SRP Module
Switch route processor (SRP) modules perform system management,
routing table calculations and maintenance, forwarding table
computations, statistics processing, configuration storage, and other
control plane functions. Each SRP module is a PowerPC-based system
with its own memory, nonvolatile disk storage, and power supply (see
Figure 1-12 and Figure 1-13 ).
