Summary on the RADIUS Authentication Implemented on Huawei OLT

Some FAQs in the implementation of RADIUS authentication:

Q: By default, the reported username for RADIUS authentication is with domain name. You can run the undo radius-server user-name domain-included command to exclude it. After this configuration, whether the domain name needs to be included in the username for logging in to the device?
A:Yes, the domain name must be included in the user username for logging in to the device no matter whether the user of RADIUS authentication has configured the username that excludes the domain name by running the undo radius-server user-name domain-included command.

Q:There are two domains existing on the MA5600T after the Radius authentication is configured: a default domain, and a huawei domain authenticated by Radius. If the default domain is deleted, does the domain name need to be included in the username for login?
A: Huawei MA5600T(V800R006C02): No matter whether the user uses the default username or configured username, the domain name must be included in the username for logging in. MA5600T (V800R007 and later versions): The username can be configured by running the terminal user authentication-mode AAA domain-name command. After the configuration, system will add a domain name for the username automatically when the user logs in to the RADIUS server for authentication.

Q: Can the username of RADIUS authentication can be displayed by running the display terminal user command?
AThe display terminal user command is used to query users without domain names.

Q:Why the user authority for Radius authentication is limited and does not support config mode?
A:The user with domain name has limited authority on the Radius server, and needs to configure the priority to 2 on the Radius to enter the config mode.

Q:Does Huawei OLT support the configuration that the local account can be used only when the user logs in through a serial port but cannot be used when the user logs in remotely?
A:MA5600T of version V800R006C02 does not support it. The V800R007 and later versions of MA5600T can support this configuration for some accounts (excluding the root and admin account): run the terminal user authentication-mode AAA domain-name command to set the authentication mode of the terminal user to AAA. In this case:
  • The system can add an .@huawei to the username that has no domain name.
  • The AAA account can be used to log in remotely, and the account can pass the authentication. If the local account is used to log in remotely, then the account cannot pass the authentication. However, the root and admin account can pass the authentication for remote login, other local accounts cannot.

What is the System Architecture of Huawei OTN OSN8800?


The 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.

System architecture of the OptiX OSN 8800 (MS-OTN) 
System architecture of the OptiX OSN 8800 (OCS) ]

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 like 40G TN54NS3 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 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 (TN52SCC) board 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.


FTTH Networking and Configuration Scenarios

Typical FTTH networking diagram 



Bridging ONT + HGW Network Scenario

The HGW integrating an IAD provides Internet, voice over Internet Protocol (VoIP), and Internet Protocol television (IPTV) services to users.

Services are implemented on the HGW, and the bridging ONT works with the OLT to provide Layer 2 channels.

Bridging+Voice ONT Network Scenario
The ONT integrating an integrated access device (IAD) provides Internet, VoIP, and IPTV services to users.
The bridging+voice ONT provides Layer 2 data and voice services. This scenario provides transparent transmission channels and requires simple service configuration, so this scenario applies to Layer 2 networking.
  • For data services, a PC directly performs dial-up. Then, the upper-layer broadband remote access server (BRAS) device authenticates and accesses the PC. The PC can also access the Internet using the Dynamic Host Configuration Protocol (DHCP) or static IP address.
  • The ONT with a built-in voice module encapsulates voice service packets, and the OLT transmits them to the upstream next generation network (NGN) or IP multimedia subsystem (IMS).

Gateway ONT Network Scenario
Huawei ONT integrating an IAD provides Internet, VoIP, and IPTV services to users.
The HGW ONT facilitates interconnection of home devices by providing Layer 3 services, such as Point-to-Point Protocol over Ethernet (PPPoE)/DHCP dial-up, network address translation (NAT), and Internet Group Management Protocol (IGMP) snooping. This scenario provides fine-grained management channels and service control, and applies to Layer 3 networking.

FTTH Deployment Schemes

FTTH service application includes the deployment process and service provisioning process. The FTTH deployment process includes OLT deployment (configuration) and configuration of basic data. No deployment, however, is required on the ONT and the ONT is plug and play once services are provisioned.
FTTH deployment schemes

