Product Descriptions

Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in the RSP7000 Flash memory, without having to remove and replace read-only memory (ROM) devices.

Note The RSP7000 uses a software-controlled conﬁguration register. There are no user-conﬁgurable jumpers on the RSP7000.

The RSP7000 contains the following components:

•Mips R4600 Reduced Instruction Set Computing (RISC) processor, used for the CPU (The CPU runs at an external clock speed of 50 MHz and an internal clock speed of 100 MHz.)

•A bank of hardware (Media Access Control [MAC]–layer) addresses for the interface ports

•Most of the memory components used by the system, including onboard Flash

•Air-temperature sensors for environmental monitoring (All of the logic for the environmental monitoring functions is contained on the chassis interface card.)

In addition to the system software, the RSP7000 contains and executes the following management functions that control the system:

•

Sending and receiving routing protocol updates

Managing tables and caches

Monitoring interface and environmental status

•Providing Simple Network Management Protocol (SNMP) management and the console/Telnet interface

The high-speed switching section of the RSP7000 communicates with and controls the interface processors on the high-speed CxBus. This switching section decides the destination of a packet and switches it accordingly. The RSP7000 uses a 16-million-instructions-per-second (mips) processor to provide high-speed, autonomous switching and routing.
