D-Link Unified Switch CLI Command Reference
storm-control flowcontrol
This command enables 802.3x flow control for the switch and only applies to full-duplex mode ports.
Note: 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 can lead to high-priority and/or network control traffic
loss.