Scheme
  • On the NMS: Profiles can be issued in batches.
  • Using commands on the OLT: Configuration scripts containing commands can be imported to the OLT.
  • Using the OSS: This method is recommended and it can implement automatic service provisioning, and eliminate problems caused by manual service provisioning, such as large workload, low efficiency, and difficult management.
  • Using OSS+ITMS: This method is recommended if the multiple private nodes are customized for carriers. Using a TR069 server, new gateways and value-added voice services can be simply added.
    • Layer 2 configuration data is issued on the NMS or OLT MA5603T or MA5600T.
    • Other configuration data such as voice, Layer 3, and Wi-Fi data is issued using the ITMS.
  • On the NMS: It applies to the scenario when no OSS is available and services need to be provisioned manually on the NMS.
  • On the ONT web page: When it is not feasible to provision services on the OSS or NMS, you can log in to the ONT web page and configure or modify parameters to provision services.
Parameter
  • DBA profile
  • Line profile
  • Service profile
  • IP traffic profile
  • Service level profile
  • Global OLT configurations (rather than FTTH user configurations) such as multicast VLAN, multicast mode, and policy of forwarding unknown packets
  • FTTH user service VLAN configurations including adding VLANs, setting the attributes of VLANs, and adding upstream ports for VLANs
ONT service provisioning parameters are classified into common parameters and customized parameters:
  • Customized parameters are usually issued by the upper-layer system during service provisioning.
  • Common parameters are usually configured at delivery or during data pre-configuration.

Some FAQ about Huawei OptiX OSN 7500 OSN3500 OSN 2500 and OSN1500

When engineers configure and management Huawei MSTP Equipment, there are many questions, below are some questions and answers that is we concluded.

Why Is the Query Result hpuneq or bipsd Although bipsd Is Sent in the SNCP Protection Mode?

Answer: The bipsd parameter is sent in the lower-order SNCP or PP protection mode. While querying the return result, we find that the value is hpuneq or bipsd. The two protection modes defined in the system occupy the same bit and are not differentiated in the callback parameter. As a result, both the two conditions are displayed.

Instructions on Parameters of the cfg-set-sncpattrib Command

Answer: OptCondition: b3sd, hptim, b3exc, hpuneq, lptim, lpslm, lpuneq, bipexc, bipsd, null;
A) For higher-order sncp, only b3sd, hptim, b3exc and hpuneq are valid.
B) For lower-order sncp, only bipexc and bipsd are valid.
C) For PP, lptim, lpslm, lpuneq, bipexc and bipsd are valid.
The host does not report an error for any parameter of “b3sd, hptim, b3exc, hpuneq, lptim, lpslm, lpuneq, bipexc, bipsd, null;” that is invalid for the current SNCP (or PP). In this case, the optional conditions in query operation are null.

When a Line Generates B2SD, AIS Is Inserted by Default, Which Results in Download Protection Switching or Service Interruption.

Answer: If a line generates b2sd, the PP or SNCP switching will occur and the switching state is sf. If the SNCP switching is not configured, the service will be interrupted. This is because that the specification of OSN3500 and OSN 2500 is to insert AIS (which should have been AUAIS) by default when a line generates b2sd. As a result, the corresponding channel is all “1”s and is unavailable. To prevent switching in this case, please disable b2sd with the cfg-set-alm2ais command.

Why Does Transient Happen to Timescale during the MS Switching Event?

Answer: The system clock has a frequency of 50 MHz, so the us counter divides 50 frequencies based on the system clock. The overflow value is not 0xffffffff,, but 0x051eb851.When the timescale goes to 0x051eb851, transient happens to it. 

The Switching Time Is Improperly Long under the Intersection of SNCP and MS

Answer: Both the MS and SNCP should be switched within 50 ms. In special networking, the switching time may be longer than 50 ms. In this case, we should analyze the networking and the fault.
SNCP is configured on one node. Therefore, when the NE at the intersection node is powered off, the two SNCP services are interrupted and the SNCP protection group still uses the working channel. After MS switching, the SNCP protection channel reports 1-second anti-jitter delay, so the switching takes a longer time.
Recommendation: The working and protection channels for the SNCP service run along different routes.

What are the main differences between N1 and N2 boards?

Answer: The board types of N1 and N2 boards are as follows:
N1 series boards: SSN1SEP1, SSN1SEP, SSN1SLQ1, SSN1SL1, SSN1SLQ4, SSN1SLD4, SSN1SL4, SSN1SL16
N2 series boards: SSN2SLQ1, SSN2SL1, SSN2SLQ4, SSN2SLD4, SSN2SL4, SSN2SL16, http://www.thunder-link.com/SSN4SL64LE642LC_p332.html?search=SL64SSN2SL64
The basic naming rules of the N1/N2 boards is that the chip name of Huawei is used for N1 boards (e.g., SD543 that is currently in use) and TSOT1610G is used for N2 boards.

The N2 boards support the TCM function while the N1 boards do not.

