9032277-04 Software Superseded by CS3/MMS3
5-93
Patches Issued Since the CS2/MMS2 Release
for the connected devices. When the device is shut off the contact
closure is noted by the Sentinel and a trap is sent. The trap is mapped
to an event that creates an alarm. The trap represents a Telcom
device being turned on. Before the alarm is cleared, the Telcom device
unexpectedly switches off which sends another trap to Spectrum.
Since the Varbind data is the same as the first trap and an alarm is
still active, the VNM filters the alarm and it is not seen by the user.
The alarm system has always favored minimizing the number of
alarms generated. In many cases a duplicate symptom may be
generated and the user doesn't want to see duplicate traps. When
SPECTRUM receives a trap with the same OID it has always
considered it a duplicate symptom and doesn't create a separate
alarm.
The resolution is to create a "U" flag in the EventDisp syntax so that
anyone can specify that a separate alarm be created for each
occurrence of an event. A checkbox is added for the new "U" flag in the
Advanced section of the Event Configure Message dialog. The
"Primary and Secondary" button in the AlarmManager's View -->
Filter --> State view will allow the user to see all the unique alarms
listed.

The problem is that SPECTRUM is not resolving certain models (ie.
Cat5000,5500,1200, etc.) down to the port level through
AutoDiscovery and therefore devices go GRAY vs. RED when the
device goes down. For example, if a Cisco router connected to 6 WA-
Link and 2 IPClassB containers goes down then all the devices in the
view will go GRAY. A red fault isolation alarm will be created, but the
user is unable to determine which devices are associated with the
fault. The device should display a RED alarm so that the user can get
an alarm on the device. In a case where a user is running multiple
servers and 10,000+ devices, the normal workarounds (i.e connecting
the other end of the router then Fault Isolation will work) are not
feasible due to numbers of devices and servers
The resolution is to alter SPECTRUM so that Device Fault Isolation
can now recognize the situation where a device connected to only
Fanouts or itself can go down and the device will go RED instead of
GRAY.
