NetXMS Support Forum

I'm getting the following message when poll a avaya telecom switch.  I have multiple of these switches at the same software version, but I don't understand why one would return configuration information from a poll and other's wouldn't.  It appears that it cannot return information about interfaces on the switch.  Any ideas?

Unable to get interface list from node
 Interface "lan0" is no longer exists

I don't have any experience with Avaya devices, but some common problems are:
1) may be switch does not respond to SNMP requests at all, due to incorrect community string, firewall settings, etc.?
2) may be some sort of security configuration on the device which restricts MIB tree access, and NetXMS server does not have access to interface part of MIB tree?

Could you please post entire output of configuration poll?

Best regards,
Victor

I temporary got this resolved by a restart on the telephone switch, but continue to get the following error when polling configuration.

Could you please try to get interface list from PBX with different SNMP tool - for example, with GetIf (http://www.wtcs.org/snmp4tpc/getif.htm)? If other tools will return empty interface list, than we will know that problem is with PBX SNMP agent, but if you will be able to see interface list with other tools, that will mean the bug in NetXMS.

Hi, I am experiencing exactly the same fenomenum, GetiF does return the interface list but NetXMS reports "unable to get interface list"

I took the effort to investigate it a little further and took Wireshark traces of both NetXMS and GetiF. The OIDs that both NetXMS and GetiF utilizes are the same, the difference is that GetiF requests a whole bunch of parameters while NetXMS only requests the object name. Why an error is reported by NetXMS is puzzling me because snmp wise everything looks OK.

I have both traces attached.

Hi!

Could you please try version 1.0.0? I've fixed some bugs in interface poller, should help.

Best regards,
Victor
