COM and VPFM
« on: September 03, 2013, 10:16:00 AM »
I've recently installed COM v3.0.1

COMis correctly installed but it cannot discover any devices. The communities and seeds used are the same we've used in VPFM, and in VPFM devices are discovered.

Does anybody have the same issue?
Another thing is how to increase VPFM SNMP/icmp timeouts?


Regards

That's probably what I'm going to do.

I just found it weird because its working with VPFM and not With COM, and after this post I found that COM v3.0.1 didn't support 8600/8800 v7.2, but reading 8800 v7.2 release notes I see
"Supported COM release
For Release 7.2, Avaya recommends using COM 2.3, 3.0 or higher"

I have about the same issue: installed COM, when running discovery, the software discovers the "core" switch, and the switches directly connected to the core. Only the core is online, the others are reported as offline. Switches further down the topology tree are not found.

I already tried reinstall, changing number of hops, timeout etc.. Even tried defining every switch as a separate ip in the seed table, but nothing untill now...

Do you use SNMP v1/2 or SNMP v3?

I had no problems to discover 50+ networks with COM.
There are a view points that you can try. 
@johann
If you discovered only the core it looks like a authentication issue on the other switches .
Do you have the correct communities,  are there access-list on the not discovered switches,  is SNMP allowed on all firewalls
That the traffic have to pass?

If nothing helps make a TCP dump on the COM server and check that you become SNMP packets from the switches you want to discover.
Itīs always the networks fault!

That was the first thing that came to mind, so I re-entered the security settings but without effect. I also tried with an easy community string and password like "test", but did not make a difference..

I currently have the same issue with 2 separate installations, already tried reinstalling etc but untill now I'm stuck..

Do you see SNMP traffic from the COM Server during the discovery process ?
Do you get any SNMP packtes from the Switches you try to discover back ?
Is the License correctly installed ?

Check that you have in the Device and Server Credentials Editor the correct communities and IP Ranges.

License and settings are correct, I triple-checked them together with the client.

I still need to investigate the issue further as soon as I find some space in my planning, and will check snmp communication between the software and the switches.

On wich System OS do you have installed COM ?
I prefer to run COM on Linux, had no problems so far with that combination.

All recent installations were on Windows 2008 R2 server, but haven't had any issues in the past.

The last 2 installation were both 3.0.1 and have the same issues, I tried upgrading 1 installation to 3.0.2 but it didn't fix anything..
