NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 13 of 64
As an option, NetMaster can be configured for redundancy with failover capabilities, with manual or automated database replication between main and standby NMS sites. This can be applied to achieve co-located HW redundancy as well as geographical system redundancy for disaster recovery.
Redundant NetMaster system with replication and failover
The database replication can operate as Hot Standby with duplicated active servers with automated, scheduled synchronization, or Cold Standby, where the standby server must be manually started upon failure.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 14 of 64
2.1 Application server
The application server manages the interaction of all NetMaster system components. It runs continuously in the background as a service.
The application server is initially developed for Microsoft Windows systems. It is based on JAVA/J2EE technology, hence suitable for porting to other platforms as well.
2.2 Database server
The database server stores all data used by the NetMaster system. The NetMaster management system supports database products from two different origins:
Oracle, a commercial, proprietary database SW vendor
PostgreSQL, a freeware, open-source database SW project
For more details:
Oracle databases: http://www.oracle.com/database/
PostgreSQL database: http://www.postgresql.org/
Supported database versions: please refer to the latest NetMaster System Requirements document.
2.3 Client
A client provides the user interface to the running services and the network managed by the server. Up to 20 clients can be logged on to the server simultaneously. Clients can be installed separately and are launched on demand and connected to the NetMaster application server.
Client and server are connected on a TCP/IP based LAN. Interactions between client and server are based on JAVA RMI.
A NetMaster client can be installed on Microsoft Windows or Sun Solaris platforms.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 15 of 64
2.4 Northbound interface to higher-order OSS
The NetMaster architecture supports an open interface to higher order management network systems or other business operations components.
The NetMaster SNMP agent provides an interface for any SNMP based network management system to perform fault and inventory management in networks managed by NetMaster. The agent provides topological information according to the standardized ENTITY-MIB (RFC 2737), and alarm state of the various network elements through proprietary tables and variables given in the proprietary NETMASTER-MIB. State changes are communicated to managers by means of SNMP traps.
The SNMP agent is a specialized client that logs onto the NetMaster server with a user ID and exposes a set of information through an SNMP interface. The only requirement to the user ID is that it is member of the predefined "SNMP Agent" user group, or a group with similar action permissions. This gives a very good control over the part of the network that is exposed to the High Level Manager (HLM), as the resource permissions for the SNMP agent user group can be configured in detail in the exact same way as any other user group defined in NetMaster.
The NetMaster SNMP agent is an optional feature, which requires a separate license. Inventory management is controlled by an additional license.
2.5 Communication ports
Management communication between NetMaster and a network element is based on one of the following:
SNMP over UDP/IP
HTTP over TCP/IP
Nera Q1 over TCP/IP
Nera Q1 over serial RS-232
Two different communication principles are used; polling of NE’s from NetMaster and Notifications sent from NE to NetMaster.
For specific port numbers in use for client/server and server/database communication, please refer to the latest NetMaster Installation Guide.

NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 22 of 64
3.6 Alarm workflow perspective
NetMaster alarm workflow perspective
NetMaster provides a preset perspective that helps focus on the alarm workflow. The alarms initially appear in the Active un-acknowledged view, and eventually end up in the Historical acknowledged view. The two intermediate views show whether the alarm is cleared before it was acknowledged or vice versa.
The idea of this perspective is that the operator shall be made aware of all problem situations in the managed network. The workflow focus helps choosing the appropriate actions both for intermittent problems and for more permanent issues.

For easy storage of the NE configuration settings, a utility for NE configuration file backup and restore has been provided. This enables the NetMaster operator to restore a network element to a previous used configuration, which can be useful in case of major HW changes or complete re-installation at the radio site.
A configuration backup can be created at any time, for one single NE, a domain or a complete network. The backup will be time-stamped and tagged to the actual NE before it is saved to the database.
NE configuration file management
Valid configuration files acquired from other external sources can also be added to the NetMaster configuration file management system.

