Alarm Configuration

Setting Alarms at the Ring and Station levels; Alarm Types defined

Alarms work in conjunction with your network management system to let you know when certain defined thresholds have been reached. Using this tool, you define the condition that will trigger an alarm; the device monitors traffic and, when defined thresholds are reached, reports to the network management station in the form of a trap. You can set alarms at the Ring and Station levels; the effect of an alarm depends on the parameters you have set via your management platform.

NOTE

SPMA does not accept the trap messages; that task is left to your network management system. (See the appropriate network management system documentation for details about viewing trap messages.) When this application is used in stand-alone mode, traps will either be ignored when they return to the workstation from which you are running SPMA for the TRMMIM, or they will turn up at another management workstation which has been configured to accept traps. Note also that, regardless of the configuration performed using this application, NO traps will be sent by the device unless its trap table has been properly configured; see the TRMMIM hardware manual and/or the Trap Table chapter in the SPMA Tools Guide for more information.

At the Ring level, you can set alarm thresholds for the cumulative totals of ring purges, active monitor participant errors, token errors, claim token errors, lost frames, and frame counts detected on the ring. At the Station level, you can set alarm thresholds for each individual station’s count of line, internal, burst, AC, and congestion errors.
