Administrator Guide

• Similarly, if you enable unicast storm control on an interface or globally on ingress, and DSCP marking
for a DSCP value 2 is configured for the data traffic, the traffic goes to queue 2 instead of queue 0.
NOTE: Bi-directional traffic (unknown unicast and broadcast) along with egress storm control
causes the configured traffic rates split between the involved ports. The percentage of traffic that
each port receives after the split is not predictable. These ports can be in the same/different port
pipes or the same/different line cards.
NOTE: The policy discard drop counters are common across storm-control drops, ACL drops and
QoS drops. Therefore, if your configuration includes ACL and QoS, those drops are also computed
and displayed in the policy discard drops counter field along with storm-control drops. The packets
dropped by the storm control feature can be monitored by viewing the value of the Policy Discard
Drops field of the output of the show hardware stack-unit 0 drops command.
