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

Enhanced transmission selection
ETS provides customized bandwidth allocation to 802.1p classes of traffic. Assign different amounts of bandwidth to Ethernet, FCoE, or
iSCSI traffic classes 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 the required bandwidth, configure bandwidth and queue scheduling for each priority group. To prioritize low-latency storage
and server-cluster traffic, allocate more bandwidth to a priority group. To rate-limit best-effort LAN traffic, allocate less bandwidth to a
different priority group.
ETS configuration notes
ETS is supported on Layer2 (L2) 802.1p priority (dot1p 0 to 7) and Layer 3 (L3) DSCP (0 to 63) traffic. FCoE traffic uses dot1p priority
3 — iSCSI storage traffic uses dot1p priority 4.
