Figure 4-7 Diagram of main control card

The control module is composed of the main processor and some external application
chips. It provides external operation interfaces, for example, serial ports and Ethernet
ports, by which the system can process all kinds of applications. The main processor is a
high-performance CPU processor, which performs the following functions:

System NM protocol, for example, SNMP

Network protocols, for example, OSPF, RIP, and BGP-4

Providing the operation and management interfaces for line cards

Data operation and maintenance
The switch module is designed with a dedicated Switch chip, which is integrated with
multiple Gigabit and Gigabit bi-directional interfaces, allowing it to process wire-speed
switching of multiple ports. The Switch chip provides the following functions:
1. Store and forward switching
2. Supporting 9KB jumbo frames