5.2.8 Launch NE tools
For detailed configuration of individual NEs, NetMaster provides a function to launch a scoped NE configuration tool for a selected NE.
The Administrator configures the external tools to be associated with the various NE types and may also link various attributes obtained from the server to corresponding launch arguments on the external tool (like IP address, NE identification, authentication credentials). The configuration tool for a specific NE can then be launched from the context menu on the NE symbol in the NetMaster client.
NE configuration tools
5.3 Fault management
The NetMaster series provides functions for acquisition, storage and presentation of alarms and events from the managed network.
Typical fault management tasks include:
Alarm acquisition in the form of notification reception from NEs
Display network alarm status in many different ways
Coloring of graphical objects in the network views
Display new (un-acknowledged) alarms and old (acknowledged) alarms independently.
Propagation of the highest severity level upwards in the network display hierarchy.
Display alarm summary count
Display current alarms
Alarms acknowledging, un-acknowledging and commenting
Audible notifications upon severity level increase.
Display historical alarms; specify advanced filters/queries.
Customize alarms for selected NE types (alarm text, severity and blocking) for a selection of NEs through alarm templates.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 39 of 64
5.3.1 Network alarm status
The status of the network and network elements is displayed through a graphical object coloring scheme in the graphical views. When the network is structured into a hierarchy of administrative domains, the alarm severity colors are propagated upwards in the hierarchy.
To ensure that new events are always in focus, there are two levels of alarm coloring and propagation:
The highest un-acknowledged (new) alarm severity status is displayed in the fill area of the graphical symbol.
The highest acknowledged (old) alarm severity status is displayed as a thin frame around the graphical symbol.
The graphical symbols in the map views also display the number of alarms of the highest severity for both acknowledged and un-acknowledged alarms. The coloring scheme used for each severity level can be configured in the Preferences dialog.
Network alarm status
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 40 of 64
5.3.2 Alarm summary
The Alarm summary view shows an overview of all alarms for all managed NEs and provides a quick overview of the alarm status in the entire network.
The view displays the Severity count graph: a graphical presentation of alarms of each severity category in the entire network. The graph includes a bar for each of the categories Critical, Major, Minor, Warning, Indeterminate, and Info.
The view will only present active alarms, i.e. clearable alarms in a raised state, and not those that have been cleared. The same alarm state is presented in the Active alarms view.
Whenever an alarm is cleared on the equipment, it disappears from the Alarm summary view, but can be found in the Historical alarms view.
Alarm summary
By clicking one of the severity bars, a filtered Active alarms view containing the alarms of the selected severity level will be opened.
5.3.3 Display Active Alarms
The Active Alarms view presents active alarms for a selected scope, and allows the operator to acknowledge alarms which have been followed up.
An active alarm is a clearable alarm in the raised state (i.e. not yet cleared). Whenever an alarm is cleared, it will be removed from the table, but can still be found in a corresponding scope in the Historical alarms view.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 41 of 64
Display active alarms
Each user may select which attributes are shown in the alarms table, in which order the fields appear, and may sort the table ascending/descending on any column.
The Active alarms view contains two powerful filtering mechanisms for further drill-down within the current scope. It is possible to show or hide alarms based on their acknowledgement status, or, using an instant filtering function, showing only alarms that contain a certain textual pattern in one or more attribute.
Alarm filters
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 42 of 64
5.3.4 Display historical alarms
The Historical alarms view displays a table of all historical alarms or events for a selected scope. Historical alarms are alarms that have been raised and then cleared. The Historical alarms view also shows alarms that are non-clearable, i.e. events. Whenever an alarm appears in the Historical alarms table it will disappear from any table with the same scope in the Active alarms view.
Historical alarms
The advanced filter function in the Historical alarms view can help you when analyzing situations with errors or poor performance in your network. By studying other errors and the order they appeared for the NE, this view can help you identify and solve the "root cause problem".
To navigate quickly in a large data set, the Time slider function may be of great help. The Time slider shows a histogram of the number of alarms occurring along the time axis, and the area indicated with green color shows what time interval is currently presented in the alarm table. It is possible to expand this time interval, or to zoom in for a further detailed histogram.
It is possible to set up auto-refresh of the Historical alarms view.
The Historical alarms table may display the following fields for each alarm:

