           Summary: doesn't log all the SNMP packets
           Product: Wireshark
           Version: 0.99.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: High
         Component: Wireshark
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: elie_cohen@xxxxxxxxx

I am running Ethereal 0.10.0.a on a Linux 2.4.21-32.ELsmp (RHEL3 update 3)
compiled with GTK+ 1.2.10 with GLib 1.2.10 with libcap 0.7.2 with libz 1.1.4
without libpcre with net-SNMP 5.09 without ADNS.

We are Stress testing our NMS software by sending 250 traps/second from a
device emulator. Because the NMS software didn't receive all the traps sent, we
ran Ethereal to figure out if the traps were lost before reaching the system on
which our NMS software is running. The problem is that, in most cases, our NMS
software sees more traps than Ethereal.

we run ethereal with the following capture setup:

        Capture filter = port 162
        Capture file  -- Leave blank
        Check:
           o    Capture packet in promiscuous mode
           o    limit each packet to 68 bytes
        Uncheck everything else (DO NOT check name resolution checbox)

Is there a system parameter we need to change in order for Ethereal to see all
the SNMP packet the system receives.

Thanks,
Elie
