storm-control unicast all level
This command configures the unicast storm recovery threshold in terms of percentage of the
interface speed for an interface, and enables unicast storm recovery for all interfaces. If the
mode is enabled, unicast storm recovery is active, and if the rate of unknown L2 unicast
(destination lookup failure) traffic ingressing on an interface increases beyond the configured
threshold, the traffic will be dropped. Therefore, the rate of unknown unicast traffic will be
limited to the configured threshold.
no storm-control unicast all level
This command returns the unicast storm recovery threshold to the default value and disables
unicast storm recovery for all interfaces.
storm-control flowcontrol
This command enables 802.3x flow control for the switch and only applies to full-duplex mode
ports.
no storm-control flowcontrol
This command disables 802.3x flow control for the switch.

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.
