2 In the variable field, select a variable for the alarm from the list and a port (or
other ID) on which you want to set an alarm (Figure 119).
Figure 119 Alarm variable list
Alarm variables are in three formats, depending on the type:
• A chassis alarm ends in .x where the x index is hard-coded. No further
information is required.
• A card, spanning tree group (STG) or EtherStat alarm ends with a dot (.).
You must enter a card number, STG ID, IP address, or EtherStat
information.
• A port alarm ends with no dot or index and requires using the port
shortcut menu. An example of a port alarm would be ifInOctets (interface
incoming octet count).
For this example, select Bridge > dot1dStpTopChanges.0 from the
variable list. (A list of variable definitions is located in Appendix B,
“RMON alarm variables.”) This example is a chassis alarm, indicated by
the “.0” in the variable.
3 For this example, select a rising value of 4 and a falling value of 0.
4 Leave the remaining fields at their default values, including a sample type of
Delta.
