I am new to Netview/AIX and still learning the system, so I don't know much
about the internals flow of events/traps through the system. I've seen a
similar situation receiving this trap, but it seems to process correctly.
I am also receiving many 'tcpConnectionClose' traps from two of my
core/central switches and one core router. No one has figured out why yet.
The first time this started happening, our Cisco engineer stopped the traps
by shutting off those snmptraps in the switch and router involved, i.e.
didn't fix it, just stopped forwarding the traps to NetView. Recently we
moved one of our central DLSW peers over to a new 7204 Cisco router, and
another switch started generating many of the 'tcpConnectionClose' traps.
Still, no one knows why. But we ASSUME it has something to do with the DLSW
To your question on the SNMP MIB ID. We had no problem here. The trap was
defined in the Cisco enterprise 22.214.171.124.4.1.9, and the trap event was
displayed correctly in the event display. To temporarily keep the event off
the event display, I went in to the Options-->Event Configuration-->Trap
Customization: SNMP... and selected the CISCO enterprise, then selected the
Cisco_tcpConnectClose event, and modified it to 'log only' to keep the event
off the event display. It sounds to me like you have this same Enterprise
defined on your system and it also contained this event, but the event is
not displaying correctly in your event window. I have no idea why your
system wouldn't match up the incoming trap to the event defined. Hopefully
someone else with more trap experience can help, otherwise Tivoli tech
If you ever find out why the tcpConnectionClose traps are being generated,
let us know.

However, in the Enterprise 126.96.36.199.4.1.9, this trap did
