Overview

The maximum number of policies that you can attach to interfaces on an E-series

router depends on the classifier entries that make up the policy and the number of

attachment resources available on the interface. JUNOSe software allocates

interface attachment resources when you attach policies to interfaces. See Interface

Attachment Resources on page 118 for information about attachment resources.

An E-series router supports software and hardware classifiers. A policy can be made

up of any combination of software and hardware classifiers. You use the

classifier-list command to configure all classifiers.

There are two categories of hardware classifiers, depending on the type of line

module being used. OC48/STM16, GE-2, and GE-HDE line modules support

content-addressable memory (CAM) hardware classifiers—all other line modules

support FPGA hardware classifiers. Ta b l e 1 4 lists the classifiers supported on

OC48/STM16, GE-2, and GE-HDE line modules; Ta b l e 1 5 lists the classifiers

supported on all other line modules.
