Planning the Optical-Path-Shared MSP

Capabilities of Supporting the Optical-Path-Shared MSP

When planning the optical-path-shared MSP for Huawei OptiX OSN 2500, first consider the
capabilities of supporting the optical-path-shared MSP.
In the case of the optical-path-shared MSP, one optical interface can be configured into two
MSP groups. Thus, multiple MSP rings can share the same fiber and optical interface.
The OptiX OSN 2500 supports the configuration of the optical-path-shared MSP.
l The SF16 and SL16 boards can process two sets of K bytes, which are located in the first
and fifth STM-1s. The SF16 and Huawei SL16 boards support configuring a single optical interface
into a maximum of two MSP rings.

Planning Principles

To rationally and effectively plan the optical-path-shared MSP protection, the planning
principles should be followed.

In normal situations, in the case of the optical-path-shared MSP, two low-rate line units share
the same high-rate line unit.

In the optical-path-shared MSP, two line STM-16 units at the same rate can share the same line unit.

When the optical-path-shared MSP is configured, on the protection ring, the optical interfaces

in two directions need not be configured into paired slots.

Huawei MA5800 Configuring Alarms

Alarm management on Huawei MA5800 includes the following functions: alarm record, and alarm setting. These functions help you to maintain the device and ensure that the device works efficiently.

Context

An alarm refers to the notification of the system after a fault is detected. After an alarm is
generated, the system broadcasts the alarm to the terminals, mainly including the NMS and
command line interface (CLI) terminals.
Alarms are classified into fault alarm and recovery alarm. After a fault alarm is generated at a
certain time, the fault alarm lasts till the fault is rectified to clear the alarm.
You can modify the alarm settings according to your requirements. The settings are alarm
severity, alarm output mode through the CLI.
When managing alarms on the GUI through the NMS, you can set filtering criteria to mask
unimportant alarms and events. Such filtering function facilitates the focus of the important

alarms and eliminates the load of the NMS.

Procedure

Clear alarms.
You can run the alarm active clear command to clear the alarms that are not recovered
in the system.
– When an active alarm lasts a long time, you can run this command to clear the
alarm.
– Before clearing an alarm, you can run the display alarm active command to query
the currently active alarms.
l Configure alarm level.
Run the alarm alarmlevel command to configure the alarm level.
– Alarm levels are critical, major, minor, and warning.
– Parameter default indicates restoring the alarm level to the default setting.
– You can run the display alarm list command to query the alarm level.
– The system specifies the default (also recommended) alarm level for each alarm.

Use the default alarm level unless otherwise required.
Configure alarm jitter-proof.
Run the alarm jitter-proof command to configure the alarm jitter-proof function and the
jitter-proof period.
– To prevent a fault alarm and its recovery alarm from being displayed frequently,
you can enable the alarm jitter-proof function to filter alarms in the system.
– After the alarm jitter-proof function is enabled, the alarm in the system is not
reported to the NMS immediately but is reported to the NMS after an alarm jitterproof
period.
– If an alarm is recovered in an alarm jitter-proof period, the alarm is not reported to
the NMS.
– You can run the display alarm jitter-proof command to check whether the alarm
jitter-proof function is enabled and whether the alarm jitter-proof period is set.
– By default, the alarm jitter-proof function is disabled. You can determine whether to
enable the function according to the running of the device.
l Set or shield the output of alarms.
Run the (undo) alarm output command to set or shield the output of alarms to the CLI
terminal.
– Setting the output mode of alarms does not affect the generating of alarms. The
alarms generated by the system are still recorded. You can run the display alarm
history command to query the alarms that are shielded.
– When the new output mode of an alarm conflicts with the previous mode, the new
output mode takes effect.
– The output mode of the recovery alarm is the same as the output mode of the fault
alarm. When the output mode of the fault alarm is set, the system automatically
synchronizes the output mode of its recovery alarm. The reverse is also applicable.
Filter alarms reporting to NMS.
Run the trap filter alarm condition command to filter alarms that the device reports to
the NMS through traps.
The filtering criteria can be alarm ID, alarm severity, alarm type, subrack ID, subrack ID/
slot ID, subrack ID/slot ID/port ID, VLAN interface, and NE.
To reduce alarms and avoid alarm storms, the system does not send alarms of some
Huawei ONT to the NMS. To query the filtering criteria of alarms and events in the system, run
the display trap filter command.
l Query alarm configuration.
Run the display alarm configuration command to query the alarm configuration
according to the alarm ID. The alarm configuration that you can query includes the alarm
ID, alarm name, alarm class, alarm type, alarm level, default alarm level, number of
parameters, CLI output flag, conversion flag, and detailed alarm description.
(Optional) Configure alarm policy for ONT.
In Huawei FTTH scenarios, you can configure the ONT alarm policy profile to configure alarms
for different service policies.

What are the highlights of Huawei MA5800?

Smooth evolution to 40G/100G

The maximum bandwidth per service slotreaches 200 Gbit/s at the most, which supports the non-convergence access of 10G PON ports and supports 40G/100G PON boards in the future. Huawei MA5800 can smoothly evolve to 40G/100G PON without replacing subracks, which protects carriers' investments.

• PON access: GPON, 10G PON
• Upstream port: 2 x 100GE or 20 x 10GE/GE

Multi-service virtualized platform

One physical OLT is virtualized to multiple Huawei OLTs. All these virtualized OLTs can be separately configured and managed so that multiple services are carried over the same network.

• Multiple OLTs are combined into one, saving CO equipment room space.
• Software and hardware resources are isolated, assuring security and reliability.
• Domain-based management, making easy maintenance.

