Re: [nv-l] SNMP v2

[James Shanks <jshanks@us.ibm.com>]

You neglected to say what OS platform and what Level of code are you using.    I know it has to be UNIX, but . . . 
There have been recent small changes made in SNMP V2 trap processing.  I would suggest you call Support and get the latest fix if you cannot wait for FixPack2.

In particular I have seen issues where trapd was not able to parse the timestamp in the event, and so it was rejected as invalid, even though everything else was OK.  But you will need the latest level of code so that you can get a meaningful  trapd.trace  that will explain why the trap is being rejected.  7.1.3 FP1 and lower will not tell you.   Though you can set the "hex dump all packets" option for trapd (which makes him run with -x as an option) and then toggle the trapd trace on with "trapd -T "and see what the incoming packet actually looks like in hex.  What you won't see is why we think it is invalid.  Support can help you decode the hex if you want, though using the latest level might make that unnecessary.


As for the mib2trap insertion, that only affects formatting, it has nothing to do with whether a trap is rejected as invalid.

You would need to look at your trapd.conf with xnmtrap and see whether indeed the addtrap scripts, which  you created with mib2trap and ran,  actually put in an entry for enterprise 1.3.6.1.4.1.2552.200.300.3, generic trap 6, specific 4.  If that was not added, then that is why you see "no format found".   That is the trap that trapd says he got.  Is that the enterprise id you were expecting?   If not, then that is something else you may want to discuss with Support.

Hiya folks,
 
It appears that Netview is having problems with processing SNMP v2 traps. 
 
We get the following from Netview when we receive our Siteminder traps arrive:

Here is what came from Netview when it received the SNMP trap from Siteminder:

I have the traps properly inserted into Netview via mib2trap and had no problems whatsoever.
