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.
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.
To access the main alarm window
from the icon:
1. Click on the appropriate device icon to display the Icon menu.
2. Drag down to Alarm Configuration and release.
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.
