Enhanced transmission selection
Enhanced transmission selection (ETS) provides customized bandwidth allocation to 802.1p classes of trac. Assign dierent amounts of
bandwidth to trac classes (Ethernet, FCoE, or iSCSI) that require dierent bandwidth, latency, and best-eort treatment during network
congestion.
ETS divides trac into dierent priority groups using their 802.1p priority value. To ensure that each trac class is correctly prioritized and
receives required bandwidth, congure 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 trac. Allocate less bandwidth to a dierent priority group to rate-limit
best-eort LAN trac.
