Quality of Service
(QoS) features
QoS features affect the way traffic is handled as it enters and exits the switch.
The following table describes the QoS features:
Flow-based mirroring Copy certain types of traffic to a single destination
port. You can configure the switch to mirror flows
based on Layer 2, Layer 3, and Layer 4 information.
Storm control Protect the network by detecting a traffic storm
(broadcast, multicast, or unknown unicast traffic
received at a very high rate) and preventing these
packets from flooding other parts of the network.
