About the Network Manager
The Network Manager is a simple-to-use network management system for Cisco Unified Videoconferencing deployments.
Designed with the network administrator in mind, the Network Manager provides a unified interface for managing all the devices (elements) in your video conferencing network, including:
–Cisco Unified Videoconferencing MCUs
–Cisco IOS H.323 Gatekeeper
–Cisco Unified Videoconferencing Gateways
•Third-party elements and endpoints:
–Polycom, Sony endpoints
The Network Manager communicates with Cisco elements using a variety of industry-standard protocols, such as SNMP, XML, Telnet and FTP.
Note Ports supporting these protocols must be available in each element in order to be managed by the Network Manager.
What the Network Manager Provides
The Network Manager is a fully compliant network management system that provides network-wide functionality for Cisco elements.

Viewing Network Status
The Network Manager provides network administrators with the most critical network status information at a glance, including:
•Element information—Total number of elements, the number of faulty elements and the number of elements that are offline.
•Call information—Total number of calls in the network, the number of point-to-point calls and the number of conferences.
•Bandwidth information—Inter-zone bandwidth usage.
•B-channel usage information.
All network status information is updated in real time by the Network Manager database.
Viewing Calls and Conferences
The Network Manager provides network administrators with a view of all calls and conferences currently taking place over the network.
One-select control allows the network administrator to view call details or to access the source or destination gatekeeper element manager per call, and to link to the MCU Conference Control interface to assume full control of any conference in the list.
With these views, administrators can quickly determine:
•Call source and destination alias
•Call source and destination gatekeeper
•Call allocated resources
•The MCU controlling the conference
•Conference video and bandwidth settings.
•Number of participants—including the current number, the number reserved and the number of local participants.
The Network Manager uses an automatic detection mechanism for discovering the Cisco elements present on the network. This information is saved to the Network Manager database and is used to create the various network views available using the Network Manager interface. Auto-detect can be run at regular intervals and whenever the server is restarted. Auto-detect can also be manually initiated at any time.
Note The access field definitions for SNMP communities and Telnet must correspond with the settings configured in the selected element in order to retrieve the information from the element. If these fields are not configured correctly, the required information cannot be displayed.
Configuring Basic Elements
The Network Manager provides network administrators with the ability to view and edit the most commonly used configuration parameters of various elements in the network, such as MCUs, gatekeepers, gateways, and Polycom endpoints.
Configuring an MCU
Network administrators can configure the following MCU parameters, using the Network Manager:
•MCU type (such as MCU or MP Only)
Configuring a Gatekeeper
Using the Network Manager, network administrators can configure the following Gatekeeper parameters:
•LRQ hop count
Configuring a Gateway
Using the Network Manager, network administrators can configure the following gateway parameters:
•Gatekeeper IP address
Configuring a Polycom Endpoint
Using the Network Manager, network administrators can configure the following Polycom endpoint parameters:
•Endpoint IP address
•Gatekeeper IP address
•Endpoint alias name and E.164 number
Viewing Alarms and Events
The Network Manager provides network administrators with a list of the alarms currently active in any of the elements in the network. The list is constantly updated by the system, ensuring that any problems are located without delay. One-select access from any alarm directly to the administration interface of the device ensures that problems can be investigated and dealt with immediately.
In addition, the Network Manager provides a list of all events that have taken place in the network. This list can be filtered by the network administrator, as required.
Connecting to Element Managers
The Network Manager provides one-select access to the administration interfaces (element managers) of all the elements in the network, regardless of type, without the need to sign in individually to each element. This gives network administrators the ability to perform a full range of management and configuration procedures on individual elements. Links to element managers can be found throughout the Network Manager interface, including the Alarm and Event views, the Conferences view and the various network views.
Connecting to Terminal Managers
In addition to providing one-select access to element managers, the Network Tree view of the Network Manager also provides one-select access to the Web-based management systems of some common endpoints registered to the network.
Managing a Centralized Log
The Network Manager provides centralized log management at both the network and element type levels. Using the Settings View, network administrators can define the size of the network log file, as well as the number of backups to maintain and the level of activity detail to include in the log. In addition, the Network Manager can be used to keep logs for those elements types, such as MCU elements and gateways, that do not maintain log files of their own.
Viewing Multiple Networks
The Network Manager provides network administrators with multiple options for viewing the elements in the network, including a Network Tree view with elements arranged in a tree structure according to zone, a Network Table view that displays a single, unified list of all network elements, as well as a Network Map view that displays elements and network status information in a graphic, multi-layered format.
The Network Tree view features a default view based on the zones in the IP conferencing network. However, the Network Manager also enables network administrators to create custom views. By creating folders and placing elements into them, administrators can view the network in whatever arrangement works best, such as dividing the network according to location. The views created in the Network Tree view can also be displayed in graphic format in the Network Map view.
Configuring Offline Elements
The Network Manager can hold configuration details for offline elements and apply settings as each element goes online. Both added elements and existing elements can be configured to allow offline configuration.
Defining Network Subsets
The Network Manager enables administrators to define subsets of the network and restrict users with specific profiles to control certain network areas. Administrators can configure the network subsets using criteria to include or exclude certain zones and element types.
Supporting Cisco IOS H.323 Gatekeeper
The Network Manager provides extensive monitoring, configuration and management capabilities of the Cisco IOS H.323 Gatekeeper including local and remote zone setup, bandwidth policies, prefixes, logs, debugging and Telnet commands.
Dragging and Dropping
The Network Manager provides Network Tree drag and drop functionality for convenient element hierarchy management. Element addressing details are automatically updated in the tables of related elements. This feature can be used during offline configuration.
The Network Manager supports a comprehensive calls view detailing endpoint information, source and destination gatekeepers, bandwidth settings and call disconnection capabilities.
