DSCP marking CPU self-generated traffic

The user can configure DSCP marking for CPU-generated traffic on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C platforms only. See QoS for CPU self-generated traffic on network interfaces for the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C for more information about QoS for self-generated (CPU) traffic on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C. The following table lists the default DSCP and dot1p marking values for the 7210 SAS-K 2F1C2T.

Note:

Protocols such as BGP, RSVP, TLDP, OSPF, and IS-IS are not supported on 7210 SAS devices configured in access-uplink mode.
