This chapter describes the control plane of the ME60-X16.
2.5.1 Introduction to the Control Plane
This section describes the functions of the control plane.
The control plane of the ME60-X16 is separated from the data plane and the monitoring plane.
The MPU on the ME60-X16 is responsible for system control and management, including route
calculation, device management and maintenance, and device monitoring.

Description
Before the registration of the SFU: If the indicator blinks twice every second (2
Hz), the system is in the alarm state.
After the registration of the SFU: If the indicator blinks once every two seconds
(0.5 Hz), the system is running normally.
If the indicator is on, it indicates that the SFU is working normally; if the green
indicator is off, it indicates that the SFU is faulty.
When the SFU is working normally, the OFL indicator is off. After the OFL
button is pressed to power off the SFU, the OFL indicator is on.
NOTE
Route calculation: All routing protocol packets are sent by the forwarding engine to the
MPU for processing. In addition, the MPU broadcasts and filters packets, and downloads
routing policies from the policy server.
Outband communication between boards: The LAN switch modules integrated on the MPU
provide outband communications between boards. In this manner, messages can be
controlled, maintained, and exchanged between SFUs and LPUs.
Device management and maintenance: Devices can be managed and maintained through
the management interfaces (serial interfaces) provided by the MPU.
Data configuration: The MPU stores configuration data, startup files, charging information,
upgrade software, and system logs.
