The vRGW Configuration of connect-vlan

Function Description

The virtual residential gateway (vRGW) is used on the access network of a fiber-to-the-x (FTTx) solution and works together with an optical line terminal (OLT). The vRGW uses virtualization technologies to implement the Layer 3 home gateway (HG) function on the OLT. The HG function allows a carrier to manage home area networks in a centralized manner, adds no configuration on home area networks, reduces faults in home area networks, and lowers down the operation and maintenance (OM) cost.

Function

The connect-vlan command is used to add a management VLAN on the physical link between the control board and the vRGW board. To use a VLAN to carry the management traffic between the control board and the vRGW board, run this command.
The undo connect-vlan command is used to delete a management VLAN between the control board and the vRGW board. To delete a management VLAN that is no longer needed, run this command.

Format

connect-vlan vlanid
undo connect-vlan vlanid

Parameters

Parameter Description Value
vlanid Indicates the management VLAN ID. It uniquely identifies a VLAN. Numeral type. Range: 2-4093.

The vRGW Configuration of arp

Function Description

The virtual residential gateway (vRGW) is used on the access network of a fiber-to-the-x (FTTx) solution and works together with an optical line terminal (OLT). The vRGW uses virtualization technologies to implement the Layer 3 home gateway (HG) function on the OLT. The HG function allows a carrier to manage home area networks in a centralized manner, adds no configuration on home area networks, reduces faults in home area networks, and lowers down the operation and maintenance (OM) cost.

Function

The arp command is used to configure the static ARP mapping entries of the ARP mapping list. To configure a static mapping between an IP address and a MAC address, run this command.
The undo arp command is used to delete an ARP mapping list. The system can delete either the static ARP entry or the dynamic ARP entry.

Format

arp ip_addr mac_addr vlanid { frameid/slotid/portid [ ont ontid ] | frameid/slotid }
undo arp ip_addr [ vlanid ]

Parameters

Parameter Description Value
ip_addr Indicates the IP address of an ARP mapping entry. IPv4 address format. Dotted decimal notation.
mac_addr Indicates the Ethernet MAC address of an ARP mapping entry. Format: H-H-H. H indicates a hexadecimal number.
vlanid Indicates the VLAN ID. To send the frames with the destination address of mac-address through a specified VLAN, use this parameter. Numeral type. Range: 1-4093.
frameid/slotid/portid Indicates the shelf ID, slot ID, and port ID. Enter a slash (/) between the shelf, slot, and port IDs. Please see Differences Between Shelves.
frameid/slotid Indicates the shelf ID and slot ID. Enter a slash (/) between the shelf and slot IDs. Please see Differences Between Shelves.
ontid ontid Indicates the ONT ID. To send the frames with the destination address of mac-address through a specified ONT, use this parameter. Please see Differences Between Shelves.

Modes

Global config mode, MA5683T, MA5680T

Level

Operator level

Usage Guidelines

  • The ARP mapping list is a table for conversion between IP addresses into MAC addresses. It is used for communication between the hosts in a LAN.
  • In the initial state, the ARP mapping list is empty, and the ARP address mappings are dynamically obtained through the ARP protocol. In general, the ARP mapping list is dynamically maintained through the ARP protocol. The static ARP is needed only in special cases.
  • In the aggregation management scenario, static ARP entries should be configured on external ports of the slave subrack.

Example

To configure the MAC address corresponding to IP address 10.10.10.1 in a LAN to 00e0-fc01-0000 to which the packets are sent through port 0/19/0, do as follows: (Assume this port belongs to VLAN 10.)
huawei(config)#arp
{ aging-mode<K>|aging-time<K>|gratuitous-arp<K>|ip_addr<I><X.X.X.X>|learning<K>|proxy<K> }:10.10.10.1
{ mac_addr<P><XXXX-XXXX-XXXX> }:00e0-fc00-0000
{ integer<U><1,4093> }:10
{ frameid/slotid/portid<S><Length 5-18>|frameid/slotid<S><Length 3-15> }:0/19/0
{ <cr>|ont<K> }:

  Command:
          arp 10.10.10.1 00e0-fc00-0000 10 0/19/0
To configure the MAC address corresponding to IP address 10.10.20.1 in a LAN to 00e0-fc01-0022 to which the packets are sent through slot 0/2, do as follows: (Assume this port belongs to VLAN 100.)
huawei(config)#arp
{ aging-mode<K>|aging-time<K>|gratuitous-arp<K>|ip_addr<I><X.X.X.X>|learning<K>|proxy<K> }:10.10.20.1
{ mac_addr<P><XXXX-XXXX-XXXX> }:00e0-fc00-0022
{ integer<U><1,4093> }:100
{ frameid/slotid/portid<S><Length 5-18>|frameid/slotid<S><Length 3-15> }:0/2

  Command:
          arp 10.10.20.1 00e0-fc00-0022 100 0/2

Board Configuration(MA5600T/MA5603T)

This topic describes the type, name, slot and mapping of the boards supported by the
MA5680T/MA5683T.
This manual describes the supply of OLT boards supported by the product. However, the availability
of the boards is subject to the PCNs. For the availability of the boards, contact product mangers
at Huawei representative offices.
The MA5680T supports two service subracks: ETSI and IEC. The ETSI service subrack has two
more slots for service boards than the IEC service subrack, but they two support the same types
of boards. The MA5680T using the IEC service subrack mainly applies to the copper access
service. The following uses the ETSI service subrack as an example to describe the supported
boards on an MA5680T.
In the table, "Yes" indicates "supported" and "No" indicates "not supported".

