Understanding Network Management Implementation on the QFabric System

This topic describes network management features on the QFabric system that are implemented differently than on other devices running Junos OS.

The following network management features are supported on the QFabric system:

  • System log messages—The QFabric system monitors events that occur on its component devices, distributes system log messages about those events to all external system log message servers (hosts) that are configured, and archives the messages. Component devices include Node devices, Interconnect devices, Director devices, and the Virtual Chassis. You configure system log messages at the [edit system syslog] hierarchy level. Use the show log filename operational mode command to view messages.

  • Simple Network Management Protocol (SNMP) Version 1 (v1) and v2c—SNMP monitors network devices from a central location. The SNMP implementation on the QFabric system supports the basic SNMP architecture of Junos OS with some limitations, including a reduced set of MIB objects, read-only access for SNMP communities, and limited support for SNMP requests. You configure SNMP at the [edit snmp] hierarchy level. Only the show snmp statistics operational mode command is supported, but you can issue SNMP requests using external SNMP client applications.

  • Advanced Insight Solutions (AIS)—AIS provides tools and processes to automate the delivery of support services for the QFabric system. AIS components include Advanced Insight Scripts (AI-Scripts) and Advanced Insight Manager (AIM). You install AI-Scripts using the request system scripts add operational mode command. However, the jais-activate-scripts.slax file used during installation is preconfigured for the QFabric system and cannot be changed.
