Table 20: Size Limit Of Combined Ip Classifiers - Juniper JUNOSE SOFTWARE FOR E SERIES 11.3.X - POLICY MANAGEMENT CONFIGURATION GUIDE 2010-10-04 Configuration Manual

Copyright © 2010, Juniper Networks, Inc.
Table 20 on page 157 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 157 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.

(Bits) Rule
8 When you specify one or both of the color and TCP
flags classifiers, 8 bits are added to the total classifier
entry size.
32 –
8 –
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.
8 –
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.
32 –
16 When you do not specify the source port and
destination port classifiers, but you specify one or more
of ICMP type, ICMP code, and IGMP type, 16 bits are
added to the total classifier entry size.
ICMP type, ICMP code, and IGMP type require 16 bits
even if the source port and destination port
classifications are not configured.
