Actually no but dinking around with the syntax you mention it seems that if I use
snmp.name contains 1.3.6.1.4.1.9.9.26.1.1.1.1.17
which refs a trapvar bind that works for me as expected.
So I can can now filter out the noise.

Thanks for your help!

Graag gedaan:-)

Do you get matches when you use those filters?
snmp.name == 1.3.6.1.4.1.9.9.26.2.0.1
or
snmp.name == 1.3.6.1.4.1.9.9.26.2.0.1 || snmp.name == 1.3.6.1.4.1.9.9.26.2.0.2
|| snmp.name == 1.3.6.1.4.1.9.9.26.2.0.3 || snmp.name == 1.3.6.1.4.1.9.9.26.2.0.4
 

Thanks

Bedankt!
Tried that.
If use filter ="snmp.name contains 1.3.6.1.4.1.9.9.26" I get a subset of
trapd (still 10 000s) of traps roughly in line with what I am expecting.

For example:
..
SNMPv2-MIB::snmpTrapOID.0 (1.3.6.1.6.3.1.1.4.1.0): 1.3.6.1.4.1.9.9.26.2.0.2
(SNMPv2SMI::enterprises.9.9.26.2.0.2)
..
Actually I am looking for 1.3.6.1.4.1.9.9.26.2.0.1 to 1.3.6.1.4.1.9.9.26.2.0.4
traps.

But if I use filter =="snmp.name contains 1.3.6.1.4.1.9.9.26.2"
I get no matches.
Which is mysterious cos  I was expecting for sure to match this line ->
    
SNMPv2-MIB::snmpTrapOID.0
  
(1.3.6.1.6.3.1.1.4.1.0): 1.3.6.1.4.1.9.9.26.2.0.2 

Any suggestions?

TIA

Tony

yes, you can use "snmp.name contains 1.3.6.1.4.1" as a display filter within
Wireshark too  :-)
