I notice you did not tell us what version, release level, nor platform you
are seeing this is on.
I think from your description that you need NetView 7.1.3 Fixpack 1, which
has a fix for a problem ( IY35928) in which the last element of the
enterprise OID was being dropped during comparison for SNMP V2 traps.
If you don't have 7.1.3 contact Support and talk to them about what levels
a fix for IY35928 is available. If you do have 7.1.3 then put on the
Fixpack. Don't like this answer? Then please contact Support.

Subject: [nv-l] Problem with
SNMP v2 traps with mib2trap.
04/23/03 09:48 AM
Hi,
(Resending this message again since the earlier one sent on 11th April
did not appear on the mailing list.)
We are writting an SNMP agent for our application servers. Our agent
would support SNMP version 2. Our traps are not being displayed
formatted in the event browser in NetView. Following is sample trap from
our mib file
<snippet>
--
-- Traps
--
aaaTraps OBJECT IDENTIFIER ::= { versionOne 0 }
oblixAAAServerDown NOTIFICATION-TYPE
OBJECTS { aaaId, aaaHostname, aaaPort }
STATUS current
DESCRIPTION "This trap is generated whenever the agent detects the
AAA server to be (potentially) down."
::= { aaaTraps 7001 }
oblixAAAServerStart NOTIFICATION-TYPE
OBJECTS { aaaId, aaaHostname, aaaPort }
STATUS current
DESCRIPTION "This trap is generated whenever the agent detects the
AAA server to have (re)started."
::= { aaaTraps 7002 }
oblixAAAServerFailure NOTIFICATION-TYPE
OBJECTS { aaaId, aaaHostname, aaaPort }
STATUS current
DESCRIPTION "This trap is generated whenever the agent detects the
AAA server has failed."
::= { aaaTraps 7003 }
</snippet>
The same mib, when uploaded to HP OpenView NNM works fine, in the sense
that formatted message get displayed from HP OV. The event browser in
NetView displays the trap details in a raw fashion. It does not display
the formatted string configured for the trap.
Following is the script file generated after running mib2trap.
<script>
/usr/OV/bin/addtrap -l oblixAAAServerDown -g 6 -s 7001 \
-n aaaTraps -i 1.3.6.1.4.1.3831.10.2.1.0 \
-o A -c "LOGONLY" -t 0 \
-S 1 \
-D "This trap is generated whenever the agent detects the
AAA server to be (potentially) down." \
-e oblixAAAServerDown \
-F '$E $G $S $# args: $*'
/usr/OV/bin/addtrap -l oblixAAAServerStart -g 6 -s 7002 \
-n aaaTraps -i 1.3.6.1.4.1.3831.10.2.1.0 \
-o A -c "LOGONLY" -t 0 \
-S 1 \
-D "This trap is generated whenever the agent detects the
AAA server to have (re)started." \
-e oblixAAAServerStart \
-F '$E $G $S $# args: $*'
/usr/OV/bin/addtrap -l oblixAAAServerFailure -g 6 -s 7003 \
-n aaaTraps -i 1.3.6.1.4.1.3831.10.2.1.0 \
-o A -c "LOGONLY" -t 0 \
-S 1 \
-D "This trap is generated whenever the agent detects the
AAA server has failed." \
-e oblixAAAServerFailure \
-F '$E $G $S $# args: $*'
</script>
In the event browser, the enterprise is shown as "aaaTraps". However,
aaaTraps is a dummy place-holder OID, that we have defined to comply
with RFC 2578 in section 8.5 (Mapping of the NOTIFICATION-TYPE value).
We noticed that HP-OV NNM displays the enterprise properly as
"versionOne". We think that the event browser is not displaying the
formatted message for the traps because it can't correlate the incoming
trap with the proper enterprise (since the enterprise has been picked up
as "aaaTraps" instead of "versionOne").
We plan to support both HP-OV NNM and IBM Tivoli for our release. Please
let me know if I am missing something over here or there is something
else that needs to be done.
Regards,
Paresh.
