SIM has stopped receiving SNMP traps - PLEASE HELP....

[SvenAndersen]

Hi.

we have a brand new install of a SIM CMS using v7.0

yesterday we discovered our c7000 enclosure and successfully sent a test SNMP trap, which was received in the SIM console.

then for no apparent reason, the traps suddenly stopped being received by SIM.

we have discovered the c7000 onanother SIM isntance and the traps are received fine.

we tried pulling a fan and a power cable from the c7000 and the graphical view of the enclosure clearly showed a Minor  icon on the fan and a Critical icon on the power supply...... but we did not receive the SNMP Trap.

this is about to go into production and would be VERY GRATEFUL if anyone can suggest what is wrong please.

MANY THANKS IN ADVANCE

Sven.

Did you switch the OA?

Is the second OA discovered by your SIM?

SIM does only display Events received by discovered system IP addresses.

Did you save the OA trap forwarding?

You should be able to send multiple time a test trap to a sim server.

Check for possible network devices which do not forward or filter SNMP traps.

If you are in the same subnet you should check with a tool like wireshark what happened to your trap.

Traps are handled different inside Insight Remote Support.

Removing a power supply is not a HW failure!!! Just in case you are testing IRS!!!

Hi,

thanks for the reply...

we have not switched the OA.

the second OA is discovered in SIM.

the OA trap forwarding is applied and saved.

this is a flat netowrk with nothing in the way of the traps.

we are not using Insight Remote Support.

before this all stopped working, we were receiving test traps, and traps when a fan was pulled from the enclosure.

Now we are receiving nothing.

we have cross checked all the SIM and Server configurations with our "working" SIM server, and it appears to be identical.... unless we just don't know what to look for ??

Does anyone know of any command line utils which we can use to possibly diagnose the problem ?

ANY help will be appreciated.

many thanks.

Sven.

You need to sniff the traffic from the OA interface using a port span on the switch or otherwise and see if the snmp trap is being put on the wire. Also run a sniffer on the SIM server and see if it's arriving.

Hi all, It's fixed.

Partly our fault :-(

We put snmputil.exe on the SIM server and we noticed the traps were not being received.
Next, we put tcpview on the server and saw that ammo and opctrapi.exe were listening on port 162....
Tried wireshark too and saw the traps being recieved so had a think.

It turns out we had deployed some HP SIM policies from HPOM onto the HPOMagent in the SIM server. These policies enabled the opctrapi.exe process, which is a trap interceptor and directs traps into HPOM.

When we removed the policies and restarted the HPOM agent we didn't have the opctrapi process anymore. We restarted the HPSIM SERVICE, and the traps came into SIM.

thanks for the advice.

Sorry, first paragraph should have said " snmp and opctrapi.exe"

Cheers
