Chapter 21: RMON Configuration Guide
288 DIGITAL GIGAswitch/Router User Reference Manual
The following examples configure the GSR to create an event when a module is hot
swapped into the chassis or any new IP interface is configured. The managed object
ifTableLastChanged from RFC 2233) has an object identifier (OID) of 1.3.6.1.2.1.31.1.5.0
and the GSR will poll this OID every 5 minutes (300 seconds).
The command line below is an example of an RMON Event group configuration with the
following attributes:
• Index number 15 to identify this entry in the Event control table.
• The event is both logged in the Event table and an SNMP trap generated with the
community string “public”.
• Event owner is “help desk”.
The command line below is an example of an RMON Alarm group configuration with the
following attributes:
• Index number 20 to identify this entry in the Alarm control table.
• The OID 1.3.6.1.2.1.31.1.5.0 identifies the attribute to be monitored.
• Samples taken at 300 second (5 minute) intervals.
• A “Startup” alarm generation condition instructing the GSR to generate an alarm if the
sample is greater than or equal to the rising threshold or less than or equal to the falling
threshold.
• Compare value at time of sampling (absolute value) to the specified thresholds.
• Rising and falling threshold values are 1.
• Rising and falling event index values are 15, which will trigger the previously-
configured Event.
