Hi,
Conceptually, there's a big difference between get/set and traps:
get/set messages in SNMP are always requested by the management application and
responded to by the SNMP agent.
Traps, OTOH, are messages that are sent, unsolicited, from the agent to notify
the management app of something of interest that has happened without having to
wait for polling.
HTH,
Rony

Subject: SNMP: GET/SET vs. TRAP
Hi,
net-snmp's GET/SET mechanism looks completely separated from the TRAP
mechanism, which I find quite bizarre.
NET-SNMP claims to be easily extensible with Perl
(http://net-snmp.sourceforge.net/wiki/index.php/Tut:Extending_snmpd_using_perl)
However, this extension doesn't know what a TRAP is, only handles GET/SET
commands.
It seems as if I have two options:
A. Write a completely separate Perl daemon that sends traps using Net::SNMP
(completely separate code for sending TRAPs and handling GETs/SETs??)
B. Write a subagent in C (a separate process that "talks" to snmpd), which
handles both GETs/SETs & TRAPs. (Is that the common approach?)
Am I missing something?
Thanks
- Oren
