description in "Match Attributes (IPv4)" on page 627. Click the check box for each field to be used as a
criterion for a class, and enter data in the related field. You can have multiple match criteria in a class.
The logic is a Boolean “logical-and” for this criteria.

IPv6 Flow Label
— Flow label is a 20-bit number that is unique to an IPv6 packet, used by end
stations to signify quality-of-service handling in routers. The flow label of the incoming packet must
match this value. Range is 0-1048575.
Service Type Criteria
