Re: 3COM Corebuilder 3500 traps

[Drew Van Order <dvanorder@DTTUS.COM>]

     Thanks James.

     3COM has been trying to convince me that this is a 'product feature',
     and of course, we know how vendors will often do anything to avoid
     blame for something poorly written. To answer your question, I do get
     3 event cards. However, the same trap type (power_supply_failed) is
     used for each one, and if I understand correctly, setting the trap
     type to log only would stop everything from going to TEC. Attached is
     what appears in trapd.log--might help explain.

     Thanks

Well, I don't have this hardware, but the only way you can stop three traps
coming to NetView is ask 3Com how to configure their device so that it only
sends one.

mib2trap has nothing to do with correlation -- he just creates a script with
addtrap commands which will add these traps, in some default format, to those
already defined in trapd.conf.  Thus when the three traps arrive they will have
some message associated with them rather than "NO FMT FOUND".  But you will
still get all three traps.  That won't change.

By three tickets, do you mean three event cards?  You will still get those too,
unless the Event Category for two of the traps is changed to "Log Only".   Then
all three will get written to the trapd.log, but only one will display in the
window.   Obviously, the "real" solution is have 3Com not send but one trap in
the first place.  But if you cannot do that, then you can suppress the other
two.

     All,

     I'm working with 3COM regarding traps sent to NetView from a CB 3500
     layer 3 switch. The issue is the power_supply_failed trap. When you
     pull one of the redundant supplies, you get 3 separate traps, each of
     which is power_supply_failed, but with a unique OID that states 5
     volts, 12 volts, and A/C failed.

     If 3COM chose to create 3 traps instead of one, this would not be an
     issue, but I must now somehow customize/correlate within NetView so I
     don't get 3 tickets ( I'm using mib2trap). I'm fairly new to
     customizing traps--is this common in the SNMP world, or do some
     vendors just supply substandard MIBs? Can others who have CB3500's
     provide any advice?


     Thanks,


     DVO
