Bart, I'm definitely getting closer now. I can now send a linkUp trap from my software using SNMPv2. My code looks like this:
my $host = '10.50.80.197';
my $session= new SNMP::TrapSession(DestHost => $host, Community =>
"public", Port => 162, Version => '2c');
$session->trap(oid => "linkUp", [["ifIndex",1,1],
["sysLocation",0,"Here"]]);
Why do you include the sysLocation.0 mib item when sending the LinkUp
trap?
As you can see I have omitted the uptime field in the call to the trap
function.
This results in the following output from snmptrapd:
Received 106 byte packet from UDP: [10.50.80.197]:1366->[0.0.0.0]:0

[10.50.80.197]:1366->[0.0.0.0]:0]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (3384772387) 391 days,

IF-MIB::linkUp IF-MIB::ifIndex.1 = INTEGER: 1 SNMPv2-MIB::sysLocation.0
= STRING: Here
The timeticks value does not seem to be a sensible value unfortunately as
I have certainly not been running my agent for 391 days!
I have changed my code to try and send my user defined trap as follows but
without any success so far i.e. no trap is received by snmptrapd:
my $host = '10.50.80.197';
my $session= new SNMP::TrapSession(DestHost => $host, Community =>
"public", Port => 162, Version => '2c');
$session->trap(oid => "ssaSwitchStopped");
The ssaSwitchStopped trap has no additional varbinds associated with it.

Ali
