Data Sheet

CiscoWorks Blue Internetwork Status Monitor for System/390 Release 3.0

CiscoWorks Blue Internetwork Status Monitor for System/390 provides management and visibility of Cisco devices from the mainframe. Cisco has provided mainframe management of routers since 1996, with the first two releases of the CiscoWorks Blue Native Service Point solution. Now, renamed as Internetwork Status Monitor, Release 3.0 of Native Service Point continues to enhance this management capability. Powerful features, including the new Status Summary display (see Figure 1), focal point management, TACACS+ security, and enhanced management of Channel Interface Processors (CIPs) and Channel Port Adapters (CPAs) provide mainframe operators with full visibility of Cisco routers, interfaces, and mainframe channel connections from a single mainframe console. By enhancing IBM's Tivoli NetView for OS/390 (NetView) and Sterling Software's SOLVE:Netmaster management platforms, Internetwork Status Monitor Release 3.0 leverages investments in mainframe network and systems management and provides a reliable, scalable solution for managing Cisco devices.

Investment Protection

Internetwork Status Monitor gives the data center visibility into the Cisco network while protecting investments in mainframe software and management skills. Internetwork Status Monitor eliminates the need for TCP/IP on the host, as well as the need to purchase UNIX- or Windows-based software for basic router management. Because Internetwork Status Monitor uses many of the Tivoli NetView for OS/390 and SOLVE:Netmaster functions to deliver router management, no retraining or Simple Network Management Protocol (SNMP) knowledge is required. Familiar operator consoles with common function keys, help panels, event displays, and network logs help traditional MVS network operators ease their way into distributed network management.

Year 2000 Compliance

Internetwork Status Monitor Release 3.0 complies with Year 2000 requirements.

Proactive Network Management

Internetwork Status Monitor logs a variety of key data for historical and trend analysis, allowing network administrators to proactively manage the network. This data includes:

  • Router and interface statistics

  • Interface load statistics

  • Router and interface performance monitoring

  • CIP/CPA performance monitoring

  • Configuration archiving

By collecting performance data from the network and analyzing historical trends, a network manager can often uncover and avoid problems before they occur. Alerts can be created when CPU or memory thresholds are exceeded on routers and CIPs or CPAs.

Increased Productivity and High Availability

Quick, efficient problem resolution translates into higher productivity from network operators and higher availability of your network. Internetwork Status Monitor provides an array of features that enable operators to rapidly identify, diagnose, and correct problems within the network, including:

  • Status-at-a-glance displays for routers, Cisco mainframe channel connections, and interfaces

  • Detailed status displays for quick problem diagnosis

  • Focal point management

  • Correlation of events

  • Integrated command menu for most commonly used commands

  • Command line interface

  • CIP, CPA, and downstream physical unit (DSPU) management functionality

  • Router grouping to easily facilitate operator's span of control

  • Device-specific network management vector transports (NMVTs) for managing Cisco routers

  • Routing Information Field (RIF) information displays

Quick Detection and Correction

Internetwork Status Monitor Release 3.0 displays a summary screen of all routers being managed via the service point function. Routers are color-coded to indicate status such as up, down, connect, or performance degraded (see Figure 2). Using detailed status displays, operators can quickly diagnose problems by displaying flags next to the troubled router, indicating the nature of the problem. Events forwarded to the mainframe by Cisco IOS® software are correlated with the managed routers, allowing operators to easily select the alerts that apply to a particular router.

By simply selecting a router, an operator can access a menu of commonly used commands. This capability eliminates the need for operators to learn device command syntax. A command line interface allows operators to issue commands that are usually issued to the router via Telnet, thus making all router console functionality available to authorized mainframe operators. Commands that are typically used to diagnose CIP, CPA, and DSPU problems are made easily accessible to network operators via a full-screen interface.

Integration with Mainframe Problem Diagnosis

The Internetwork Status Monitor Release 3.0 management software works in conjunction with the service point feature implemented in the Cisco IOS software. This feature allows native management of the router from mainframe-based applications and generates NMVTs that are specific to routers and downstream devices. The alerts created in this manner are included in Network Problem Determination Aid (NPDA) and Network Error Warning System (NEWS) displays in NetView and SOLVE:Netmaster. The NMVT alerts use standard code points and require no changes to VTAM, NetView, or SOLVE:Netmaster. Automated responses to these alerts can be created in the same manner as any other NMVT generic alert.


Internetwork Status Monitor provides an additional level of security to that provided by Tivoli NetView for OS/390 and SOLVE:Netmaster. It provides further methods for controlling access to management functions. Through easy-to-use setup panels, operators can be restricted from issuing enable-level commands and are required to provide the enable password before modifying a Cisco device. Internetwork Status Monitor is integrated with the TACACS+ security feature if TACACS+ is implemented on the device. Individual operators can be restricted to administrator-defined groups of routers, allowing segmentation of responsibility and additional security. In an Internetwork Status Monitor focal point environment, the operator's authorities are based on the operator's profile on the monitored domain.

Bringing It All Together

CiscoWorks Blue Internetwork Status Monitor combines information from the Cisco environment with the information already being gathered in NetView or SOLVE:Netmaster. It allows operators to manage combined environments from a single interface. Mainframe network management platforms are highly reliable, scalable, and feature-rich. Internetwork Status Monitor increases the value of investments in these platforms by integrating information from a Cisco network with existing tools, methods, and skills.
