This section describes how this feature works.
DSCP Marking IEs
DSCP marking IEs are sent in the Sx Establishment Request or the Sx Modification Request message. These IEs are a part of Forwarding Action Rule (FAR) IE. The following are the supported IEs and their functions:
-
Inner Packet Marking (Private Extension IE): Sends the user-datagram DSCP marking values to the UP.
-
Transport Packet Marking (3GPP Spec-defined IE): Sends the encaps-header DSCP values to the UP.
-
Transport Packet Marking Options (Private Extension IE): Sends copy-inner and copy-outer options of encaps-header marking to the UP.