MA5683T/MA5680T Integrated Access

The MA5680T/MA5683T is an integrated optical-copper access platform that provides flexible
user access modes and effectively ensures the smooth evolution from copper access to optical
access.
Optical Access
The MA5680T/MA5683T supports 10G GPON access, GPON access and P2P access, which
effectively meets requirements of various FTTx access applications.
Supports a split ratio of 1:128.
Support small form-factor pluggable (SFP) optical module of Class B+ or Class C+ and
XFP optical module, which can be used in different scenarios.
High-density 48 single-fiber bi-directional or 24 two-fiber bi-directional GE/FE P2P optical
access is supported.
Supports the high-performance and large-capacity control board SCUH. In active/standby
mode, SCUH supports 20 Gbit/s switching bandwidth for each slot. In load sharing mode,
SCUH supports 40 Gbit/s switching bandwidth for each slot. And provides 960G switching
capacity (doubles performance capacity), improving access user bandwidth.
Copper Access
The MA5680T/MA5683T supports multiple xDSL access and POTS access modes and makes
full use of existing copper cable resources to provide users with rich and flexible network
services. The retransmission and INM functions solve the line quality deterioration problem
caused by line bit errors and line noise, which ensures the line access quality.
The xDSL ports works with the ADSL terminal unit-remote end (ATU-R) or the VDSL
terminal unit-remote end (VTU-R), which can provides the highest-density 64 channels of
xDSL access and 48 channels of POTS access.
Far-end crosstalk (FEXT) is one of key factors affecting the performance and stability of
the VDSL2 system. The MA5603T supports the vectoring feature. Vectoring uses vectors
to solve FEXT of VDSL2 lines so as to improve bandwidth and performance of multi-pair
VDSL2 lines. It effectively decreases crosstalk for short-distance lines (shorter than 1 km).
The rate of a single VDSL line can be increased about 50%-90% within 800 m. Provides
higher bandwidth and more types of services over existing VDSL2 lines after the rate for
a single VDSL2 user is increased.
Full Service Access
This section describes the data, multicast, voice, and base station access services of the
MA5680T/MA5683T and the QoS solution implemented by the MA5680T/MA5683T.
Supports the High-Performance Multicast Service. The device employs the multicast
technology to provide IP video services, including live TV and QVoD, for carriers. By
introducing the multicast technology, the network device can manage, control, and forward
IP video services and thus meets carriers' requirements for provisioning IP video service.
The MA5680T/MA5683T has completed its interoperability test with all mainstream NGN/
IMSs.
– Connection to the NGN/IMS network through SIP or H.248, implementing the VoIP
service (including the voice, fax, and modem services).
– The MA5680T/MA5683T supports reconstruction of traditional voice devices such as
the N*64K private line device and ISDN PRI PBX, implementing the ALL IP
architecture.
Implements base station access solution by using MA5680T/MA5683T (OLT)+MDU. And
the MA5680T/MA5683T supports clock synchronization in the base station access
scenario.
The MPLS PWE3 provides the E2E reliability and quality assurance for the service.

xPON Access Port Common Management(port ont-auto-find)

port ont-auto-find

Function

This command is used to enable or disable the ONT auto-find function of a PON port. In general, if an ONT is added using the ont confirm(gpon) or ont confirm(epon) command, you must enable the ONT auto-find function. After the ONT auto-find function is enabled, the OLT periodically checks whether there are new online ONTs. If any ONT accesses the network, the SN (for a GPON ONT) or the MAC address (for an EPON ONT) of the ONT is reported to the OLT. Then, you can confirm the ONT according to the reported ONT information.

Format

port portid ont-auto-find switch

Parameters

Parameter Description Value
portid Indicates the ID of the PON port whose ONT auto-find function is to be configured. Please see Differences Between Shelves.
switch
Indicates the ONT auto-find function of a PON port.
  • enable: Enables the ONT auto-find function of a PON port. An ONT can be automatically found only after the ONT auto-find function is enabled. In such a case, run the ont confirm(gpon) or ont confirm(epon) command to confirm the ONT.
  • disable: Disables the ONT auto-find function of a PON port.
Enumerated type. Options: enable and disable.
Default value: disable.

Modes

GPON mode, EPON mode, MA5683T

Level

Operator level

Usage Guidelines

  • Run the config command to enter global config mode, and then run the interface gpon command to enter GPON mode, or run the interface epon command to enter EPON mode.
  • The ONTs from different manufacturers have different auto-find mechanism. Therefore, after the auto-find function is enabled, the ONT auto-find message may be reported a few minutes later.
  • You can run the display ont autofind command to query ONTs in auto-find state.

