897.0. "HUBwatch and traps?" by WARNUT::64021::Tim_Banks (Network Mercenary) Tue Apr 12 1994 05:21

I did a demo of HUBwatch Windows 2.0 for a customer recently and got a lot of 
questions about generating alarms when for example a port on a repeater 
developed a fault - say cable fault causing the port to partition.

I can see that some of the HUB modules generate trap events, but can HUBwatch 
do anything with them?  From my experience of HUBwatch both VMS and Windows, 
it can't, and I believe you would need DECmcc or Netview to flag trap events 
to a network manager.

Am I correct in this belief?  Will HUBwatch gain that kind of functionalaity 
at some stage or are we saying to a customer you need Netview?

	Thanks

897.1Question renamed, "HubWatch and Alarms".QUIVER::GALLAGHERTue Apr 12 1994 15:0028
You're correct.  HubWatch doesn't currently support alarms.  It will in 
the next release.  (More on this later.)

The repeaters don't currently generate traps when ports are partitioned.
The repeaters support only the generic ColdStart, LinkUp, LinkDown, and
Authentication Failure traps now.  (LinkUp and LinkDown traps refer to
"Links", not "Ports".  The "Link" is a MAC over which the repeater is
managed.)

Some future repeaters will include RMON Alarms & Events.  This feature
will allow traps to be generated when ports become partitioned.

But the question really has nothing to do with traps -- the question
has to do with alarms.  Since traps are not reliable polling is necessary.
The polling Network Management Station must generate alarms when thresholds
are met or exceeded.  (This blurb is SOP for me.  Each time I answer a 
question about traps I have to reiterate that if your network management
plan relies on traps then your network management plan is broken.)

You could use DECmcc, PolyCenter Netview, or some other enterprise manager 
to set up polling for partitioned repeater ports.  Or, you could wait for
HubWatch support of "basic alarming".  HubWatch support of "basic alarming" 
is discussed in notes:

	580.3   December, 1993, and
	791     March, 1994.

p.s.  The only time we say you need Netview is when we're asked for
      generic network management capability, like MIB browsing.
