Introduction to SPMA for the SEHI100TX-22

Your SPECTRUM Portable Management Application (SPMA) for the SEHI100TX-22 consists of a number of different applications, each of which provides a portion of the overall management functionality. Each of these applications can be accessed from the icon menu (if you are using a management platform) and from the command line (if you are running in stand-alone mode); in addition, several applications can also be accessed from within the Hub View, a graphical display of the SEHI and its ports.

The SEHI UserÕs Guide describes how to use many of the applications included with the module; note that the instructions provided in this guide apply to the SEHI100TX regardless of the operating system or management platform you are using. Instructions for launching each individual function from the command line (stand-alone mode) are also included in each chapter.

Following is a description of the applications described in this guide; while we provide as much background information as we can, we do assume that youÕre familiar with Ethernet networks and general network management concepts:

¥Chapter 1, Introduction to SPMA for the SEHI100TX-22, describes the SEHI 100 TX-22 UserÕs Guide and the conventions used in this and other SPMA manuals, explains where to Þnd information about the SEHI100TX, and tells you how to contact Cabletron Systems Global Call Center.

¥Chapter 2, Using the SEHI100TX Hub View, describes the visual display of the Hub and explains how to use the mouse within the Hub View. The operation of some basic functions available only from within the Hub View (changing the Hub View display, opening menus and windows, enabling and disabling ports, checking device and port status, and so on) are also described.

¥Chapter 3, Link/Seg Traps, describes how to conÞgure link and segmentation traps to suit your management needs. You can access the Link/Seg Traps application from the icon menu, the Hub View, or the command line.

¥Chapter 4, Redundancy, describes how to conÞgure redundant circuits to keep your network connections up and running in the event of a single portÕs failure. You can access the Redundancy application from the icon menu, the Hub View, or the command line.

¥Appendix A, SEHI100TX MIB Components, lists the IETF MIBs supported by the SEHI100TX, and describes their arrangement in a series of MIB components. A description of the objects controlled by each component is also included.