Example

To enable the ONT auto-find function of GPON port 0/3/0 to enable the OLT to periodically check whether there are new online ONTs, do as follows:

GPON Access Port Management(port range)

port range(gpon)

Function

The port range command is used to configure the maximum and minimum logical distances. During ranging for an ONT, the appropriate maximum and minimum logical distances can avoid long-term impact on normal services of other ONTs.
NOTICE:
After this command is executed, the ONT will be re-authenticated and go online again.
The undo port range command is used to restore the ranging compensation distance of a GPON port to the default value.

Format

port portid range { max-distance max-distance | min-distance min-distance }*
undo port portid range

Parameters

Parameter Description Value
portid Indicates the GPON port ID. Please see Differences Between Shelves.
max-distance max-distance Sets the maximum logical distance (maximum distance for short) of the ONT.
Numeral type. Range: 0-60 km.
  • GPON board: 0-60 km.
  • XG-PON board: 0-100 km.
Unit: km.
Default: 20 km.
min-distance min-distance Sets the minimum logical distance (minimum distance for short) of the ONT.
Numeral type. Range: 0-40.
  • GPON board: 0-40 km.
  • XG-PON board: 0-60 km.
Unit: km.
Default: 0.

Modes

GPON mode

Level

Operator level

Usage Guidelines

  • Run the config command to enter global config mode, and then run the interface gpon command to enter GPON mode.
  • Ranging refers to the OLT calculation of the delay of each ONT based on the physical distance of the ONT to prevent the conflict of the upstream data from different ONTs.
  • When the ranging starts, the OLT sends a ranging message to the ONT and starts waiting for the ONT response. When the OLT(like MA5683T) is waiting for the ONT response, the services of the other ONTs are unavailable. Therefore, the period of waiting for the ONT response needs to be shortest-possible.
    • Usage of the minimum distance: After sending a ranging message, the OLT determines beforehand the start time of waiting for the ONT response according to the preset minimum distance.
    • Usage of the maximum distance: After sending a ranging message, the OLT determines the end time of waiting for the ONT response according to the preset maximum distance.
  • Ensure the following when configuring the minimum and maximum distances:
    • For GPON boards, maximum distance - minimum distance <= 20 km
    • For XG-PON boards, maximum distance - minimum distance <= 40 km
    • Actual physical distance between the OLT and ONT ≈ (maximum distance + minimum distance)/2

Example

To set the minimum logical distance of the ONT connected to GPON port 0/3/0 to 5 km, and the maximum logical distance to 15 km so that the actual distance between the ONT and the OLT is within the ranging distance, do as follows:
huawei(config-if-gpon-0/3)#port  
{ optical-alarm-profile<K>|portid<U><0,7> }:0                                                            
{ fec<K>|laser-switch<K>|ont-auto-find<K>|ont-password-renew<K>|range<K> }:range
{ max-distance<K>|min-distance<K> }:min-distance                                
{ min-distance<U><0,40> }:5                                                     
{ <cr>|max-distance<K> }:max-distance                                           
{ max-distance<U><0,60> }:15                                                    
                                                                                
  Command:                                                                      
          port 0 range min-distance 5 max-distance 15                           
  This command may cause the re-registration of the ONT connected to the port.                
  Are you sure to execute this command? (y/n)[n]: y
To restore the maximum and minimum logical distances of the ONT connected to GPON port 0/3/0 to default values, do as follows:
huawei(config-if-gpon-0/3)#undo port  
{ optical-alarm-profile<K>|portid<U><0,7> }:0                                                            
{ range<K> }:range                                                              
                                                                                
  Command:                                                                      
          undo port 0 range                                                     
  This command may cause the re-registration of the ONT connected to the port.                
  Are you sure to execute this command? (y/n)[n]:y

To set the minimum logical distance of the ONT connected to XG-PON port 0/3/0 to 10 km, and the maximum logical distance to 50 km so that the actual distance between the ONT and the OLT is within the ranging distance, do as follows:
huawei(config-if-gpon-0/3)#port  
{ optical-alarm-profile<K>|portid<U><0,7> }:0                                                            
{ fec<K>|laser-switch<K>|ont-auto-find<K>|ont-password-renew<K>|range<K> }:range
{ max-distance<K>|min-distance<K> }:min-distance                                
{ min-distance<U><0,60> }:10                                                     
{ <cr>|max-distance<K> }:max-distance                                           
{ max-distance<U><0,100> }:50                                                    
                                                                                
  Command:                                                                      
          port 0 range min-distance 10 max-distance 50                           
  This command may cause the ONT connected to the port abnormal.
  Please re-register all of the ONTs connected to the port manually.

To restore the maximum and minimum logical distances of the ONT connected to XG-PON port 0/3/0 to default values, do as follows:
huawei(config-if-gpon-0/3)#undo port  
{ optical-alarm-profile<K>|portid<U><0,7> }:0                                 
{ range<K> }:range                                                              
                                                                                
  Command:                                                                      
          undo port 0 range                                                     
  This command may cause the ONT connected to the port abnormal.
  Please re-register all of the ONTs connected to the port manually.
