Usage
Information
Use the details option to display PFC statistics on received/transmitted frames for each dot1p (CoS)
value, and use the clear qos statistics interface ethernet 1/1/1 command to delete
PFC statistics and restart the counter.

Enhanced transmission selection
Enhanced transmission selection (ETS) provides customized bandwidth allocation to 802.1p classes of traffic. Assign different
amounts of bandwidth to traffic classes (Ethernet, FCoE, or iSCSI) that require different bandwidth, latency, and best-effort
treatment during network congestion.
ETS divides traffic into different priority groups using their 802.1p priority value. To ensure that each traffic class is correctly
prioritized and receives required bandwidth, configure bandwidth and queue scheduling for each priority group. You can allocate
more bandwidth to a priority group to prioritize low-latency storage and server-cluster traffic. Allocate less bandwidth to a
different priority group to rate-limit best-effort LAN traffic.
