Description
Enable or disable IEEE 802.3x flow control by selecting the
corresponding line on the menu. Flow control helps to prevent data loss
when the port cannot keep up with the number of frames being
switched. When enabled, the switch can send a PAUSE frame to stop
traffic on a port if the amount of memory used by packets on the port
exceeds a preconfigured threshold and responds to pause requests
from partner devices. The paused port does not forward packets for the
period of time specified in the PAUSE frame. When the PAUSE frame
time elapses or the utilization returns to a specified low threshold, the
switch enables the port to again transmit frames. The factory default is
disabled. For LAG interfaces Flow Control mode is displayed blank, as
flow control is not applicable.
Enable or disable this option by selecting the corresponding line on the
entry field. When you specify Enable for broadcast storm recovery and
the broadcast traffic on the specified Ethernet port exceeds the
configured threshold, the switch blocks (discards) the broadcast traffic.
The factory default is enable.

Enable or disable this option by selecting the corresponding line on the
entry field. When you specify Enable for unicast storm recovery and the
unicast traffic on the specified Ethernet port exceeds the configured
threshold, the switch blocks (discards) the unicast traffic. The factory
