DECpacketprobe 900RR User's Information

This document is the "User's Information" manual for the DECpacketprobe 900RR, a network management agent module manufactured by Digital Equipment Corporation, published in July 1994.

Intended for experienced network managers, the manual provides comprehensive guidance on how to install, configure, use, and troubleshoot the DECpacketprobe 900RR. The device is designed to monitor and analyze traffic on IEEE 802.5 (Token Ring) networks and can be deployed either as a standalone unit or integrated into a DEChub 900 Multiswitch backplane (supporting hot-swapping).

Key areas covered in the manual include:

• Product Overview: Details the features, description, operational principles (gathering statistical information and capturing network traffic), and supported industry standards, including the Remote Network Monitoring Information Base (RMON-MIB) (RFC 1271) and its Token Ring extension (RFC 1513), and Simple Network Management Protocol (SNMP). It also describes LEDs, connectors, and community strings.
• Installation and Configuration: Provides step-by-step instructions for standalone (tabletop or wallmount) and backplane installations, power-up procedures, and configuring essential parameters like IP address, net mask, gateway address, and community strings via a console session. It also covers Bootp and Serial Line Internet Protocol (SLIP) configurations.
• Problem Solving: Offers insights into factors affecting performance and provides troubleshooting tables for common issues, both for standalone units and those in a DEChub 900 backplane.
• RMON-MIB Reference: A detailed section describing the various RMON-MIB groups implemented by the device, such as Statistics, History, Alarm, Host, Host Top N, Matrix, Filter, Packet Capture, Event, and specific Token Ring groups, explaining their data objects and functions for network diagnostics.
• Specifications and Parts: Includes physical dimensions, environmental and electrical specifications, console connector pin-out, and a list of replacement parts.
