docs Mcast Cmts Group Cfg Tos Low

This attribute identifies the low value of a range of the TOS byte value to be defined in a packet classifier this GC instantiates in the GCR in order to limit the GCR-matched traffic to a particular set of DSCPs. This applies to the IPv4 TOS byte and the IPv6 Traffic Class byte. The IP TOS octet, as originally defined in RFC 791, has been superseded by the 6-bit Differentiated Services Field and the 2-bit Explicit Congestion Notification Field.
