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 trac. Assign dierent amounts of bandwidth to Ethernet, FCoE, or
iSCSI trac classes that require dierent bandwidth, latency, and best-eort treatment during network congestion.
ETS divides trac into dierent priority groups using their 802.1p priority value. To ensure that each trac class is correctly prioritized and
receives the required bandwidth, congure bandwidth and queue scheduling for each priority group. To prioritize low-latency storage and
server-cluster trac, allocate more bandwidth to a priority group. To rate-limit best-eort LAN trac, allocate less bandwidth to a dierent
priority group.