How to create personal topology view in U2000?

Issue Description

In T2000 customers had possibility to change topology position and coordinates of all NEs based on their needs. Each user could save personal topology view.
After U2000 installation (V100R003C00) it was impossible to save different topology for different user.

Alarm Information

null

Handling Process

To create custom view you need:
1. In U2000 main window chose View->create->view

2. Input custom view name, press "Topology" button and choose subnets or NEs you need (press right mouse button to choose needed NE or subnet)

3. Press finish when you finished to chose, then press OK.

4. After view is created you can chose different views by browsing "Current view" menu

5. You can change position on NEs, subnets and save view according to your requiremets. also you can modify or delete views

Root Cause

Really, in U2000 one database with NEs coordinates is used, so if one user change position of some NE and save topology, other users also see this change after they refresh page or relogin. Somethimes customers are upset because of these changes.
So we propose to use personal view for each user.
Each user can manage up to 5 custom views. User can modify only his own custom views.

Suggestions

Summary:
Personalization of topology view enhance operation and maintenance speed and convenience, however some features are not applicable for custom view and can be executed only from Physical Root (such as trail creation)

Planning the 1+1 &1:N Linear MSP on Huawei Optix OSN2500

Capabilities of Supporting the 1+1 Linear MSP

When planning the 1+1 linear MSP for the OptiX OSN 2500, first consider the capabilities of
supporting the 1+1 linear MSP.
In the case of Huawei OptiX OSN 2500, the capabilities of supporting the 1+1 MSP are as follows:

• The OptiX OSN 2500 supports the 1+1 MSP at the STM-64, STM-16, STM-4, and STM-1
• levels.
• An OptiX OSN 2500 system supports a maximum of 12 1+1 linear MSP groups.
• The switching and bridging mode supports the single-ended and dual-ended switchings.
• The switching revertive mode supports the revertive mode and non-revertive mode.

Planning Principles
To rationally and effectively plan the 1+1 linear MSP, the planning principles should be
followed.

Adhere to the following principles when planning the 1+1 linear MSP.

• Do not use different optical interfaces on one multichannel optical interface board to form,1+1 protection group. Otherwise, the protection function is unavailable when the board fails.
• The switching and bridging mode should be set to the single-ended switching.The switching revertive mode should be set to the non-revertive mode.
• It is recommended that you set the B2_SD as the trigger condition of the linear MSP ring protection switching.

Capabilities of Supporting the 1:N Linear MSP
When planning the 1:N linear MSP for the OptiX OSN 2500, first consider the capabilities of
supporting the 1:N linear MSP.
The OptiX OSN 2500 supports the 1:N linear MSP at the following levels:

• 1:N (1≤N≤14) linear MSP at the STM-16 level
• 1:N (1≤N≤14) linear MSP at the STM-4 level
• 1:N (1≤N≤14) linear MSP at the STM-1 level

In the case of the OptiX OSN 2500, the capabilities of supporting the 1:N linear MSP are as
follows:

• An OptiX OSN 2500 system supports a maximum of 12 1:N linear MSP groups.
• The switching and bridging mode is the dual-ended switching.
• The switching revertive mode is the revertive.

Planning Principles
Adhere to the following principles when planning the 1:N linear MSP.

• Do not use different optical/electrical interfaces on the same multichannel optical/electrical interface board to form a 1:N protection group. Otherwise, the protection function is unavailable when the board fails.
• In the 1:N protection scheme, the protection route can carry extra services, but the extra services cannot be protected.
• It is recommended that you set the WTR time of the linear MSP ring to 600s.
• It is recommended that you set the B2_SD as the trigger condition of the linear MSP ring protection switching.

Why I failed to Enable the CAU Function of the U2000 on my Computer?

Issue Description

I bought a Huawei MA5683T configure with one GPFD  C+, when I install U2000 server on computer, the U2000 client is installed remotely by using the computer according to the installation guide. After http://server IP address:8080/cau is entered in the address box, the web page cannot be displayed. The web page for client installation cannot be displayed on the local server, either. 

Alarm Information

The page cannot be displayed. 

The page you are looking for is currently unavailable. 

Handling Process

Check and confirm that the following conditions are met according to the installation guide. 

The default browser of Windows OS is Internet Explorer 6.0 or 7.0, and the proxy server is not set.

2. The U2000 server and CAU process are started up in the normal state. 

The U2000 server successfully communicates with the U2000 client and the bidirectional server-client ping operation is successful.

4. The port (port ID: 8080) on the U2000 server for installing the U2000 client in the network mode is enabled.

5. If the U2000 client has been installed in the network mode previously, uninstall the U2000 client and ensure that the .cau file in the %USERPROFILE% directory (such as C:\Documents and Settings\Administrator) is deleted. 

6. In addition to meeting the requirement for installation partition sizes, at least 900 MB space is available in disk C for data buffer. 

The CAU function, however, is still disabled. With the assistance of R&D engineers, it is confirmed that the CAU function is disabled by default when the U2000 is installed on a computer with smaller than 3 GB memory. Under this condition, the CAU function can be enabled only manually. To manually enable the CAU function, copy all files in the U2000\common\Tomcat\webapps\not_support\cau directory to the U2000\common\Tomcat\webapps\cau directory without restarting the system. Then, the CAU function is enabled immediately. 

Root Cause

The possible cause is that the port is being used or the CAU function is disabled. 

Suggestions

It is recommended that the limitation should be described in the installation guide. Engineers will encounter this problem after installing the U2000 because the computer memory of Huawei is smaller than 2 GB.
