ERX System Overview
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