5.4 End-to-end Service Management
NetMaster provides advanced functions for End-to-end TDM and Ethernet Service Management.
5.4.1 Network Discovery
In addition to the automated discovery of NEs and general network topology, NetMaster also performs automated discovery of the connectivity in relation to services. This means that all potential service carrying connections are automatically discovered and offered as available resources for subsequent service provisioning.
5.4.2 Service Discovery
Upon connecting to an existing network, NetMaster offers automatic discovery of all services currently configured on each NE (dependent on NE capabilities). Any service that is discovered can, by operator decision, be included under NetMaster management, or left “as is”.
Once managed by NetMaster, the discovered services are covered by the same functionality as services created from NetMaster, including Service Alarms, Service State, Service Editing, general Service Displays and all reporting, statistics and historical data records.
5.4.3 Service Creation Wizard
NetMaster provides an intuitive and powerful Wizard that guides the users through the entire service provisioning workflow. Services are created by automated routing between the selected end points.
Ethernet Services can be Untagged or C-VLAN tagged.
5.4.4 Service Monitoring
Managed services are monitored for operational state (“Service State”, i.e. enabled, disabled, pending and various fault states). Alarms that are generated on the ports involved in a service are associated with the service in order to provide the alarm state of each service (“Service Alarms”).
5.5 Performance management
NetMaster provides functions for collecting, storing and displaying performance data from the network elements.
Typical performance management tasks include:
Historical performance monitoring
Supporting various types of performance data:
Analog measurement values
G.826 measurements
RMON Ethernet statistics
Displaying stored performance data in tabular and chart views
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 46 of 64

NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 50 of 64
5.5.3.1 Overview PM report
The Overview report gives a summary of performance measurements (G826 parameters) as defined with a filter. The values of each performance parameter type will be the sum of all individual measurements of that type in the time interval specified in the filter.
Two graphical charts are displayed based on these selections.
Performance overview report
Measurement types over time (x- axis: time, y-axis: measurement value)
In this graph, it is normally easy to detect which types of errors dominate the overall performance, and how these are distributed in time. Based on this, the further investigations can focus on a specific window of time.
Measurement types over source network element (x-axis: Network Elements, y-axis: measurement value)
This graph displays the occurrence of performance errors for each network element, accumulated for the selected time interval. Any network element with a high number of errors is easily spotted, and may then be subject to further investigations.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 51 of 64
5.5.3.2 Detailed PM report
The details report gives a listing of all performance measurements matching a defined filter.
Detailed performance report
All collected PM data from all network elements matching the filter is displayed in a tabular form, in which the detailed counters can be inspected. The table can be sent to printer or exported in PDF format, and also exported to file in XLS format, e.g. for further analysis and visualization.
Before printing, bear in mind that with a high number of active counters and/or selected network elements, this table can become very large.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 52 of 64
5.6 Security management
NetMaster’s security management is role-based. It is handled through group administration and user administration functions.
The Group administration view is used when creating new user groups and assigning permissions to each group. A specific group permission is assigned from the combination of the corresponding resource permissions and action permissions.
Group administration
The Resource permission part displays the domains (sub-networks) for the selected group name. Permissions can be changed by checking or un-checking the checkboxes in the Resource permissions tree. The users in a specific group can only see the domains to which the group has been granted resource permissions; all other domains will be hidden.
The Action permission defines to which areas of functionality the selected group is granted permission.
NetMaster NMS Technical Description
Ceragon Proprietary and Confidential Page 53 of 64
The individual users are defined in the User administration view and assigned to one or several groups. From this view, a user can be created, deleted, blocked or un-blocked, and the user’s password can be changed.
User administration
All user events are logged to the database and can be listed in the User audit view.
User audit view
5.7 Open SNMP Adapter
The purpose of Open SNMP Adapter is to be able to discover and manage
SNMP elements that are not fully integrated in NetMaster. These types of
elements will be called open SNMP network elements (open SNMP NEs).
The following are the main points covered in the first release of open
SNMP:
(1) Discover any SNMP equipment (SNMP version v1 and v2c)
