CiscoWorks 2000: Routed WAN Management Solution
The configuration management functions enable the planning and installation of network elements and their interconnection into a network, and the activation, modification and deletion of customer services that use that network.
The performance management functions evaluate and report on the effectiveness of the network and network elements for the support of services. The focus within performance management is the collection and analysis of statistics for the call agents, media gateways, and routers. The call level statistics, traffic flows for traffic engineering, and measurements at the edge routers generate a series of specialized reports that provide an indication of the core network performance and how this impacts voice traffic.

The fault management functions enable the detection, isolation, and correction of abnormal operation of the network. Each of the individual EMSs captures fault information, and HP OpenView Network Node Manager (NNM), delivered with Cisco WAN Manager (CWM), can optionally be used with the media gateways. Fault management for the Cisco IOS devices (for example, the Cisco 7500 and 12000 series Internet routers and Catalyst switches) uses the Cisco CNS Notification Engine (CNOTE) to forward Syslog messages to operations support systems (for example, Cisco Info Centre). These routers and switches can also optionally use the HP OpenView NNM for fault management. The HP OpenView NNM, together with the Fault and Trouble Management component of the Italtel Multiservice Element Manager (MSEM), provide an overall network-wide view, or can be used to monitor subdivisions of the Cisco Multiservice Packet Network Solution (for example, core, access, media gateways, and call agent) as required.

Within the Cisco Multiservice Packet Network Solution, accounting management, to enable the use of the network services to be measured and the costs for such usage to be determined, falls within the domain of the call agent management system MSEM.
See Table 3-1 for a summary of the EMSs for the media gateways and call agents supported as part of the Cisco Multiservice Packet Network Solution.
See Table 3-2 for a summary of the EMSs that could be used with the core and access routers and switches.
Element management systems are available for each of the components of the solution. See Table 3-3 for a summary of these systems.
Management of the call agent components is provided by the Italtel-supplied MSEM applications: Service Configuration Manager (SCM), Fault and Trouble Manager (FTM), Traffic and Performance Manager (T/PM), and Billing Manager.
Management of the data core components can be provided by the Cisco 12000 Manager (C12KM), and management of the access switches and routers can be provided by CiscoWorks 2000 (CW2K) Routed WAN Management Solution, with the Resource Manager Essentials (RME) application. Note that configuration management for the switches is optional within the Cisco Multiservice Packet Network Solution because the switches have static configurations.
The C12KM and UGM are integrated within the Cisco Element Management Framework (CEMF)—the foundation element management layer of the Cisco Service Management (CSM) system. CEMF provides common interfaces and management services for the element management applications, including an easy-to-use graphical user interface that isolates the end operator from the complexities of Cisco IOS software and the Simple Network Management Protocol (SNMPS. In addition, CEMF provides a standard set of external interfaces that enable higher-level network and service management applications to be integrated and enabled.
The CWM is shipped with WAN CiscoView. This GUI-based device management software application allows you to display a graphical representation of the Cisco MGX 8230, 8250, and 8850 platforms, display configuration and performance information, and perform minor configuration and troubleshooting tasks.
The Network Browser provides a hierarchical representation of network information in a table format, based on either a physical or logical relationship among the various network elements, and the Security Manager provides controlled access to multiple users of CWM, based on the unique user ID and password.
HP OpenView NNM provides network views in an intuitive graphical format. It discovers network devices and provides a map to illustrate the structure of the network and the status of devices and segments. When a major device fails, the event correlation engine evaluates the event stream to pinpoint the root cause of the failure. Other capabilities help you prevent problems by identifying potential trouble spots before a failure occurs, allowing you to manage the network more intelligently, thus leading to increased network up-time and lower costs.
The OpenView Event Management System provides a framework for the display of alarms. OpenView identifies problems fast through an advanced event correlation engine, immediately pinpointing the root cause of network problems, while also displaying all of the contributing events for each of the alarms. Out-of-the-box correlation circuits are included for some of the most common network management problems.
Out-of-the-box reports present trends on performance, availability, inventory, and exceptions. Analysis of this historical data provides a clear picture about the devices in the network and allows you to become more proactive in managing faults.
