A maximum of four observing ports can be configured on an Huawei S3700. Packets from
multiple ports can be mirrored to the same observing port. You can mirror incoming
packets, outgoing packets, or both to an observing port.

The S3700 supports Remote Switched Port Analyzer (RSPAN). That is, the observing
port and mirrored port can be located on different switches. This facilitates remote
device management.

The S3700 like S3700-28TP-EI-AC supports traffic mirroring. A maximum of four observing ports can be configured on an S3700. Flows can be mirrored from multiple ports to the same
observing port. Flows to be mirrored are determined by the traffic classification rule.

Huawei OSN 8800 System Architecture

Huawei OptiX OSN 8800 system uses the L0 + L1 + L2 architecture. Ethernet/MPLS-TP switching is implemented on Layer 2, ODUk/VC switching on Layer 1, and wavelength switching on Layer 0.

Figure 1 and Figure 2 show the system architecture of Huawei OptiX OSN 8800 used as an MS-OTN and an OCS system, respectively.

Figure 1 System architecture of the OptiX OSN 8800 (MS-OTN) 

 NOTE:

In Figure 1, L2 switching module is marked in a dotted line box, indicating that not all the OTU or tributary boards provide a Layer 2 switching module.

• An OTU board equipped with a Layer 2 switching module is referred to as an Ethernet over WDM (EoW) board, such as an LEM24 or LEX4 board.
• A tributary board equipped with a Layer 2 switching module is referred to as an Ethernet over OTN (EoO) board, such as a TEM28 board.

Figure 2 System architecture of the OptiX OSN 8800 (OCS) 

 NOTE:

An board equipped with a L2 switching module is referred to as an Ethernet over SDH (EoS) board in Figure 2. such as an EGSH or EAS2 board.

Functions of modules are as follows:

• Optical-layer boards are classified into optical multiplexer and demultiplexer boards, optical add/drop multiplexing (OADM) boards, optical amplifier (OA) boards, optical supervisory channel (OSC) boards, optical spectrum analysis boards, optical variable attenuator boards, and optical power and dispersion equalization boards. These boards are intended to process optical-layer services, for example, to cross-connect wavelengths at the optical layer.
• Electrical-layer boards such as OTU, tributary, and line boards are used to process electrical-layer signals, and perform conversion between optical and electrical signals. The OptiX OSN 8800 uses a tributary-line-separate architecture, and a centralized Huawei cross-connect unit to flexibly groom electrical-layer signals at different granularities.
• For OptiX OSN 8800, an universal line board is used to process electrical-layer signals and perform conversion between optical and electrical signals. In addition, an universal line board can work with a centralized cross-connect board to achieve hybrid transmission and fine-grained grooming of OTN, SDH, and packet services.
• For OptiX OSN 8800, EoO, EoW, Ethernet over SDH (EoS), and packet boards have L2 processing capabilities. They can add, strip, and exchange MPLS or VLAN tags, learn MAC addresses, and forward packets. Only packet boards can add, strip, or exchange MPLS tags.
• As the control center of the entire system, the system control and communication (SCC) board TN52SCC cooperates with the network management system (NMS) to manage boards in the system and to implement inter-subrack communication.
• The clock board provides system clock signals and frame header signals to each service board, and synchronizes the local system time with the upstream system time, achieving clock and time synchronization.
• The power supply and fan systems with a redundancy protection design ensure highly-reliable equipment operation.
• The auxiliary interface board provides functional ports such as clock/time input/output ports, management serial port, alarm output and cascading ports, and alarm input/output ports.
• Inter-board communication and service cross-connections, clock synchronization, and power supplies are implemented using the backplane buses. Backplane buses include control and communication buses, clock buses, and power buses.

Introduction of CES Services on Huawei Optix OSN equipment

The circuit emulation service (CES) helps to solve the problem of insufficient optical fiber resources in the access ring and allows TDM services to be transparently transmitted across the pure packet mode.

At the physical layer on the UNI side, Huawei OptiX OSN equipment is interconnected with a CE through the following physical channels for accessing CES services:

• Channelized STM-1
• E1

Figure 1 Networking diagram of the CES 

As shown in Figure 1, the OptiX OSN equipment can gain access to CES services at emulation node 1, emulation node 2, or emulation node 3.

• At emulation node 1, the OptiX OSN 1500 transmits E1 services to the GE packet ring.
• At emulation node 2, the OptiX OSN 3500, OptiX OSN 7500 or OptiX OSN 7500 II transmits E1 signals that are received from the BTS through TDM STM-1/STM-4 ring to the 10GE packet ring.
• At emulation node 3, the OptiX OSN 3500, OptiX OSN 7500 or OptiX OSN 7500 II converts E1 CESs on the 10GE packet ring into STM-1 signals and then sends them to the BSC.

The OptiX OSN equipment supports both structure-aware TDM circuit emulation service over packet switched network (CESoPSN) and structure-agnostic TDM over packet (SAToP). Installation guide like OSN 3500 configuration guide can be found in the Hedex files.

