Fw: [nv-l] SNMP v2c

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

OK, I've spoken with the Level 2 guy
handling this PMR (80103,487,000)
and I think we are now on the
same wavelength.

The Level 2 guy told me you are having
a problem with some V2 traps showing up in the NetView trapd.log as invalid
but you don't know why.

My suggestion is that you set the "hex
dump all packets" option on trapd and turn on the trapd.trace.
The hex dump option makes trapd run
with the "-x" operand so you can check it with "ps -ef |
grep trapd".  When you see that the -x is there, then you can
turn on the trapd trace with "trapd -T".   Then when your
suspect SNMP V2 trap arrives, the trace file will show the hex version
of the incoming V2 trap, plus the hex version of the SNMP v1 trap we translated
it into, and if, possible a message about what we think is wrong with the
trap.  That level of detail was added in 7.1 4 FixPack1 and 7.1.3
FixPack 3.   It should help you understand what is wrong with the
trap.  If you are still confused, collect the trace data, and send
it to the Level 2 guy for analysis. 

Hope this helps

YES!!!! I mean exactly that.  NetView
for UNIX can receive and process SNMP V2c traps just exactly like it does
SNMP V1 traps.
The reason is that when an SNMP V2c
 trap is received, trapd checks it for validity, and if valid, it
generates an SNMP V1 duplicate and puts that on its queue to process, dropping
the original V2 one, so all applications down the line see the same pdu
structure they always have.

Thus you can format SNMP V2 traps in
trapd conf, use them in rulesets, and so on.

Also James, when you
write "NetView

you mean Netview can process v2 traps just like it can v1 traps, right?

NetView for UNIX can receive SNMP V2 traps.  It has since Version
4.1.2.    Currently NetView for Windows cannot.  After 7.1.4
FixPack2 NetView for Windows WILL be able to receive and format SNMP V2
traps in just the same fashion as NetView for UNIX.

Would you be so kind as to send me the PMR number for the interaction with
IBM support in which your colleague was given erroneous information so
that I might set them straight?

NV 7.1.3 / AIX 5.1 
  
IBM support just told a peer that Netview can not accept v2c traps. He
had support repeat it three times. Support said there is another process
that converts v2c traps to a Netview acceptable format.
  
Can I, or can I not, have Netview load, accept, and process v2c SNMP traps
without any modifications?
