Cisco WAN Manager Network Management

StrataSphere combines embedded management intelligence distributed throughout the network elements (for fast implementation) along with centrally located NMS workstation advanced system applications and tools to provide integrated fault, performance, and configuration management functions unique to cell-based networks. StrataSphere includes the following applications:

Cisco WAN Manager (formerly StrataView Plus)

: A single unified management platform utilizing HP OpenView^® to manage BPX, IPX, IGX, FastPAD, ESP, and INS devices.

StrataSphere BILLder

: Monitors traffic flow over a network and captures data per standard or customized billing periods and formats.

StrataSphere Modeler

: Network modeling tool used for preliminary design of new networks and for analysis and modification studies of existing networks.

StrataSphere Adaptor

: Exports network modeling information to external third party modeling systems.

SNMP Service Agent

: A service agent that provides an interface for automated provisioning and fault management to customers or Operations Support Systems (OSS).

This chapter discusses the role of Cisco WAN Manager in performing network management. For further information on network management, refer to the Cisco WAN Manager Operations publication.

Cisco WAN Manager

Cisco WAN Manager is a single unified management platform utilizing HP OpenView^® to manage BPX, IPX, IGX, FastPAD, ESP, and INS devices. It provides a standards based multi-protocol management architecture. Regardless of the size or configuration of your network, Cisco WAN Manager collects extensive service statistics, tracks resource performance, and provides powerful remote diagnostic and control functions for WAN maintenance. Refer to the Cisco WAN Manager Operations publication for details.

On-line help screens, graphical displays, and easy command line mnemonics make Cisco WAN Manager a user-friendly system. A large amount of hard disk storage is provided to allow accumulating time of day statistics on many network parameters simultaneously. The data is accumulated by the node's controller card and transmitted to the Cisco WAN Manager workstation where it is stored, processed, and displayed on a large color monitor.

Cisco WAN Manager connects to the network over an Ethernet LAN connection. With Ethernet, Cisco WAN Manager connectivity to remote nodes can be established via frame relay over TCP/IP to the LAN connector on the local node, or via inband ILMI. Also, Cisco WAN Manager provides in-band management of network elements via SNMP agents and MIBs embedded in each node and Interface Shelf.

Each node contains an embedded SNMP agent interface. This agent allows a user to manage a StrataCom network or sub-network from any SNMP-based integrated network management system (INMS).

Network Topology

A map of the network is generated at system installation to graphically display all nodes, trunks, circuit lines, and access devices in the network. Various colors are used to indicate the status of each network item. An operator can zoom in to display specific network details while a small overview map continues to be displayed as a locator.

Network Performance

Cisco WAN Manager has powerful statistics gathering capability. From data gathered throughout the network, you can quickly view the operational integrity and deployment of installed network devices and communication media by activating and invoking statistics displays.

Statistics are collected and temporarily stored by each node in the network and released to Cisco WAN Manager when you enable polling, and in accordance with your configuration for specific information within reports. Cisco WAN Manager then stores statistics in a relational database; you retrieve and view these statistics by invoking a statistics display window from the Cisco WAN Manager GUI.

Equipment Management

The Cisco WAN Manager Equipment Manager provides the ability to perform equipment management functions such as adding lines and ports on a Cisco MGX 8220 edge concentrator shelf.

Connection Management

The Cisco WAN Manager Connection Manager provides the ability to perform connection provisioning such as adding, configuring, and deleting frame relay, ATM, and frame relay to ATM interworking connections

Alarm Reporting/Event Log

Cisco WAN Manager, in addition to providing network management capabilities, displays major and minor alarm status on its topology screen for all nodes in a network. It also provides an event log with configurable filtering of the log events by node name, start time, end time, alarm type, and user specified search string.

Software Updates

System software and software updates are supplied by StrataCom on magnetic tape or floppy disk. The system software files are then loaded onto the Cisco WAN Manager workstation where they can be downloaded to a buffer memory in each node in the network in a background mode without disturbing network operation. When the loading is complete for all nodes, a command can be issued to switch all nodes over to the new software. The previous software is preserved and can be recalled at any time.

Additionally, all configuration files for the network can be obtained from the network and stored on the Cisco WAN Manager workstation for backup purposes. In the event of a system update or a node failure, the configuration files can be downloaded to one or all nodes for immediate system restoration.
