SCOM 2012 SP1 - Show on event view all snmp trap (SNMP monitoring work)

Question

Hello everybody, 
Sorry for my english, I write normaly in french, but we have more result in english. 
I have a problem with SCOM 2012. I try to catch all snmp traps sended by a 2960 CISCO switch on a EventView with a specific rule (Authoring->Rule->Collection Rules -> Event Based -> SNMP Trap (Event) based on the object target "Node")
I creat a specific management pack juste for the rule and the views. 
SNMP Monitoring - CISOC 2960 => It's OK, I can have the processor state, utilization, etc ...
SNMP Monitoring Ubuntu computer => It's OK, I can have all the state I want.
SNMP Traps => The switch or the computer send traps over the network, and I can see in wireshark, the server receive the traps
SNMP Service (Windows service) => Disabled
SNMP trap (Windows service) => Disabled
Health Service (Windows service) => Enabled
Port 162 UDP => Open and listenning by the MonitoringHost.exe
Firewall rules => Everythinks is OK
SNMP Trap send version is => 2c
SNMP Monitoring device version is => 2c
I try too many of solution on different web site like :

Do you know a workaround? Or a different way to catch all the traps from a network device and show them (traps) on a event views.
Thank you in advance.

Hello Yan Li,
I read your link, and I found this : 
The network devices must be discovered and registered as ICMPSNMP devices.
And when I make the dicovery the first time, ICMP doesn't work, so I put only SNMP. This morning I tried with ICMP and SNMP, but the same problem come to me. And I found the rootcause of the problem with this post : http://www.code4ward.net/main/Blog/tabid/70/EntryId/105/Troubleshooting-Network-Discovery-in-SCOM-2012.aspx
I allowed the SNMP service, ping, and Health Service, just after I try a second time to dicover my device and it's work (ICMP and SNMP).
I recreat all my management pack and the rule. And now it's work! Thank you very much for your help!!
Have a nice day
Best regards
