IPv6 Class Configuration
The IPv6 Class Configuration feature extends the existing DiffServ functionality by providing
support for IPv6 packet classification. An Ethernet IPv6 packet is distinguished from an IPv4
packet by its unique EtherType value, so all IPv6 classifiers include the EtherType field.
Packets that match an IPv6 classifier are only allowed to be marked using the 802.1p (COS)
field or the IP DSCP field in the Traffic Class octet. IP Precedence is not defined for IPv6: this
is not an appropriate type of packet marking.
