Netgear GS728TPP – 28PT GE POE+ SMART SWITCH Guia Do Administrador

The screens you access from the Ports menu allow you to view and monitor the physical port 
information for the ports available on the switch. From the Ports menu, you can access the 
features described in the following sections:

IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed 
and dropping all traffic for small bursts of time during the congestion condition. This action 
can lead to high-priority and network control traffic loss. When IEEE 802.3x flow control is 
enabled, lower-speed switches can communicate with higher-speed switches by requesting 
that the higher-speed switch refrains from sending packets. Transmissions are temporarily 
halted to prevent buffer overflows.

Jumbo frames support packets of up to 9 Kilobytes in size. If jumbo frames are not enabled 
(default), the system supports packet size up to 2048 bytes. For jumbo frames to take effect, 
the switch must be rebooted after the feature is enabled.
