Line Modules
Line modules process data from different types of network connections.
For information about the available line modules and which SRP
modules support specific line modules, see
Appendix B, Module
Specifications .
Figure 1-9 shows a representative line module. For details about installing
line modules, see Chapter 3, Installing ERX Modules .
Packet Classification
Each line module supports packet classification on ingress. 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.
