The following are configuration guidelines for DEI-based classification and marking:
While disabling DEI-based classification on a port, all the meters used by the SAPs configured on this port must be in color-blind mode. The converse is also true, that is, while attaching a SAP-ingress QoS policy with meter as color aware to a SAP, the DEI-based classification must be enabled on the port where the SAP exists.
While configuring DEI-based classification in a access-uplink network QoS Policy (ingress), only dot1p classification can be used.
DEI classification must be disabled on that port before changing the mode (access, access-uplink, network, hybrid) to another mode.
All the ports under a LAG should have the same configuration for DEI classification (either enabled or disabled for all member ports of a LAG). If the LAG configuration changes, the port configuration is also updated accordingly. Port configuration under the LAG cannot be changed.
