SRP Modules Bandwidth
Different SRP modules offer different bandwidths:
■ The SRP-10G module provides 2.5 Gbps bandwidth per slot group.
■ The SRP-5G+ module (ERX705 router only) provides:
■ 2.5 Gbps bandwidth per slot group
■ 5 Gbps bandwidth per router
Line Modules Bandwidth and Switch Usage
The SRP-5G+ and SRP-10G modules comprise two switches; each switch provides
50 percent of the bandwidth.
The line modules in a slot group cannot operate at line rate if:
■ The sum of their bandwidths exceeds the bandwidth that the SRP module can
supply per slot group.
■ The sum of the bandwidths they require from one SRP switch exceeds the
bandwidth that the SRP switch can supply per slot group.
Table 40 on page 374 shows the bandwidth that each line module requires for line
rate performance and the switches that the line module can use on the SRP-5G+
and SRP-10G modules.
