Global Configuration

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 1,518 bytes. For jumbo frames to take effect, the switch must be rebooted after the feature is enabled.
