Event Types for Alarms
EPICenter Events
An EPICenter event is generated by the EPICenter server based on the results of its periodic polling. In
some cases, an EPICenter event may result from the same condition that could generate an SNMP or
other trap. An EPICenter event has the advantage that it guarantees that the condition will be detected
(by polling) even if the corresponding trap is missed.
Table 26: EPICenter Events, Detected Through Polling
Event Definition
Configuration Upload Failed The EPICenter server generates this event when it fails to upload
configuration information from a device. This event occurs ONLY when the
upload is attempted from EPICenter, not if it was attempted from Telnet,
ExtremeWare Vista or any other method.
Configuration Upload OK The EPICenter server generates this event when it successfully uploads
configuration from a device. This event occurs ONLY when the upload is
done from EPICenter, not from Telnet, ExtremeWare Vista or any other
method.
Device Policy Configuration The EPICenter server generates this event when it encounters a problem
configuring policies on a device using ACL and QoS.
Device Reboot The EPICenter server generates this event for a device when it detects a
device reboot (cold start or warm start). Unlike the cold start or warm start
SNMP trap, EPICenter generates this event by polling the device.
Device Warning from EPICenter For Extreme Networks devices only. The EPICenter server generates this
event in one of two situations:
• If the server detects and infinite loop while walking the device’s SNMP
MIB (may occur with ExtremeWare 4.1.19b2)
• If the device has a bad serial number reported through SNMP (may
occur with ExtremeWare 6.2.1 on the BlackDiamond 6816).
Fan Failed For Extreme Networks devices only. The EPICenter server generates this
event for an Extreme device when it detects, via polling, a transition from
fan OK to fan failed condition on the device. Unlike the SNMP Fan Failed
trap event, this event is generated only once, based on a state transition.
As an alternative, you can detect a Fan Failed condition by using the SNMP
Fan Failed trap, which will be generated every 30 seconds until the
condition is corrected.
Overheat For Extreme Networks devices only. The EPICenter server generates this
event for an Extreme device when it detects a transition from normal
temperature to overheat condition on the device. Unlike the SNMP overheat
trap event, this event is based on a state transition, and will be generated
only once. As an alternative, you can detect an Overheat condition by using
the SNMP Overheat trap, which will be generated every 30 seconds until
the condition is corrected.
Power Supply Failed For Extreme Networks devices only. The EPICenter server generates this
event if the device reports a power supply failure.
SNMP Unreachable The EPICenter server generates this event when it fails to communicate
with a device following a previously successful communication. In other
words, this event is generated when the state of communication with the
device transitions from reachable to unreachable.
SNMP Reachable The EPICenter server generates this event when the state of
communication with the device transitions from unreachable to reachable.
Syslog Flood The EPICenter server generates this event if the server receives syslog
messages at a rate that exceeds the user-defined limit set in the
Administration applet via the Scalability Properties. See “Server Properties
Administration” on page 363 in Chapter 16, , for more information.
