Table 20: Size Limit Of Combined Ip Classifiers - Juniper POLICY MANAGEMENT - CONFIGURATION GUIDE V11.1.X Configuration Manual

Table 19: Size Limit of Individual IP Classifiers (continued)

User packet class
Table 20 on page 165 lists the IP 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 20 on page 165 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.

16 The ICMP type, ICMP code, IGMP type, and destination
port classifiers share the same classifier field location.
When you specify the destination port classifier, 16
bits are added to the total classifier entry size. If you
also specify the ICMP type, ICMP code, and IGMP type
classifier, no additional bits are added.
8 When you specify one or more of the IP flags, traffic
class, and IP fragmentation classifiers, 8 bits are added
to the total classifier entry size.

16 The ICMP type, ICMP code, IGMP type, and source
port classifiers share the same classifier field location.
When you specify the source port classifier, 16 bits
are added to the total classifier entry size.
When you also specify the ICMP type, ICMP code, and
IGMP type classifiers, no additional bits are added.