The N2 boards support service configuration and alarm of the Au3 level and higher-order path overhead maintenance of the AU3 level. The N1 boards do not support these functions.
As to loopback, the N2 boards support optical interface inloop and outloop, while the N1 boards support optical interface inloop and outloop and VC4 path inloop.
Both N1 and N2 boards support the reverse insertion of the AUAIS in inloop case but not in the outloop case.

Do you know the features of Huawei DSLAM MA5616?

10G GPON Upstream Transmission

  • 10G GPON provides a higher bandwidth to meet service requirements.
  • The 10G GPON transmission complies with ITU-T Recommendation G.987 and ITU-T Recommendation G.988, and provides asymmetric transmission rates of 2.5 Gbit/s in the upstream direction and 10 Gbit/s in the downstream direction.
  • 10G GPON networks can coexist with the current GPON networks to fully use the existing optical distribution network (ODN) resources.

Vectoring Broadband Service Speedup

Huawei MA5616 supports the vectoring technology to increase the very-high-speed digital subscriber line 2 (VDSL2) line rate.
VDSL2 is a mainstream mode for last kilometer access and shows increasing importance in bandwidth usage. VDSL2 uses high frequency bands and therefore the inter-line crosstalk has an evident impact on line quality. The bandwidth in multi-pair access scenario is much lower than the bandwidth in single-pair access scenario. Crosstalk becomes a major factor affecting the VDSL2 performance.
The MA5616 supports the vectoring technology, which uses vectoring groups to jointly transmit signals in the downstream direction and receive signals in the upstream direction of a VDSL2 line. This function of the MA5616 helps cancel the far-end crosstalk (FEXT) and improve VDSL2 line performance.
The vectoring function brings the following values for carriers:
  • Increases the bandwidth over a single cable within 500 m by 50% to 90%, reaching 95% of the theoretical value (without crosstalk).
  • After rate increasing, carriers can provide higher rates and more types of services for users, such as high-definition video.
NOTE:
Only when the system uses the CCUE control board, the MA5616 supports vectoring broadband service speedup.

Flexible Configurations

The MA5616 supports concurrent working of multiple types of service boards. Numbers of various ports are configured flexibly according to actual requirements, increasing the loading rate and meeting diversified customer demands. For details about the flexible configuration supported by the MA5616
Combo Boards and P2P Board
The MA5616 has a combo board design for supporting a high subscriber density. Combo boards save carriers' construction expenditure, require less deployment space, wiring workload, and time occupancy of the main distribution frame (MDF). Briefly, combo boards reduce carriers' maintenance costs.
  • The CALE board has a 32-port built-in splitter and supports service access of 32 asymmetric digital subscriber line 2 plus ADSL2+ ports and 32 plain old telephone service (POTS) ports.
  • The CVLC board has a 32-port built-in splitter and supports service access of 32 VDSL2 ports and 32 POTS ports.
The MA5616 provides the following point-to-point (P2P) boards to meet the requirements of P2P access for enterprises and VIP users.
  • The EIUD board provides four GE (optical or electrical) ports and four FE optical ports.

What features does Huawei ONT have?

Huawei ONT like HG8245, HG8546M, HG8247...Benifits


  • Provides better and user experience
  • Promotes the development of the OTT industrial chain for a win-win cooperation between carries and Internet companies.
  • Provides fine-grained bandwidth management, which reaches a balance between investment, income, and costs.

Highlights

Smart Pipe
The smart pipe identifies OTT service based on the domain name or DIP, modifies the DSCP/PBit value of OTT services to differentiate them from common internet services , and provides a high-speed channel for OTT transmission. Therefore, the smart pipe helps carriers to manage bandwidths.


Carriers provide high-speed cloud storage services.

Users enjoy high-speed and stable cloud storage services.

Association of One Account with Two POTS Ports

  • An Huawei ONT has multiple POTS ports but a household tend to have only one account. So, only one port is used. With the "Association of One Account with Two POTS Ports" function, you can use two POTS ports for calling through the same account.
POTS port 1 is for voice services and the phone number is 8888001. POTS port 2 is idle. The two phones can connect to POTS port 1 and port 2.

  • The two phones can be connected to any POTS port on the ONT.



SoftGRE-based WIFI Sharing


1. SoftGRE tunnels are established on a dedicated logic WAN or through HSI WAN ports. The intermediate network devices are free of SoftGRE configurations, so the deployment is simple.


2, The carrier can lease excess, dedicated SSIDs to other carriers.
The service continuity during WIFI hot spot handover is supported.
Common WLAN: service continuity during WI-FI hotspot handover not supported.


SoftGRE: ONT HG8240F works with Huawei WI-FI gateways (e.g. Huawei ME60, a center router). When the terminal has moved and switched to another AP, the IP address is unchanged for service continuity.
