Patches Issued Since the CS2/MMS2 Release

CsIHRollPL will transmit the SPECTRUM event from the router

device model to the appropriate port instance if the information is

contained in the trap. This inference handler is attached at the

GenSnmpRouter model type. Therefore, it only seems to be running

for router model types at the moment. The CsIHPrtAlrm IH will

trigger on the link event sent from CsIHRollPL (or any other IH for

that matter) and create a RED alarm for linkDown traps or disassert

any previous alarm for a linkUp trap.

The resolution is to create a new boolean attribute that was added to

the Gen_IF_Port model type. This allows that some ports of a

particular device can be speciﬁed to alarm on receipt of the trap while

others will not. Also, a particular port (e.g. ISDN) can be set not to

alarm by default.

The problem is that the Unmanaged Trap Handling set by the user in

the VNM Control View will be overwritten by the default value if the

SpectroSERVER is shutdown and restarted. For example, if the

widget is set to "Disabled" and then the SpectroSERVER is shut down

and restarted events WILL be created as a result of the traps from

unmodeled devices. The normal behavior should be that events will

not be created as long as the widget is set to "Disabled". It is

important to note that events are not created until the

SpectroSERVER is shut down and restarted.

The resolution is to modify the inference handler to read the VNM

model's version of DisabledManagedTraps versus the default value

upon SpectroSERVER start up.

The problem is that SIP (ifType 31) interfaces of Cisco Routers were

being modeled by SPECTRUM as Gen_IF_Ports versus

Serial_IF_Ports. This was causing inaccurate Performance data to be

generated for the customer.

The resolution is to modify SPECTRUM code so that SIP (ifType 31)

interfaces would be modeled with a Serial_IF_Ports model type.

The ﬁrst problem is that linkDown traps dispense event 0x220002

which CsIHPortLinkTrap::trig_event() asserts a RED alarm on. For a
