2.1 Functions of the eNodeB LMTThe eNodeB LMT deploys the eNodeB and identifies and clears faults locally.

Use the LMT to operate and maintain the eNodeB in any of the following scenarios:

l When the transport link between the eNodeB and the M2000 is unavailable, use the LMTto start the eNodeB locally.

l When the eNodeB fails to communicate with the M2000, use the LMT to identify and clearfaults locally.

l When alarms are generated on the eNodeB and related boards must be replaced locally,use the LMT to identify and clear faults.

NOTE

When the eNodeB communicates with the M2000 properly, Huawei recommends that you operate andmaintain the eNodeB at the network management center (NMC). When you must obtain information fromthe M2000 for fault identification, the M2000 may fail to provide adequate information because it managesmany network elements (NEs). At this time, use the LMT to operate and maintain the eNodeB.

The LMT provides a Graphical User Interface (GUI), which helps users operate and maintainthe eNodeB on the web page. It implements the following local operation and maintenance(O&M) functions:l Running eNodeB MML commandsl Managing eNodeB alarmsl Running MML commands in batchesl Tracing messagesl Monitoring eNodeB performance in real timel Software Managementl Enabling the eNodeB to perform self-testl Maintenance

Connection Port RequirementsIf the computer installed with the LMT cannot visit NEs because of firewalls between them,ports 20, 21, and 80 must be enabled by the firewall. If the computer must visit NEs using theHypertext Transfer Protocol Secure (HTTPS), port 433 must be enabled by the firewall.

Ports 20 and 21 are used for the File Transfer Protocol (FTP). They need to be enabled in thecase of file transfer using FTP.

Port 80 is used for the Hypertext Transfer Protocol (HTTP) by default. That is, the port is usedfor a web server by default.

Port 433 is used for the HTTPS by default.

Communication Capability RequirementsThe computer installed with the LMT must support TCP/IP protocols.

The minimum effective network bandwidth for the LMT is 512 kbit/s. The recommended valueis 2 Mbit/s or larger.

NOTE

l The network bandwidth limits the web page opening speed. If the recommended effective bandwidth isprovided, the LMT runs fast. If a 512 kbit/s bandwidth is provided, all the functions can be performed butthe LMT runs slowly.

l The effective bandwidth is the bandwidth occupied by the LMT. If multiple applications compete for thebandwidth, the LMT may run slowly even if a 2 Mbit/s bandwidth is provided.

27

5.1 Basic Concepts Related to eNodeB Alarm or EventManagement

Before managing eNodeB alarms or events, you must understand basic concepts related toeNodeB alarms or events, alarm or event definition, alarm or event log, alarm or event severity,and network management (NM) alarm or event type.

5.1.1 Basic Concepts Related to Alarms or EventsThis section describes the basic concepts related to fault, event, and engineering alarms.

Fault Alarm

A fault alarm is generated when a hardware is faulty or a major function is abnormal. A faultalarm has a higher severity than an event. Based on the status of the faults, fault alarms can becategorized into active alarms and cleared alarms.

l If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is calleda cleared alarm.

l If a fault is not cleared, the status of the alarm remains active. This type of alarm is calledan active alarm.

NOTE

You can search a database for cleared alarms.

Event Alarm

An event notifies users of important information when the system is running properly. Usersneed not handle an event when it is generated.

Engineering Alarml If an NE is being installed, commissioned, upgraded, expanded, or relocated, the NE is in

the engineering state.

l The following are engineering alarms: alarms reported by physical or logical equipment inthe engineering state; alarms that are generated by the peer equipment but are associatedwith the alarms reported by the equipment in the engineering state; cleared alarmscorresponding to engineering alarms.

5.1.2 Alarm or Event LogThe alarm or event logs record detailed information about each alarm or event generated by thesystem. In this way, all alarms or events can be easily queried.

You can obtain the detailed information about eNodeB alarms or events from the alarm or eventlogs. For details about how to query the alarm or event logs, see 5.2.2 Querying Alarm or EventLogs.



28

5.1.3 Alarm SeverityThe alarm severity indicates the severity of an alarm. Based on the severity, all alarms can becategorized into four types: critical, major, minor, and warning.

Table 5-1 describes alarm severities and handling suggestions.

Table 5-1 Alarm severities and handling suggestions

Severity Definition HandlingSuggestion

Critical Service-affecting condition. Critical alarmsrequire immediate attention, and must be clearedimmediately. For example, faulty devices arerepaired or unavailable resources are restored.

Alarms must becleared immediately.Otherwise, thesystem may breakdown.

Major Degradation of service, not a complete loss ofservice. Major alarms must be cleared duringworking hours. For example, device performanceand resource performance improve.

These alarms must becleared in time.Otherwise, someimportant functionscannot beimplemented.

Minor Non-service-affecting condition. Minor alarmsmust be handled within a certain period to avoidseverer problems.

This helpsmaintenancepersonnel identifyand clear potentialproblems in time.

Warning Potential service-affecting condition. Warningalarms must be cleared as required.

You only need tolearn about theoperating status ofthe system.

