The DEI bit in the received packet can be used to assign the ingress profile for the packet. If DEI equals zero in the received packet, the packet is considered in-profile or green and if DEI equals one, the packet is considered out-of-profile or yellow. The use of the DEI bit for ingress classification can be enabled per FC. For a specific FC, if the DEI bit is used for the ingress profile assignment, the profile defined in the ingress classification entry is ignored. See Ingress profile assignment for information about the behavior when a profile is assigned to the packet on ingress.

On the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C, DEI-based classification is supported on access SAP ingress, network port ingress, hybrid port ingress, and access-uplink port ingress.
