Cisco Systems Cisco 12008 manual Performance Route Processor

Overview of the Cisco 12008

Note The RJ-45 and MII receptacles on the GRP faceplate represent two physical connection options for one Ethernet interface; therefore, you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously.

Performance Route Processor

Each Cisco 12012 GSR has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards. The RP also performs general maintenance functions, such as diagnostics, console support, and line card monitoring.

Two types of RPs are available for the Cisco 12012 GSR:

•

•

Gigabit Route Processor (GRP)

Performance Route Processor (PRP)

When not explicitly specified, this document uses the term route processor (RP) to indicate either the GRP or the PRP.

Note If you install a second, redundant RP, it must be of the same type as the primary RP.

The section describes the Performance Route Processor (PRP) and includes the following information:
