As a model and standard of software development, the Common Object Request Broker Architecture (CORBA) provides necessary services and toolkit to develop software. The CORBA northbound interface (NBI) functions to integrate the distributed software at the element management layer with that at the network management layer. The CORBA NBI has the following features: Complying with the CORBA 2.3 specification of the Object Management Group (OMG) and supporting the IIOP 1.1 and IIOP 1.2. Adopting the standard CORBA Naming Service 1.1 and Notification Service 1.0. The current version that uses The ACE ORB (TAO) 1.3 is highly efficient. Capable of being smoothly transplanted to other ORB platforms. It supports the interconnection between different ORB platforms, including: – IONA Orbix2000 – IONA Orbix 6.1 – InterBus – JacORB – Borland VisiBroker – Borland BES

Supporting cross-platform operation – Windows 2000, Windows 2003, Solaris 8, Solaris 10

P-4

The CORBA NBI complies with the following standards recommended by the Tele Management Forum (TMF): TMF 513 V2.1 TMF 608 V2.1 TMF 814 V2.0 (IDL V2.1)



P-5

Network element (NE): It refers to the device in the network. The NE reports alarms to the element management system (EMS) . EMS: The network devices provided by Huawei can be managed by the iManager U2000. The iManager U2000 is at the EMS layer and interconnects with the thirdparty NMS through the NBI. NMS: It refers to the NMS of a carrier. CORBA NBI: It provides an interface for the superior NMS to access the EMS.



Querying the Current Alarms of the EMS and All NEs in Real-Time

This function allows the superior NMS to deploy services such as SDH, WDM path creation, active, deactive, delete, etc.

Current performance querying

This function allows the superior NMS to query the resource information such as the main type of EMS resource, topology information of EMS, etc.

Service deployment

This function allows the EMS to report the resource changing information to the superior NMS .

Resource querying

This function allows the superior NMS to synchronize alarm information with the EMS.

Resource changing report

This function allows the superior NMS to set the filtering rules for the EMS or NE alarms and set the alarm severity levels, event type, and device type to filter the alarms.

Alarm Synchronization

This function allows the superior NMS to query the current alarms of the EMS and all NEs and set alarm severity levels to filter the alarms. The filter for the notification service does not affect the query result. The current alarm refers to a fault alarm that is uncleared and unacknowledged, uncleared but acknowledged, or cleared but unacknowledged. NMS can obtain the real-time alarms of the EMS and NEs. The EMS detects the alarms returned to the caller. The NMS needs to perform this task periodically to obtain the real-time alarms.

Filtering Alarms

P-6

This function allows the superior NMS to query the current performance data.

History performance querying

This function allows the superior NMS to query the historical performance data. Confidential Information of Huawei. No Spreading Without Permission

There are three parts of the CORBA interface: standard naming service, notifying service and CORBA agent. Naming service: provides the interface for the OSS to access the U2000 CORBA. The uniqueness of the name of the EMS must be guaranteed in the NMS management domain. Notifying service: is responsible for the adding/deleting events monitoring, receiving alarm/performance/report. CORBA agent: transform the internal data of U2000 to the CORBA data complying with the international standard and transform the request from OSS to the internal data of U2000 to guarantee the integration of OSS and U2000.



P-9

IDL: Interface Definition Language. IDL is not a programming language and its only purpose is to allow the CORBA interface being defined as a programming language independent mode, and allow the inter-operation of applications programmed with different languages. IDL can not be programmed and compiled, and is only applicable to describe the CORBA interface and define the data type of the objects. Language mapping defines how to translate the IDL file into different programming languages. The third party software can be used such as TAO, JacORB. Huawei uses TAO to translate CORBA language into C++. NMS and EMS invoke functions such as getNEName{} to query and report alarm, resource, and performance information.



P-10

getEMSSession: Obtain the reference of Ems Session to set up a session. getEventChannel: Obtain an event channel. getSupportedManagers: Obtain the name list of the Manager objects supported by the EMS. getManager: Obtain the object reference of the specified Manager.



P-11

When OSS connects to U2000, U2000 establishes a session between them. U2000 performs the “ping” every 30 seconds and if there is no reply to the “ping” for 4 times, U2000 will abort the session; meanwhile, U2000 sends a heartbeat notifying message to OSS every 30 seconds.



P-12

getAllManagedElements: Query the NE resource information of the EMS and all NEs getAllActiveAlarms: Query the current alarms of the EMS and all NEs getAllCurrentPMData: Query the current performance data of the EMS and all NEs NT_ALARM: Alarm notifying

CORBA NBI software component is controlled by MSUITE. The U2000 installation package has integrated the MSUITE software, after installing the U2000, the MSUITE is installed together. So there is no need to install the MSUITE separately. CORBA Agent also need the license support. Without license, it does not work. After the MSUITE is started, we need to configure some parameters of CORBA Agent. Steps to start the MSUITE:

Click the MSUITE icon on the desktop or click the program below: %MSUITE%\engineering\ startclient.bat.

Enter the IP address and the user name, password to login MSUITE. After login, select NBI > Configure CORBA Interface Instance from the main menu to configure the CORBA NBI parameters.

Note:

If you need to install CORBA component, select Deploy > Add Component from MSUITE to add CORBA NBI. After that, you should restart U2000 server.


P-17


Notify Service: Namely TAO notification service, it is a non-persistent notification service and the default deployment type of the U2000. Orbix Notify Service: Namely Orbix notification service, it is a persistent service. That is, when the upper layer NMS is disconnected from the U2000 abnormally, the notification component can save the notification events generated by the U2000 during this period of time to the disk or memory. After the connection between the upper layer NMS and the U2000 recovers, the notification component reports the saved notification events to the upper layer NMS. If the connection between the upper layer NMS and the U2000 is normal, the notification component does not save any notification event. If the Orbix notification service is required, you need to purchase a license from the component developer, then rename the license file to license.txt and save it in the %IMAP%/../cbb/nbi/nbicbb_3p/tools/orbix/etc/ directory. Default Value of Port Common Mode Naming service port: 12001 Notify service port: 12002 CORBA Agent port: 12003

iManager U2000 SNMP Interface


P-0



P-1


P-2

At the beginning, the network and service are simple. We can use ICMP and Ping command to manage and monitor the network. As time went by, the Ping command cannot manage the network. How to develop the new NMS protocol which is easy to the maintenance engineer is the next step for R&D. In this background SNMP (Simple Network Management Protocol) is developed.



P-3

SNMP is in the application layer of the TCP/IP stack; SNMP is above the UDP layer and the default UDP port number is 161 between NE and U2000; SNMP trap message is used to send the emergency information to NMS voluntarily, when there is a link down. SNMP trap uses UDP port 162; SNMP has three versions

SNMP v1 uses community for authentication , SNMP v1 can’t provide encryption. SNMP v2 improved SNMP v1 with a new concept named getbulk , it can provide more error message , but still can not provide encryption. SNMP v3 improved the security with USM (User Security Module) and VACM (View-based Access Control Model), USM is used for encryption ,and VACM is used for access control.

SNMPv3 is not widely supported, U2000 can support all the versions.



P-4

Many telecom level equipment support SNMP, such as Huawei Access and IP equipment. If we enable the SNMP function, and then the U2000 is server for the equipment. In this case, SNMP is a southbound interface for U2000.

Actually, SNMP is a type of NBI of U2000, which will transfer data to higher layer OSS. The relationship between SNMP and COBRA:

The basic function of SNMP and COBRA is to report the information to upper level NMS; SNMP is protocol which is applied between NMS and EMS or EMS and NEs; but COBRA is only applied between NMS and EMS;

COBRA is more security than SNMP in data transfer.



OSS（（Operating Support System））

Software which runs on the workstation or PC to manage and monitor the whole network.

Agent

P-5

Process which run on the managed equipments or low level NMS (U2000). When it receive the requirement from the OSS, the Agent will give response. The main function is collecting the status information of the NEs, the realizing the remote operation from the NMS to NEs, and sending the alarm message to the OSS.

MIB

MIB (Management Information Base), is the virtual database, and it is status set which is in the managed object. Normally the agent query the equipment status from the MIB, and the MIB will reply it from its tree topology structure directory. MIB (Management Information Base).

SNMP NBI is the communication protocol between the OSS and Agent, it includes two parts:

OSS;

SNMP Agent.



P-6

SNMP is divided into NMS U2000 and AGENT. U2000, the NMS sends request to Agent. Agent is a process or task residing in managed equipment. When Agent receives the enquiry packet from the NMS, it performs decoding analysis and gets value of management variable from relevant modules. Then it generates Response message, sends the packet back to the NMS after it is encoded. SNMP is the application layer protocol that defines the transfer of management information between NMS and Agent.



P-7

To simplify the development of the Agent side, SNMP only defines two kinds of operations --- Get and Set. Get is used to obtain management information from managed equipment. And Set is used to configure managed equipment via setting the value of variable. NMS and Agent transfer management information to each other via packet. And SNMP V1 only defines five kinds of packets: Get Request packet: Used to get the value of specified management variable. GetNext Request packet: Used to continuously get the values of a group of variables. GetResponse packet: Used to respond request, return value for request or error type, etc. Set Request packet: Used to set the specified management variable. Trap packet: Used for managed equipment to send information to NMS initiatively in urgent cases. GetRequest and GetNextRequest are used to obtain information of the managed object in NM. SetRequest is used to configure the managed object. These three kinds of requests correspond with three kinds of SNMP messages. Agent responds them via sending GetResponse message. Trap is generated by Agent. It is used to report abnormal event of the managed equipment to the NM. Agent will send Trap to notify NM when equipment gives alarm or important data is changed by user/console/other NMs. When SNMP Manager receives the Trap, relevant actions will be initiated, such as diagnosing fault via polling, adopting recovery measures, modifying relevant database of the NM.



P-8

SNMP is base on TCP/IP, and it is in the application layer of TCP/IP. SNMP provides one simple command set for communication, and it use UDP to send and receive massage between NMS and Agent.

Version: version of SNMP;

Community: user name of NMS to login Agent.

SNMP PDU：SNMP PDU（Protocol Data Unit), SNMP protocol message payload, querying and acknowledge command and so on.



Normally:

P-9

The OSS will send message to Agent, such as request operations, after the Agent receive the message, at first, it will check the version, community and operation objective of SNMP message. If they are matched, the Agent will give the feedback message and report what the OSS want to know.

In emergency:

Such as the NIC port is down and repaired, and then the Agent will send TRAP message to OSS to establish the link again.



P-10

1. The agent receives an SNMP request packet from the NM station through UDP port 161.

2. The agent decodes the packet based on ASN.1 basic coding rules and represents it in an internal data structure. The agent discards the packet if there is a decoding failure. 3. The agent gets the version number from the packet. The agent discards the packet if the version is inconsistent with the SNMP version it supports. 4. The agent gets the community name from the packet. The community name is filled by the NM station that sends the request. If the community name is inconsistent with that of the agent, the packet is discarded. A trap message or an Inform packet is generated simultaneously. 5. The agent gets PDUs from the authenticated ASN.1 object. If the agent fails to get the PDUs, the agent discards the packet; otherwise, the agent processes the PDUs. 6. The agent processes PDUs differently and gets the management variables of the corresponding protocol modules by searching nodes that correspond to management variables in the MIB.

7. The agent encapsulates the values of management variables in a PDU, uses the source IP address and port of the request packet as the destination IP address and port, and adds the SNMP version number. A response packet is then generated. After being coded, the response packet is sent to the NM station.

SNMP NBI software component is controlled by MSUITE. The U2000 installation package has integrated the MSUITE software, after installing the U2000, the MSUITE is installed together. So there is no need to install the MSUITE separately. SNMP Agent also need the license support. Without license, it does not work. After the MSUITE is started, we need to configure some parameters of the SNMP.

Steps to start the MSUITE:

Click the MSUITE icon on the desktop or click the program below: %MSUITE%\engineering\ startclient.bat. Enter the IP address and the user name, password to login MSUITE. After login, select NBI > Configure SNMP Interface Instance from the main menu to configure the SNMP NBI parameters.

Note:

If you need to install SNMP component, select Deploy > Add Component from MSUITE to add SNMP NBI. After that, you should restart U2000 server.

When the third-party NMS uses the SNMP v1 or v2c protocol, the authentication control between the SNMP agent and the upperlayer NMS is implemented through community information. To be specific, only when the set community is the same as that of the upper-layer NMS, the third party NMS responds to the alarm query requests received. Otherwise, the third-party NMS ignores the requests.

The default read/write community is public/private. You can also enter any character string consisting of 255 characters at most.

security management strategy: The security management function provides the rolebased and domain-based management for the U2000 and NEs. With this function, the U2000 can also monitor in real time the users that already log in to the U2000 and NEs. In this way, the network and data security ensures that login failures or illegal operations are captured.



After installing U2000 on Solaris platform, there will be three system users: root, sybase, nmsuser. Usually we use nmsuser to log in the JDE and start U2000 server.

P-5

root: this user is the super user of the OS and it has the highest authority in the system. The root user is used to create other users with relevant authorities. The default password of root is rootkit. sybase: this user is the database operation user. It is responsible for setting Sybase environment variables, installing, maintaining and managing the Sybase database, As the owner of the directory /opt/sybase, the sybase user can manage the Sybase database, for example, configuring Sybase environment variables and starting/stopping the Sybase service. nmsuser: During the U2000 installation, the software creates a nmsuser user of the operating system automatically. The nmsuser user is responsible for setting environment variables of the U2000 server and starting the U2000 server. The nmsuser user has all the rights of its home directory. The file .profile in this directory records environment variables for the U2000 running.

After database initialization, there are two default users: sa and NMSuser.

sa is the super user of the database. The default password is ‘changeme’. NMSuser is the database user which is used for U2000 to login database. The default password is NMSuser

NM User: The one to login U2000 Server.

NE User: The one to login NEs by U2000 or other software. Confidential Information of Huawei. No Spreading Without Permission


P-6

The logs include the U2000 security log, the U2000 operation log, the system logs and the NE log. The logs record operations performed by operators to the U2000 or an NE.

Security logs record the security operations that the user performs in the U2000, for example, login, logout, locking, and unlocking. By viewing the logs, an administrator can track and check the security operations of the users. Operation logs record the information about the non-security operations that the user performs in the U2000, for example, creating subnets, and muting and unmuting the alarm sound. By viewing the logs, an administrator can track and check the user operations. System logs record the operations or tasks that the U2000 performs automatically, for example, scheduled tasks and system tasks. The NE syslog running logs record the running information of U2000 NEs. By obtaining all NE syslog running logs from NEs through the U2000, you can view the NE syslog running logs managed by the U2000 through the U2000, instead of viewing the NE syslog running logs on each NE.

For network maintenance purposes, you can create U2000 users and assign different authorities to them. Apart from user admin, all the users to operate the U2000 need to create corresponding accounts, that is, the U2000 user accounts.



P-22

You can specify the user group of a U2000 user so that the user can have the management rights and operation rights of the user group.

Usually, we assign the user with certain user authorities by adding the user to a user group rather than assigning specific authorities for the user. Procedure:

Choose Administration > NMS Security > NMS User Management from the Main Menu In the NMS User Management area, double-click Users and select a desired user

In the right-hand pane, click the Groups tab

Optional: Select a desired user group and click Delete

Click Add and the Add User Groups dialog box is displayed

Select a user group that you want to add, and click OK

In the right-hand pane, click the Operation Rights tab

Optional: Select a desired user operation rights and click Delete

Click Add and the Add Rights dialog box is displayed

Select a user group that you want to add, and click OK



P-23

User Group: This is a collection of the U2000 users that have the same management rights. The default user groups are maintainer group, manager group, monitor group, operator group and security manager. The attributes of the user groups include name, description, member and authority.

Procedure:

Choose Administration > NMS Security > NMS User Management from the Main Menu. In the NMS User Management area, double-click User Group, right-click and choose New User Group from the shortcut menu. In the New User Group dialog box that is displayed, input the information of a new user group. Click OK.



P-24

The principle of assigning user authorities is as follows:

After creating a U2000 user, you assign the user with certain user authorities by adding the user to a user group rather than assigning specific authorities for the user. If the user authorities are limited, and the user cannot perform certain operations after the user is added to a default user group, you can create user group. After adding authorities to this user group, you can assign the user to this new user group. In practice, you may need to add or delete specific authorities for a user without creating new user groups. In this case, follow the rules below.

To modify specific authorities for a number of NEs, do not directly select these NEs. Creating an Object Set for the NEs that require more authorities, and assign authorities for the equipment set. To assign a number of operation authorities to a user, do not directly select all these operation authorities. Creating an Operation Set for these operations and assign the operation set to the user. If you want to add one or more authorities to a user, you can select the user that you want to set the authority directly. Select the Operation Rights tab, and click ‘select’ to add the corresponding operation authorities to the user.



P-25

Operation Set: This is a collection of client-side operations. Operation sets are established to facilitate the user right management. Different client-side operations have different impacts on the system security. Those operations that impose similar impacts on the system security are allocated to the same operation set. In this way, if a user (or user group) is authorized with the rights of an operation set, the user (or user group) can perform all the operations in the operation set. If the default operation sets do not meet the requirements for the right allocation, you can create new operation sets as required.

Procedure:

Choose Administration > NMS Security > NMS User Management from the Main Menu. In the NMS User Management area, right-click Operation Set and choose New Operation Set from the shortcut menu. In the New Operation Set dialog box displayed, input the information of a new operation set. Click the Members tab. Check the Select button (display in the slide) or Copy member from operation button to add members to the operation set. Click OK.

U2000 supports modifying an operation set, deleting an operation set, exporting or importing operation sets.



P-26

Object Set: It is a collection of manageable devices and device services. By default, the U2000 provides All Objects. If a user or user group can manage an object set, it indicates that the user or user group can manage all the objects in the object set. The administrator can create an object set, add objects that can be managed in a centralized manner to the object set, and specify a user or user group to manage the objects in the object set. In this way, the management cost of the administrator can be reduced.

Procedure:

Choose Administration > NMS Security > NMS User Management from the Main Menu In the NMS User Management area, click Object Set, right-click and choose New Object Set from the shortcut menu In the New Object Set dialog box that is displayed, input the information of a new equipment set Click the Members tab. Check the Select button (display in the slide) or Copy members from object button to add device to the object set.

Click OK.

U2000 supports modifying an object set, deleting an object set.

You can back up and restore the U2000 data in two ways: Back up and restore all data in U2000 databases, and back up and restore the U2000 network configuration data by using scripts.

The following data is not backed up when you back up the U2000 database:

The data save at the NE side that cannot be uploaded.

The custom options of the system.

Comparison of Two Data Maintenance Methods Method

Characteristics

Application Scenario

Backing up and restoring all data in the U2000 databases

1. Backs up the structure and contents of the U2000 database. The data is in the binary mode. 2. Backs up all data. 3. The processing speed is fast, and the backup file is big.

The backed up data for a certain type of database cannot be restored to the data for a different type of database.

Backing up and restoring the U2000 network configuration data by using the script files

1. Exports the configuration data in the U2000 to a txt file that is similar to the MML format. This is done to save data. You can directly understand the configuration contents of the txt file. 2. Backs up only some of the data, including the basic configuration data, port naming data and user-defined data. 3. The processing speed is slow and the backup file is very small.

This method is usually used to upgrade the U2000.



Databases used by U2000 NMS and LCT

All the operations about backup and restoration are implemented via backup server

Precondition: backup server and master server must be installed in the same computer Procedure: sends out backup or restore commands by SQL language, the backup server executes data input or output of disk after receiving the commands



P-32

Back up is a method used to store important data to prevent the damage of the original data. You can back up network configuration data, alarm data and performance data.

Dump is a method used to store the log information in databases as operating system files in text format, to clear database space. The dumped objects are various types of logs, including alarm events, abnormal events, operation logs and different types of performance events.

Case 5


Network element (NE) managers of some devices at the U2000 NM client are opened, appear in gray screen or abnormal display.

Cause Analysis

For the NE managers of some devices (such as PTN series, RTN series, NG WDM series, and SLM 3160) incorrect browser settings may cause abnormal display.

Case 6


On the U2000 NM, certain NEs are logged in and out frequently.

Cause Analysis

1. The number of NEs exceeds the NM management capability.

2. Insufficient disk space

Handling Process

1. Check whether the number of NEs is within the NMS management capability. Refer to the performance indexes indicated in iManager U2000 Description.

2. Check whether the disk space usage on the server exceeds 80%. If yes, free up the disk. Backup and delete related files to free up disk space.

Case 7


An NM fails to communicate with a NE. The NE icon on the NM is grayed out. In this case, an NE_COMMU_BREAK alarm is usually sent.

