[SNMP4J] SnmpRequest usage

[BRESCIANI, MARCO (MARCO)]

I've tried again... this time works... :S and keeps running. Seemed a problem related to some strange Windows SW that got the SNMP port...

Anyway, I'm now analysing the missing trap part.

Hello Marco,

I had the exact same problem. Wireshark received the traps, but my trap listener didn't.
I used someone's suggestion and it helped:
Don't listen on address 151.98.92.112 but on 0.0.0.0.
Snmp agents normally send their traps to port 162, not 161, so check this one as well.

So- try 0.0.0.0/161<http://0.0.0.0/161> (or 0.0.0.0/162<http://0.0.0.0/162>).

Good Luck,
Tsiyona

Ah, and by the way - I also work for Alcatel-Lucent!

Hello all,
 I'm trying to use the SnmpRequest object in the org.snmp4j.tools.console package to listen for TRAPs, to verify a strange behaviour I'm facing with.

While Wireshark detects the TRAPs, SNMP4J does not receive it or anyway does not forward the TRAP to my application.
 Since it happens with very few specific TRAPs, I thought to use the SnmpRequest to debug the internal behaviour.

I'm using this command line:

java -classpath ./;./snmp4j-1.11.1.jar org.snmp4j.tools.console.SnmpRequest -p TRAP -c private -v 2c -d DEBUG -Ol udp:151.98.92.112/161<http://151.98.92.112/161>

being 151.98.92.112 my PC address, but I do not see any TRAP, not even the "normal" ones when I'm using my application and changing values on the network element to generate TRAPs.

Any suggestion?

Thanks,
