Using ETS, you can create groups within an 802.1p priority class to configure differenttreatment for traffic with different bandwidth, latency, and best-effort needs.For example, storage traffic is sensitive to frame loss; interprocess communication (IPC) traffic is latency-sensitive. ETS allows differenttraffic types to coexist without interruption in the same converged link by:• Allocating a guaranteed share of bandwidth to each priority group.• Allowing each group to exceed its minimum guaranteed bandwidth if another group is not fully using its allotted bandwidth.ETS Prerequisites and RestrictionsThe following prerequisites and restrictions apply when you configure ETS bandwidth allocation or queue scheduling.• Configuring ETS bandwidth allocation or a queue scheduler for dot1p priorities in a priority group is applicable if the DCBx version usedon a port is CIN (refer to Configuring DCBx).• When allocating bandwidth or configuring a queue scheduler for dot1p priorities in a priority group on a DCBx CIN interface, take intoaccount the CIN bandwidth allocation (refer to Configuring Bandwidth Allocation for DCBx CIN) and dot1p-queue mapping.NOTE: The IEEE 802.1Qaz, CEE, and CIN versions of ETS are supported.Creating an ETS Priority GroupAn ETS priority group specifies the range of 802.1p priority traffic to which a QoS output policy with ETS settings is applied on an egressinterface.1 Configure a DCB Map.CONFIGURATION mode266 Data Center Bridging (DCB)
