iLO snmp pass-thru for firewalled hosts

Hi,

Following the guide "Managing HP servers through firewalls with Insight Software" I enabled SNMP pass-thru on the ILO and (from the guide, case 2 separate management network section):

 

For best protection of the servers operating inside the DMZ, administrators should set the SNMP trap
destinations to the loop back address and enable the SNMP pass-through in iLO 2 so that SNMP

traps are routed onto the iLO management network

 

But I never see a trap coming back...testing with:

 

snmptrap -v 1 -c public localhost NET-SNMP-EXAMPLES-MIB::netSnmpExampleNotification "" 6 17 "" netSnmpExampleInteger i 123456

 

or other community strings like allowhpsubagents or my private one, no traps are forwarded.

 

Looking at the network listeners, there is no process listening on UDP 162 (snmptrap) so I can't see how this "set trap destinations to localhost" would work.

 

of course the SIM identify fails totally as no SNMP responses are received...

 

Anyone got this working? O/S is Solaris but logic should be the same anywhere...
