DECpacketprobe 90 User's Information

This document is the User's Information manual for the DECpacketprobe 90, published in August 1993 by Digital Equipment Corporation.

It serves as a comprehensive guide for experienced network managers on how to install, configure, use, and troubleshoot the DECpacketprobe 90 agent module. The DECpacketprobe 90 is designed for IEEE 802.3 CSMA/CD networks, acting as a network management agent that implements the Ethernet Remote Network Monitoring Information Base (RMON-MIB) as defined in RFC 1271. It supports Simple Network Management Protocol (SNMP) for direct management and can be deployed either as a standalone unit with its own power supply or integrated into a DEChub 90 or DEChub 900 Ethernet backplane.

Key topics covered include:

• Product Overview: Details the module's features, LEDs, and connectors.
• Installation and Configuration: Provides instructions for tabletop, wall-mount, and backplane installation, initial console-based configuration (IP address, net mask, gateway), and power-up/reset procedures.
• Problem Solving: Offers guidance on performance considerations and troubleshooting for both standalone and backplane installations.
• RMON-MIB Reference: A significant portion of the manual describes the RMON-MIB in detail, including an overview of SNMP, managed objects, remote network monitoring goals, resource sharing, and specific parameters for its various groups (e.g., Statistics, History, Alarm, Host, Host Top N, Matrix, Filter, Packet Capture, and Event groups).
• Appendices: Contain technical specifications (dimensions, environmental, electrical, console pin-out) and ordering information for parts and related documentation.
