Hi,
I'm referring to an older question of another User in this Forum (http://www.lansweeper.com/Forum/yaf_postst11320findunread_Any-way-of-debugging-SNMP-v3-queries.aspx#post42246)
We encountered a similar problem, that our Alcatel Switches are not able to be scanned via SNMP v3 through Lansweeper. Even the device-Tester is not able to get a reply from those devices. We double-checked everything, authentication, connection and even with a secondary tool (Paessler) to check if anything is possible.
First thing we found with Paessler:
1.3.6.1.2.1.1.2.0 works
1.3.6.1.2.1.1.2 not

Paessler shows that the Custom OID used by Lansweeper device-tester seems to be incorrect / not showing a result. The same OID added with a ".0" gives the result desired.
We already had contact via EMail to Lansweeper support but ended in "Please monitor the traffic between Lansweeper and the device with Wireshark" that then has been too much hassle for us. As shown above the main thing might be the OID.
Would someone be able to assist us in this matter? Could it be that the device-tester needs to be changed / fixed?
Another, second problem:
When those switches are stacked they will be recognized as ONE Element only (we did this with SNMPv2) and if you try to enter the stacks manually they will be merged to the master (without adding hardware-information / serial-no., etc.) to the lansweeper database afterwards.
Is there a chance to get at least the details of the merged element(s) to the entry of the stack?
Thanks in advance for any help,
Martin!
