Hi all, and thanks for all your help,
I am attempting to write a subagent, and at the moment I'm a little confused
about how to initiate my own coldStart/WarmStart traps.
The first problem I was facing was that these traps were already being sent by
the agent with the enterprise of net-snmp, and not "mine" = the one in the
system mib implemented by my subagent. I found the record that explained how to
disable them, by removing the "send_easy_trap" calls in the agent code, and did
just that.
Now I need to generate these traps without any additional varbinds.
I init a session as I do for all other enterprise specific traps I send - no
problem there.
Then I tried both using send_easy_trap(0, 0), or send_v2trap (as I do for all
the other traps) - with calling just
snmp_varlist_add_variable(
¬ification_vars,
objid_snmptrap,
objid_snmptrap_len,
ASN_OBJECT_ID,
(u_char *)
coldStart_notification_oid_p, coldStart_notification_oid_len * sizeof(oid));
In both cases I get the trap coming with the snmpTrapEnterprise =
SNMPv2-SMI::enterprises.8072.3.2.10..
I understand that I can change it manually (in my code), but I am missing
something here: if I use send_v2trap as above, how and why is the
snmpTrapEnterprise added? And where is it defined that the above enterprise
value is sent?
And using send_easy_trap, it says in the documentation "the enterprise and
enterprise_length paramater is set to the pre defined SYSTEM_MIB oid and length
respectively". What exactly does that mean?
I apologize for the length, was trying to be clear.
Huge thanks in advance,
-Tanya
