Software Classifiers Overview
An E Series router supports a variety of software classifiers, depending on the type
of interface. Table 17 on page 160 and Table 18 on page 161 list the supported software
classifiers for each interface type.
A line module supports 16,383 software classifiers. Software classifiers are consumed
at a rate of one resource per classifier category per policy. For example, if you
configure a policy that has three different destination route class rules, then because
all three rules are for the same classifier category, that policy consumes only one
software classifier resource. However, if you configure a policy that requires
classification on three different classifier categories, such as ToS, color, and TCP
flags, then that policy consumes three of the available 16,383 software classifier
resources.
NOTE: Policy consumption is per policy definition per line module.
In this example, the policy list named polWestford5 references four classifier lists
with a combination of software and hardware classifiers.