Cause Analysis

1. Incorrect communication parameters on the NMS or NEs.

2. Data Communication Network (DCN) failure between the NMS and NEs.

3. Mutual interference between embedded Control Channel (ECC) of subnetworks.

5. Too many non-gateway NEs carried by the gateway NEs.

6. ECC error codes.

7. Conflicts between NE users.

Case 1


A U2000 NMS is running on a workstation, status is normal, one day, the workstation is powered off abnormally, restart it, and input ”fsck y” , but the OS can’t be booted from hard disk.

Cause Analysis

The system is shut down abnormally, may be damaged the system files, in rebooting procedure, the OS can’t switch to the CDE interface, generally speaking, ”fsck -y” can repair the common errors, but if the kernel is damaged or OS boot parameters are error, ”fsck -y” can’t repair them.


Page 26

Case 1

Handling Process 1. Power on the workstation, press “STOP+A”, switch to OK interface 2. Put the Solaris installation CD into CD-ROM 3. Input “#boot cdrom -s” ,boot system from CD-ROM 4. Run “fsck –y ” and restart workstation again, but the fault still exists. 5. Switch to OK interface again, input “#df -k ” ,check whether the information of slices are correct (referring to the installation record ),then find information of slices are wrong.

Case 1

Handling Process 6、Execute format command to repair the slices table, as follows: # format Searching for disks...done …… Specify disk (enter its number): 0 selecting c0t0d0

…… 7、（Restore slice information） format> label Ready to label disk, continue? y（confirm） format> quit

Restart the workstation, ensure whether the fault is solved . 8、If the fault still exits, and the hard disk has the abnormal sound, try to replace the hard disk. Copyright © 2010 Huawei Technologies Co., Ltd. All rights reserved.

Case 2


When U2000 is upgraded, finish all the operation, then restart the OS, the operator can’t login JDE desktop with user nmsuser, only can use user name: root, password: rootkit to login.

Case 3


One day, a workstation with U2000 is restarted, re-login again, but fail to start server.

Cause Analysis

About the problem of starting server , the reader can consider it in three aspect---database is running or not, database number of user connections, environment variable.


Page 30

Case 3

Handling Process

1. Judge whether database is running;

2. Check the number of devices;

3. Check the environment variable, ensure the value of IMAP is the path of installation.


Page 31

Case 4


Because of requirement , the operator modify the IP of workstation manually, then start U2000, but he can’t start U2000, query the Sybase running status ,the database can not be started(U2000 software and Sybase are installed on the same workstation).

Cause Analysis

When modify the IP of workstation, not only modify host IP, but also need to modify database IP, otherwise database can not run.

Common Troubleshooting List

AppService abnormality

Data replication abnormality

Recovery from dual-active status

The primary node failure recovery


Page 34

Case 1 AppService abnormality If AppService stopped abnormally, the VCS will try to restart them. If restarting fails, under the rules the system will switch to the secondary node. The recovery strategies are as follows:

Clear fault of AppService on the primary and secondary nodes.

Temporarily freeze AppService on the primary and secondary nodes.

Troubleshoot the system as single node until the failure is removed.

Unfreeze AppService on the primary and secondary nodes.

Make AppService online on the primary node.


Page 35

Case 2 Data replication abnormality (RVG resource abnormality) Run the following commands:

# vxprint –v # vradmin -g datadg repstatus datarvg And the status of the data volume is not ACTIVE or ENABLED, the status of datarvg and datarlk is RECOVER, That means data replication is abnormal.


Page 36

Case 3

Dual-Active Recovery When the network between the primary and secondary nodes is interrupted more than 10 minutes, the secondary node will take over the server. Then the HA system is running in a dual-active status that the primary and secondary nodes are both active servers. In the case of dual-active, the U2000 server processes are all running on both primary and secondary nodes. After the connection recovered from the fault, the system is running in a healing status. Healing status checking: #vradmin -g datadg repstatus datarvg Config Errors: 129.9.1.1: Primary-Primary configuration


Page 37

Case 4

The primary node failure recovery

Recover the primary node. Reinstall the primary node if it is necessary.

Run the following command to forcibly disable the VCS on the primary and secondary nodes. # hastop -all -force

Use the full synchronization method to recover the system.

Restart the primary and secondary nodes after the data replication is complete.

Set the AppService online on the active server.
