Can I use Huawei ONU MA5626 as a switch?

Can I use GPON ONU MA5626 as a switch?

Huawei MA5626 is not recommended as a switch. 

During routine operation and maintenance, you can configure the MA5626 as a switch through command lines if needed. 

1. Log in to the MA5626. The default user name and password are root and mduadmin respectively. 

2. Enter config mode. 

cmd: 

MA5626>enable

MA5626#config

MA5626(config)#

3. cmd:

vlan service-profile profile-id 1 profile-name "srvprof-1"//Configure a VLAN service profile. 

user-bridging enable //Enable the user bridging mode. 

commit //Confirm and execute the command. 

4. cmd: 

vlan bind service-profile 100 profile-id 1 //Bind the VLAN to be configured for a port to the VLAN service profile. 

5. cmd: 

service-port vlan 100 eth 0/1/1 multi-service user-vlan untagged  rx-cttr 6 tx-cttr 6 //After configuring port data, configure the MA5626 as a switch.

How to expand Value-Added card VSUF-160 forwarding capability?

VSUF-160 ME0DVSUFD070 is a flexible value-added service processing card on Huawei BRAS ME60, it can provide a forwarding capability of 400 Gbit/s. If forwarding capability expansion required, there are two ways:

1, 20G license

A 20G license expands the forwarding capability of a VSUF-160 by 20 Gbit/s. A VSUF-160 supports a maximum of two 20G licenses.

2, SP160 

An SP160 ME0D00SPD070  provides a forwarding capability of 40 Gbit/s. A VSUF-160 supports a maximum of two SP160s.

To enable a VSUF-160 to provide a forwarding capability of 160 Gbit/s, install two 20G licenses and two SP160s on the VSUF-160.

Note: ME60-X8, installing the VSUF-160s in slots 3, 4, 5, and 6 is recommended. On the ME60-X16, installing the VSUF-160s in slots 3, 4, 5, 10, 11, 12, 13, and 14 is recommended.

In 70 A PEM scenarios, the fourth partition of an ME60-X16 chassis supports five LPU/VSU slots but can support only a maximum of four VSUF-160s/VSUF-160-Es. That is, an ME60-X16 chassis supports a maximum of 15 VSUF-160s/VSUF-160-Es. An ME60-X8 chassis can be fully configured.

The VSUF-160 is supported only on the ME60-X8 and ME60-X16 and must work with the 200G SFU.

How to configure a primary IP Address for an interface on Huawei Switch?

Procedure

1.    Run system-view

The system view is displayed.

2.    Run interface interface-type interface-type interface-number[.subinterface-number]

The interface view or sub-interface view is displayed.

·         Only Huawei S5720-EI, S5720-HI, S5730-HI, S6720-EI, S6720-HI, and S6720S-EI support Ethernet sub-interfaces.

·         Only hybrid and trunk interfaces on the preceding switches support Ethernet sub-interface configuration.

·         After you run the undo portswitch command to switch Layer 2 interfaces on the preceding series of switches into Layer 3 interfaces, you can configure Ethernet sub-interfaces on the interfaces.

·         After an interface is added to an Eth-Trunk, sub-interfaces cannot be configured on the interface.

·         VLAN termination sub-interfaces cannot be created on a VCMP client.

3.    (Optional) On an Ethernet interface, run undo portswitch

The interface is switched to Layer 3 mode.

By default, an Ethernet interface works in Layer 2 mode.

Only the S5720-EI, S5720-HI, S5730-HI, S6720-EI, S6720-HI, and S6720S-EI support switching between Layer 2 and Layer 3 modes.

4.    Run ip address ip-address { mask | mask-length }

A primary IP address is configured for the interface.

By default, no IP address is configured for an interface.

Each interface has only one primary IP address. If you configure a new primary IP address for an interface, the original one is deleted and the new primary IP address takes effect.

What is the Working Principle and Signal Flow of Huawei STM-4 service board SLD4A?

SLD4A consists of the O/E converting module, CDR module, SDH overhead processing module, logic and control module, and power module. 

SLD4A can apply to Huawei MSTP equipment OSN1500B, OSN2500, OSN3500 and OSN7500.

Figure 1 shows the functional block diagram of the SLD4A.

Figure 1 Functional block diagram of the SLD4A

The functional modules of the STM-4 units are described as follows:

O/E Converting Module

• Converts the received optical signals into electrical signals, in the receive direction.
• Converts the electrical signals into SDH optical signals, and then sends the SDH optical signals to fibers for transmission, in the transmit direction.
• The SPI detects the R_LOS alarm and provides the laser shut down function.

CDR Module

This module restores the clock signal.

SDH Overhead Processing Module

this module includes the RST, MST, MSA, and HPT sub-modules. This module provides the inloop and outloop functions.

• RST sub-module
  • In the receive direction, the RST sub-module terminates the regenerator section overhead (RSOH). That is, the RST sub-module detects the frame alignment bytes (A1 and A2), descrambles all the bytes except the first line of the RSOH, restores and checks the regenerator section trace byte (J0), and checks the B1 byte.
  • In the transmit direction, the RST sub-module generates the RSOH. That is, the RST sub-module writes bytes such as A1, A2, and J0, calculates and writes the B1 byte, and scrambles all the bytes except the first line of the RSOH.
• MST sub-module
  • In the receive direction, the MST sub-module terminates the multiplex section overhead (MSOH). That is, the MST sub-module generates the multiplex section-alarm indication signal (MS_AIS) alarm and detects the multiplex section-remote defect indication (MS_RDI) alarm after detecting the K2 byte, and detects the multiplex section-remote error indication (MS_REI) alarm and generates the B2-excessive errors (B2_EXC) alarm after checking the B2 byte.
  • In the transmit direction, the MST sub-module generates the MSOH. That is, the MST sub-module writes bytes such as E2, D4-D12, K1, K2, S1, and M1, and calculates and writes the B2 byte.
• MSA sub-module
  • In the receive direction, the MSA sub-module de-interleaves the administration unit group (AUG), divides an AUG into N AU-4s, detects the administration unit-loss of pointer (AU_LOP) alarm and the administration unit-alarm indication signal (AU_AIS) alarm, and performs pointer justifications.
  • In the transmit direction, the MSA sub-module assembles the AUG and generates the AU-4. N AU-4s are multiplexed into an AUG through byte interleaving.
• HPT sub-module
  • In the receive direction, the HPT sub-module terminates the path overhead (POH). That is, the HPT sub-module detects the higher order path-remote error indication (HP_REI) alarm after checking the B3 byte, generates the higher order path-trace identifier mismatch (HP_TIM) alarm and the higher order path-signal label mismatch (HP_SLM) alarm and detects the higher order path-remote defect indication (HP_RDI) alarm after detecting the J1 and C2 bytes, and generates the higher order path-unequipped (HP_UNEQ) alarm after detecting the C2 byte.
  • In the transmit direction, the HPT sub-module generates the POH. That is, the HPT sub-module writes bytes such as J1 and C2, and calculates and writes the B3 byte.

Logic and Control Module

• Manages and configures the other modules of the board.
• Performs inter-board communication through the internal Ethernet interface.
• Traces the clock signal from the active and standby cross-connect units.
• Controls the laser.
• Passes the orderwire and ECC bytes through an ADM that consists of two paired slots when the GSCC is not in position.
• Selects the clock signal and frame header signal from the active and standby cross-connect units.
• Controls the indicators on the board.

Power Module

It converts the –48 V/–60 V power supply into the DC voltages that the modules of the board require.
