Functions

The LX1D2MFUXC00 integrates the control and switching functions and provides the control plane, management plane, and data plane for the system.

The control plane provides functions such as protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics collection, and system security.
The management plane is responsible for system status monitoring, environment monitoring, log and alarm processing, system software loading, and system upgrades.
The data plane provides high-speed, non-blocking data channels for data switching between service modules.

The LX1D2MFUXC00 consists of the following functional modules:

Control module: functions as the control plane and management plane for the LX1D2MFUXC00 and the entire system, implementing protocol processing, route calculation, forwarding control, system management, and system security.
Switching module: functions as the data plane and provides high-speed service channels for data switching.
Local clock module: provides the working clock for the chips of the control module, switching module, and equipment management and monitoring module on the LX1D2MFUXC00.
Device management and monitoring module: provides functions of a controller area network (CAN) bus module to monitor the LX1D2MFUXC00 and manage the CAN bus modules of LPUs.
Power supply module: provides power supply for the LX1D2MFUXC00.

Table 7-5 Functions of the LX1D2MFUXC00

Function	Description
Basic function	Core of control and management for the S9310X system, and integrates the main control unit, clock unit, switching unit, and system maintenance unit.
Distributed forwarding	Uses a distributed data plane to forward data concurrently.
Memory	4 GB
eUSB card	2 GB The system configuration data, startup files, system software package, and system logs are saved in the eUSB card by default.
Clustering	Provides 10GE and 40GE optical ports for cluster connection.
Clock	Provides stratum-3 clock, synchronous Ethernet, and IEEE 1588v2 functions when equipped with an LE0D00CKMA00 clock daughter card.
Redundancy backup	Supported MPUs are mandatory for switches. You can configure one or two MPUs for each switch. The MPU can be installed in either MPU slot of a switch. An MPU consists of the control plane, management plane, and data forwarding plane. When two MPUs are installed, the two MPUs work in hot standby mode on the control and management planes and work in load balancing mode on the data forwarding plane. MPUs monitor each other. When the active MPU is faulty, the standby MPU is automatically switched to be the active MPU to ensure service continuity.
Hot swapping	Supported Before removing the active LX1D2MFUXC00, perform an active/standby switchover.

Usage Constraints

Main control units of different models cannot be used in the same chassis.
The fans in a switch work in intelligent speed adjustment mode after a switchover between the active and standby main control units in the switch. If the fans run at a specified speed before a switchover, run the set fan-speed command after the switchover to set the fan speed again.

Each LX1D2MFUXC00 main control unit has two port groups: group 1 with 10GE ports 1-4 and group 2 with 40GE port 1. Two chassis can set up a cluster only when the following requirements are met:

One main control unit can only be connected to one main control unit card in the other chassis. It cannot be connected to more than one main control unit in the other chassis or the other main control unit in the local chassis.
Ports in group 1 on one main control unit can only be connected to ports in group 1 on the other main control unit. These ports must be connected sequentially based on their numbers. The port in group 2 on one main control unit can only be connected to the port in group 2 on the other main control unit.
The two chassis must be connected by at least one cluster cable.

To keep cluster cables neat and facilitate maintenance, you are advised to connect the two chassis according to Figure 7-6 or Figure 7-7:

Connect at least two cables on each main control unit.
Install two main control units in each chassis.
