3.9 Control Plane

This chapter describes the control plane of the E8000E-X8.

3.9.1 Introduction to the Control Plane

This section describes the functions of the control plane.
E8000E-X8 uses the SRUA and CMU to implement the functions of the control plane. The
functions are described as follows:
System Control and Management Unit
As the system control and management unit, the SRUA provides the following functions on the
system control panel:

System Maintenance Unit
As the system maintenance unit, the SRUA collects system monitoring information to test system
units locally or remotely, or implement in-service upgrading of system units.
The SRUA periodically collects information about the operation of system units through the
Monitorbus. The SRUA then generates related control information based on the collected
information, for example, the detection of board installations and adjustments to fan speed.
Through the joint test action group (JTAG) bus, the SRUA remotely or locally tests system units,
or performs in-service upgrading of system units.

Route calculation: All routing protocol packets are sent by the forwarding engine to the
SRUA for processing. In addition, the SRUA broadcasts and filters packets, and downloads
routing policies from the policy server.
Outband communication between boards: The LAN switch modules integrated on the
SRUA provide outband communications between boards. In this manner, messages can be
controlled, maintained, and exchanged between the boards.
Device management and maintenance: Devices can be managed and maintained through
the management interfaces (serial interfaces) provided by the SRUA.
Data configuration: The SRUA stores configuration data, startup files, charging
information, upgrade software, and system logs.
Data storage: The SRUA provides two interfaces for CF cards, which serve as mass storage
devices to store data files.
