DEI based Classification on 7210 SAS-K
DEI based classification is supported on SAP ingress and access-uplink port ingress. DEI bit in the
received packet can be used to assign the ingress profile for the packet. If in the received packet,
DEI = 0, then the packet is considered to be GREEN or in-profile and if DEI = 1, then the packet is
considered to be YELLOW or out-of-profile. Use of DEI bit for ingress classification can be
enabled per FC. For a given FC, if DEI bit is used for ingress profile assignment, then the profile
defined in the ingress classification entry is ignored. For more information, see “Queue – Ingress
Profile Assignment on 7210 SAS-K on page 51” to understand the behavior when profile is
assigned to the packet on ingress.