The OpenView Alarm Browser provides a convenient central location for monitoring critical events on your network. The Alarm Browser sorts the alarms into categories and dynamically filters the alarm list (for example, by node) to make the information more useful. Alarm categories used are as follows: Error, Threshold, Status, Configuration, Application Alerts, and All. The Alarm Browser can also manage the alarm process by acknowledging that the problem causing an alarm is being addressed, deleting alarms from the list after they are resolved, and specifying additional actions that can be executed upon selected alarms.
UGM supports role-based access to its management functions, with the Access Manager allowing you to define user groups and assign users to these groups, and also support control of administrative state variables for UGM resources.
MSEM provides configuration, performance, and fault management for the Italtel iMSS-4040 and iMSS-4050 call agents, with the capability to manage up to 50 Italtel Multiservice Switching System (iMSS) call agents. MSEM interacts with the Operation and Maintenance Server (OMS) to manage the Optical Peripheral Module (OPM) and Protocol Handling Server (PHS) components of the iMSS and to perform its element and network management functions.
OMS is the operator interface to the OPM and PHS components of the exchange, allowing local and remote management through a linked Windows NT console. OMS functions include software download and start-up management, exchange upgrade management for maintenance activities such as switchover, and built-in alarm collection and troubleshooting diagnostics (checking faults for consistency and translating into diagnostic reports). OMS provides an interface to MSEM.
MSEM is the centralized system for the operation, administration, and maintenance of the iMSS call agent, providing automatic collection of billing and traffic data, alarm management (collection, filtering, correlation, and user alerting), and transmission of service provisioning and configuration data. MSEM supports exchange operations such as remote transfer and remote activation of software patches and voice announcements, date-time monitoring and synchronizing between MSEM and iMSS, transparent access to the iMSS to allow data queries and modification, and scheduling of iMSS command batch broadcasting.
The C12KM, within the CEMF, delivers a range of provisioning, configuration, fault isolation/analysis, inventory, and capacity management tools for the Cisco 12016 and 12416 Internet routers in the core of the Cisco Multiservice Packet Network Solution.
The CW2K: Routed WAN Management Solution provides applications for configuring, administering, monitoring, and troubleshooting the Cisco 7507 and 7513 routers, and the Catalyst switches in the Cisco Multiservice Packet Network Solution. The application provides visibility into network behavior, identifies performance bottlenecks and long-term performance trends, provides configuration tools to optimize bandwidth and link utilization, and receives and analyzes information collected by remote monitoring (RMON) devices.
The Cisco Multiservice Packet Network Solution uses CiscoWorks 2000 CD One, 4th Edition. This includes CiscoView, a graphical SNMP-based device management tool that provides real-time views of networked Cisco Systems devices. These views deliver a continuously updated physical picture of device configuration and performance conditions, with simultaneous views available for multiple device sessions.
The RME application provides configuration, inventory management, syslog and change reporting, and software image management for the routers and switches in the Cisco Multiservice Packet Network Solution.
RME allows you to collect the monitoring, fault, and availability information needed to track devices critical to the network uptime and application availability. RME also provides tools that you can use to rapidly and reliably deploy Cisco software images and view configurations of the routers and switches, and, together with Cisco.com service and support, automate software maintenance.
RME is based on a client/server architecture that connects multiple web-based clients to a server on the network. As the number of network devices increases, additional servers or collection points can be added to manage network growth with little impact on the client browser application. By taking advantage of the scalability inherent in the intranet architecture, RME supports multiple users anywhere on the network.
CNOTE is a high-performance fault management gateway that receives Syslog messages from IOS devices and converts them into SNMP v1 or v2c traps, which are forwarded to OSSs (for example, Cisco Info Centre) that have registered with CNOTE. During trap conversion, the CNOTE adds additional information to the traps, such as slot number and port number thus enriching the information contained in the network event messages. This added information makes it easier for OSS fault management applications to perform event deduplication and fault correlation operations.
In addition, the CNOTE gateway improves network monitoring by delivering a robust trap stream to recover nonreliable User Datagram Protocol (UDP) traps when they get lost in the network. Multiple OSS clients can register themselves with a single CNOTE gateway using category trap filters to receive different streams of events, and the gateway provides a set of user-defined trap suppression and severity overwrite rules to manage the network.
Using the CNOTE gateway as an event source, fault management systems can manage the Cisco 12000 series Internet routers, Cisco 7500 series routers, and Catalyst switches in the Cisco Multiservice Packet Network Solution. In addition, CNOTE can receive events from Route Processor Modules (RPMs).
