Service groups are the most general taxonomy of traffic management types. Different service types and categories belong to each one of the service groups.

Table A-1. VSI Service Groups
Service Group	Description
0	MPLS service categories
1	ATM Forum service categories
2	IP service categories (obsolete)
3 through 10	Vendor-specific service categories (used by local agreement between switch and controller)

NOTE

The IP service group (2) and its corresponding service types and service categories are obsolete, because DiffServ has redefined the meaning of the Type of Service (ToS) bits of the IP packet header.
