(Optional) Specifies that the rule matches only packets with the specified

(Optional) Specifies that the rule matches only IPv6 packets whose Flow
Label header field has the value specified by the flow-label-value argument.
The flow-label-value argument can be an integer from 0 to 1048575.
(Optional) Specifies that the rule matches noninitial fragmented packets
only. The device considers noninitial fragmented packets to be packets with
a fragment extension header that contains a fragment offset that is not equal
to zero. You cannot specify this keyword in the same rule that you specify
Layer 4 options, such as a TCP port number, because the information that the
devices requires to evaluate those options is contained only in initial
fragments.
