However,Dell Networking does recommend using Ingress traffic classification using the service-class dynamic dot1p command(honor dot1p) on all DCB-enabled interfaces. If you use L2 class maps to map dot1p priority traffic to egress queues, take intoaccount the default dot1p-queue assignments in the following table and the maximum number of two lossless queues supportedon a port (refer to Configuring Lossless Queues).Although Dell Networking OS allows you to change the default dot1p priority-queue assignments (refer to Setting dot1p Priorities forIncoming Traffic), DCB policies applied to an interface may become invalid if you reconfigure dot1p-queue mapping. If the configuredDCB policy remains valid, the change in the dot1p-queue assignment is allowed.NOTE: Although, each port on the S4810, S4820T, and S5000 devices support 8 QoS queues, you can configure only 4 QoSqueues (0-3) to manage data traffic. The remaining 4 queues (4-7) are reserved for control traffic.dot1p Value inthe IncomingFrameEgress Queue Assignment0 01 02 03 1288 Data Center Bridging (DCB)
