The Alarm probe attempts to prevent a flood of alarms from being generated by fluctuating 
values. It does so by continuously comparing the upper and lower limits. What this means is 
that the first time either an upper or lower limit is exceeded, an alarm will be generated. 
However, if the variable moves back inside the limit, then out again, another alarm will not 
be generated unless the opposite limit is exceeded. For example, consider a situation where 
an upper limit of 75 and a lower limit of 25 is set. The variable goes to 76. An alarm is gener-
ated. If it drops to 74 then goes back up to 76, no alarm will be generated. Only when the 
variable drops below 25 will another alarm be generated. If it goes back up to 76 then 
another alarm will be generated, etc. This procedure prevents a flood of alarms from being 
generated if the value fluctuates between 74 and 76.

The 

 command is used to monitor, activate, and inactivate existing probes (remember, 

you cannot create probes in the switch’s 

UI

). You can do three things with the command:

1. View all the current probes.

2. View a specific probe.

3. Activate or inactivate a History or Alarm Probe. (You can only do this with the “admin” 

login.)

The 

 command has three optional parameters. The format is:

where:

 - activates an existing probe

 - inactivates an existing probe

 - is the entry number of the probe to view

If you enter the 

 command without parameters, it displays all the current probes. 

The entry number in the list of probes (1-16).

The slot port number (interface) that this probe is monitoring.

Ethernet, History, or Alarm.

Creating, Active, or Inactive.
