Cisco Router - Unable to get interface list from node

[lofti_213]

By playing with the configuration of that node, changing the community string to a faulty string, there's a notification saying that communication with snmp agent is lost.
But once i put the correct community string, and force polling, it says in the log :

[17.08.2016 15:43:15] **** Poll request sent to server ****
[17.08.2016 15:43:15] Poll request accepted

[17.08.2016 15:43:17] Node configuration was changed after poll
[17.08.2016 15:43:17] **** Poll completed successfully ****

Which means that the snmp communication between the node and server is ok.
But, i still do not find the interfaces of my router, discovered.

Hi,

please set debug level to 6, run configuration poll, and show all log records related to that router.

Best regards,
Victor

Hello Sir,
I set the debug level to 6 and re-run polling on node R1 which is a Cisco Router, in the same LAN (to remove any possibility of security checks) and filtered the event log to display only entries related to R1.
Thank you in advance.

Here is another log file after about 4 hours, thought that might contain more information.

I rebuilt NetXMS environnement with a fresh install of the OS, SQL and a different router, but always the same result.
I don't know what i am missing..

[lofti_213]

Here is the result of the command "debug snmp packets" i used to see if there's communication between NetXMS server and that router.

Have you tested polling the node with the setting (under "Polling" on the node) "Use ifXTable for interface polling" either on "Enable" or "Disable"?
I don't have a access to a Cisco 3750, so I can't test this directly.

[lofti_213]

Thank you for your reply, I already tested changing the "Use ifXTable for interface polling" parameter. What i noticed yesturday, that interfaces were read once, but when i tryed to force full configuration polling again, everything was lost.

Besides, i already changed the 3750, to 7200.

I have a stack of 4 C3750E here with no problems in NetXMS, SNMPv3. If I can test something for you, please ask.

Is it possible to provide me remote SNMP access to that device? I'll be able to debug it then.

Best regards,
Victor

[lofti_213]

Thank you for your reply,
I really feel confused right now, because, even Servers (MS Windows Server) that i want to monitor with SNMP, their SNMP information (OBJECT OID,...) are not displayed.
Victor, for the access, the router is not published on internet. and that might be refused here, but i can manage to give you access with Teamviewer if you permit. We make an appointment so both of us would be connected, and you'll have access.

Hi,

we can have session tomorrow after 14:00 EET. Please send me private message with your contact details.

Best regards,
Victor

[lofti_213]

I sent you contact information for Teamviewer in private message.
Thanks in advance.

Hello, did you receive information I sent you, Virctor?
