or Disable the transmitting and receiving of Jumbo Frames for this switch.
