Table 22 on page 167 lists the IPv6 classifiers that share the same classifier entry
location and those that are combined to form a larger classifier field. The table also
lists the rules that apply to these types of classifier combinations.
The format in the classifier entry combinations in Table 22 on page 167 is based on
the conventions for CLI commands, except that the pipe symbol ( | ) represents a
choice of one or both options to the left and right of the pipe symbol.

When you specify the color and/or TCP flags
classifiers, 8 bits are added to the total classifier

When you specify the destination port
classifier, 16 bits are added to the total
classifier entry size. If you also specify the
ICMPv6 type and ICMPv6 code classifiers, no
additional bits are added to the total classifier
entry size.

When you do not specify the source port and
destination port classifiers, and you have
already specified one or more of the ICMPv6
Type and ICMPv6 code classifiers, 16 bits are
added to the total classifier entry size.
The ICMPv6 type and ICMPv6 code classifiers
require 16 bits even if you have not specified
the source port and destination port classifiers.
