Packet Classification

Most line modules support packet classification on ingress; some non-ASIC line modules
do not. A classification engine on the line module matches specific fields (such as source
and destination IP address, source and destination port, and protocol), the ingress IP
interface, layer 2 fields, or some combination of these against user-configured filters at
wire speed.
Most line modules have a corresponding input/output (I/O) module that provides the
physical interconnection to the network. Insert each I/O module into the back of the
system, directly behind its corresponding line module.
For information about which line modules pair with which I/O modules, see the ERX
Module Guide. See Figure 2 on page 5, Figure 4 on page 7, and Figure 6 on page 8 for
locations. For details about installing I/O modules, see "Installing Modules" on page 31.
You can use different management tools to configure the system to meet the specific
networking requirements.
