I hope you're fine
I submit you the following problem.
I installed NMMi 9.20 on Redhat 5.6 ( Tikanga )
Installation is OK.
I loaded 3 MIBs provided by vendors.( Tools > Load/Unload MIBS )
Traps have been loaded.
Message of System
The following traps were already configured and have been updated:
alarmListReBuild - .18.104.22.168.22.214.171.124.2.0.4
alarmCleared - .126.96.36.199.188.8.131.52.2.0.3
alarmChanged - .184.108.40.206.220.127.116.11.2.0.2
alarmNew - .18.104.22.168.22.214.171.124.2.0.1
Traps have been enabled ( Configuration > Incidents >SNMP Trap Configurations )
I performed successfully a test with nnmsnmpnotify.ovpl to issue a "basic" Trap.
Node have been configured.
"Configuration Poll" is OK.
"Communication settings" shows that everythink is OK ( Active SNMP Agent, SNMPv1 used, ports 161,162 etc ... )
Thanks to tcpdump on its interface, I can see that my Server receive several traps from the managed node.
Example of received trap :
User Datagram Protocol, Src Port: snmp (161), Dst Port: snmptrap (162)
Simple Network Management Protocol
version: version-1 (0)
data: trap (4)
enterprise: 126.96.36.199.188.8.131.52.2 (iso.184.108.40.206.220.127.116.11)
agent-addr: 172.25.52.40 (172.25.52.40)
generic-trap: enterpriseSpecific (6)
variable-bindings: 8 items
=> that indicate an "alarmCleared" trap. ( alarmCleared : .18.104.22.168.22.214.171.124.2.0.3 )
Without interruption, Server receive flood of alarms from the Node.
Unfortunately, no trap appareared on the node. ( Network Overview > the Node > Incidents window )
It looks like that traps are not distributed on node.
Have you an idea please ?
How NNMi deal with received traps ? ( have we got any logs ??? )
Many thanks for your help

Thanks for your help
In fact, problem is due to system configuration.
A firewall have been implemented.
When you perfom iptables -L , you can list implemented rules.
In my case, snmp was not authorized.
We removed the tables thanks to iptables -X and now HPOV works well
See you soon :)