In the case of CESoPSN, the features are as follows:

• The equipment is aware of frame structures, frame alignment modes, and timeslots in TDM circuits.
• The equipment processes the overheads in and extracts the payloads from the TDM frames. Then, the equipment loads timeslots to the packet payload in a specific sequence. As a result, the services in each timeslot are fixed and visible in packets.

In the case of SAToP, the features are as follows:

• The equipment is agnostic about the structures of the TDM signals. To be specific, the equipment treats TDM signals as constant bit-rate (CBR) flows, and emulates all the TDM signals in the same way.
• The overheads and payloads in TDM signals are transparently transmitted.

Huawei optical transponder board LSX Application

As a type of optical transponder unit, Huawei LSX board maps one channel of 10 Gbit/s service signals into OTU2 or OTU2e signals and performs conversion between the 10 Gbit/s service signal and WDM signals that comply with ITU-T Recommendations..

For the position of the LSX board in Huawei WDM equipment.

NOTE:

The FC1200 service is only supported by the TN12LSX /TN13LSX/TN14LSX.

When an XFP module is used as a WDM-side module on the TN13LSX board, the TN13LSX board does not support FC1200.

Universal Switch Architecture for Multiservice Grooming

Huawei OptiX OSN equipment uses a universal switch architecture for unified grooming of packet services and TDM services. OptiX OSN equipment can work in packet mode, TDM mode, or dual-domain (packet+TDM) mode.

The three modes can be smoothly switched by upgrading the software of a service board so carriers' requirements on services and networks can be met. The smooth switching between the three modes supports carriers' distributed smooth investment based on the development of the technology and industrial chain.

Based on a universal switch architecture, OptiX OSN equipment OSN 3500 uses the packet transmission technology to perform efficient statistical multiplexing on data services so the transmission cost of every bit is reduced. In addition, OptiX OSN equipment uses the Native technology to transmit TDM services so voice services are transmitted with high quality.

Figure 1 OptiX OSN equipment architecture 

Based on a universal switch architecture, OptiX OSN equipment unifiedly transmits packet services such as 2G, 3G, and VIP private line services so network overlapping is avoided. In addition, OptiX OSN equipment transmits TDM services. Carriers can constitute an end-to-end packet network, dual-domain (packet+SDH) network, or STM-64 board and Hybrid (MSTP+routers) network that bears L2+L3 services. This complete packet transmission solution allows an evolution from TDM networks to all-IP networks

Can Optical Ports Connecting Two Huawei Switches Work Normally If Their Transmit/Receive Power Is Abnormal?

When the power of optical ports connecting two switches is abnormal, either of the following

situations occurs:

When the transmit/receive power of the optical ports is too high, optical modules on the

ports may be damaged. In this case, connect an attenuator to the optical modules.

When the transmit/receive power of the optical ports is too low, error packets or packet

loss may occur on the optical ports or the ports may be Down. In this case, you are

advised to:

– Check whether the fiber length between the two ports is within the maximum transmission range of the optical modules on the ports.

– Check whether the fiber between the two ports is damaged.

– Use optical modules with a longer transmission distance on the two ports.

When connecting switches through optical ports, pay attention to the following points:

• The optical modules used on both ends must have the same wavelength.
• The receive power must be within the range required by the optical modules.
• The transmission distance of an optical module is affected by the optical fibers connected to it. For example, when Huawei OMXD30000 10GE SFP+ optical module on 10GE Switch uses OM1 multimode optical fibers, its transmission distance is 0.033 km. When this optical module uses OM3 multimode optical fibers, its transmission distance is 0.3 km.
• The optical modules used on both ends must have the same transmission speed, and the interface configurations on both ends must comply with related protocols.
• The type of optical modules used on the two ports is not restricted. For example, a port with an XFP optical module can communicate with a port with an SFP+ optical module bought with a cheap 10GE SFP+ port Switch, as along as they meet the preceding requirements.

What Can I Do If Two Connected Optical Ports on Huawei Switch Cannot Turn Up?

What Can I Do If Two Connected Optical Ports on Huawei Switch Cannot Turn Up?

Do the following if two connected optical ports cannot be up:

1. Check the port configurations. Ensure that the two ports are not shut down and have the
same duplex mode, rate, and negotiation mode.

2. Check the optical modules and fibers on switch like S6720-54C-EI-48S-AC. Ensure that the two ports use the same type of
optical modules, and the port rate is the same as the rate of optical modules. The optical
modules must match the fibers. Single-mode fibers are inserted into single-mode optical
modules and the multi-mode fibers are inserted into multi-mode optical modules.

3. Check whether the receive or transit power of the optical ports is within the allowed
range. If the receive or transmit power is excessively high or low, ports cannot turn Up.
The excessively long transmission distance or low optical fiber quality may also be the
reason why ports cannot turn Up.

4. If the preceding items are all normal, perform internal loopback test on the ports.
Connect the head and tail of a fiber to an optical module to check whether the port can
go Up.

You can also run the loopback internal command in the interface view to configure the
loopback function on Ethernet ports. This function can test port hardware performance
without connecting optical fibers to the port. If the port is Up, the port hardware is in
good condition.

5. If the fault cannot be located after the preceding operations are performed, replace the
optical modules or fibers.