5.1.4 NM Alarm TypeBased on network management (NM) standards, alarms are categorized as follows:

l Power alarm: related to the power system

l Environment alarm: related to environment of the equipment room

l Signaling alarm: related to service signaling

l Trunk alarm: related to the transport subsystem

l Hardware alarm: related to boards

l Software alarm: related to software

l Running alarm: related to system running

l Communication alarm: related to the communication system

l QoS alarm: related to QoS.



29

l Integrity violation alarm: a type of security alarm, which indicates that information maybe modified, added, or removed without permission.

l Operation violation alarm: a type of security alarm, which indicates that services areunavailable or unreachable due to incorrect operations, faults, or other reasons.

l Physical violation alarm: a type of security alarm, which indicates that physical resourcesare unavailable due to possible attacks.

l Security violation alarm: a type of security alarm, which indicates that the security serviceor security mechanism detects that the system is experiencing attacks.

l Time domain violation alarm: a type of security alarm, which indicates that unexpectedevents have occurred.

l Processing error alarm: related to other exceptions.

6.1 Overview of Message TracingThe section describes message tracing management functions and the internal process ofmessage tracing.

Functions of Message Tracing ManagementMessage tracing management traces interfaces, signaling links, UEs, and internal messages. Itapplies to routine equipment maintenance, debugging, and fault location.

Tracing functions are as follows:l Tracing messages over the S1 interfacel Tracing messages over the X2 interfacel Tracing messages over the Uu interfacel Tracing SCTP messagesl Tracing IFTS messagesl Tracing CMPv2 messagesl Tracing MAC messagesl Tracing IEEE1588 V2 messages

Internal Process of Message TracingThe internal process of message tracing involves creating a tracing task on the LMT and reportingresults to the LMT.

l Creating a tracing task on the LMT

1. After you create a tracing task on the LMT, the LMT sends a binary command to theeNodeB to create the task.

2. The eNodeB allocates an ID to the task and forwards the command to the tracingmanagement module of a specified board.

3. After receiving the command, the tracing management module records the parametersfor tracing contained in the command in the filter table and sends messages to theservice processing module.

4. The service processing module updates the local filter table based on the messagesfrom the tracing management module.

l Reporting results to the LMT

1. After receiving messages from the tracing management module, the service processingmodule verifies that the parameters in the local filter table are updated. Then, it reportsthe messages meeting filter criteria to the LMT based on the task IDs contained in themessages.

2. The LMT analyzes the messages and displays tracing results in the window.

6.9 Tracing IEEE1588 V2 MessagesThis section describes how to trace IEEE1588 V2 messages and to identify faults on IEE1588clock links.

Context

l IEEE1588 defines the Precision Time Protocol (PTP), which applies to standard Ethernet.IEEE1588 V2 is a Precision Clock Synchronization Protocol for Networked Measurementand Control Systems, which is also called PTPv2.

l IEEE1588 V2 is mainly used for time synchronization among nodes of the distributedsystems. It specifies a mechanism for all nodes to achieve time synchronization using thesame reference clock.

l The eNodeB can use the IEEE1588 V2 clock as the reference clock to achieve timesynchronization. IEEE1588 V2 transmits timestamps based on interactions betweenIEEE1588 messages so that the eNodeB achieves time synchronization. If the IEEE1588V2 clock does not function properly, the tracing for IEEE1588 V2 messages is started toview the information.



54

l If all IEEE1588 messages are selected for tracing, check the interval at which messagesare transmitted on the clock link. If IEEE1588 V2 packets are transmitted at small intervals,there are many packets. Therefore, starting the tracing affects the system performance. Youare not advised to start different tracing tasks.

When the SSL protocol is used by a browser to connect to the LMT,a Security Warning dialog box is displayed, indicating that the authority that issues thecertificate is not in the list of trusted root certification authorities.

l Currently, the LMT is visited using its IP address. The LMT does not have a domain name,and therefore the eNodeB name cannot match the LMT certificate.

Procedure

Step 1 When you attempt to log in to the LMT, the browser may display a security warning. If you seethis warning, choose Yes to continue.

11.11 How to Rectify a Failure to Log In to the LMT Due toa High Default Internet Explorer Security Level

In Windows Server 2003 or Windows Server 2008, the IE browser blocks Web programs onsites that are not in the trusted site list to improve system security. As a result, you may fail tolog in to the LMT.

Contextl According to acceptable Internet Explorer security levels, there are the following two

solutions:– If lowering the Internet Explorer security level on the Windows server is unacceptable,

you can add the LMT site to the trusted site list of the Internet Explorer using a



123

configuration startup script. The system automatically loads the script and configuresthe Internet Explorer after a user logs in.

– If lowering the Internet Explorer security level on the Windows server is acceptable,you can remove Internet Explorer Enhanced Security Configuration, a Windowscomponent.

Procedurel To set a configuration startup script, perform the following steps:

1. Create a configuration startup script.

NOTE

l The IE-unset.bat script file enables the system to automatically add a site to the trusted site listof the Internet Explorer.

l You can modify the file when required, for example, change 10.141.149.193 in reg add %uu% /v :Range REG_SZ /d "10.141.149.193" /f >nul in the script to the IP address of the networkelement to be visited.

l The Trust field in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\EscRanges\Trust can be named as required.
