A-8 ExtremeWare EPICenter Software Installation and User Guide
• For a non-Extreme device, make sure you have set EPICenter as a trap receiver on the
device (see Chapter 8).
• For an RMON alarm, make sure you have RMON enabled on the device.
Problem: The “Email to:” field is greyed-out in the Actions tab of the New Alarm
Definition dialog
You need to specify an e-mail server in order to send e-mail. Click the Settings... button
next to the Email tofield to set up your mail server.
Problem: An RMON rule is defined to monitor a counter variable, and to cause an
alarm when the counter exceeds a certain value. The counter has exceeded the
threshold value but no alarm has occurred.
There are several things to check:
• MakesuretheRMONruleandthealarmdefinitionaresetupcorrectly
• If the value of the counter was already above the threshold value when you set up the
RMON rule, and you have the Sample Type set to Absolute, no alarm will ever be
generated. This because the value must fall below the Falling Threshold value before
the before another Rising Threshold trap will be sent, and this will never occur. You
should consider using the Delta Sample Type instead.
Problem: When creating an RMON rule in the RMON Rule Configuration window,
the MIB variable I want to use is missing from the list of variables displayed when I
click “Lookup...”
The MIB Variable list displays only the MIBs shipped with the EPICenter software. In
addition, within those MIBs the variable list will not display variables that are indexed by
anindexotherthan (orinadditionto) ifIndex.Youcanstillusevariablesthatdonotappear
in the Lookup... list, but you must type the complete OID into the MIB Variable field, in
numeric notation. If the variable is a table variable, you will need to append the specific
index and apply the variable to each target device, one at a time.
Problem: A program specified as an action for an alarm (in the Run Program field)
does not get executed. It includes output to the desktop among its functions.
If you are running the EPICenter server as a service, you must specifically tell it to allow
output to the desktop. To do this you must stop and restart the EPICenter server, as
follows:
