For details about installing the SRP I/O module, see "Installing Modules" on page 31.

Line Modules

Line modules (LM) process data from different types of network connections. For
information about available line modules and which SRP modules support specific
line modules, see the ERX Module Guide.
Figure 11 on page 13 shows a representative line module. For details about installing
line modules, see "Installing Modules" on page 31.

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.
BNC connectors and wire wraps are available for ERX7xx and ERX14xx models
only.
