How can I send you these MIB files because apparently I can't attach it here due to file size limits?

[victor]

Just send them to [email protected], preferably with some comments on where to look for information about VLANs and physical ports.

Best regards,
Victor

Just sent you two emails, one for each device, with hints on the MIB files along with few screenshots.
I will send you similar information regarding other models of AT shortly.
Im looking forward to new NDD's.

Thanks,
Iliyan

Have you created NDD's for AT switches yet? I am eagerly checking every ChangeLog since my last reply and haven't seen anything about AT. 

[victor]

Sorry, not yet. At some point I completely forgot about it I've added a bugtracker issue (https://www.radensolutions.com/chiliproject/issues/367) so it will not be forgotten next time.

Best regards,
Victor

Thanks. Btw, have you consider adding Mikrotik NDD as well?

First of all, thank you for unlocking the topic.

The AT NDD driver seem to work only partially.
For GS950/48 I was able to see the switch port presentation (see on the attachment) however VLAN table is not shown correctly (it's empty). The correct OID that will collect VLAN information is .1.3.6.1.4.1.207.8.33.8. It will show this data:

...

With GS950/24 the problem is quite the opposite. There is now switch port information shown (PORT tab), however VLAN database is shown correctly (without port-to-vlan presentation).
If needed I can provide access to my NetXMS installation so you can perform any kind of tests you like. Just let me know.

Iliyan

Access to real equipment can really help. Can you contact me directly so we can organize it?

[vutoff]

You've got a message.

I have a similar issue with some dlink switches (not with netgear and cisco switches).

I get "VLAN list successfully retrieved from node"

[09.09.2018 20:54:13] **** Poll request sent to server ****
[09.09.2018 20:54:14] Poll request accepted

[09.09.2018 20:54:21] Finished topology poll for node Library
[09.09.2018 20:54:21] **** Poll completed successfully ****

but nothing shows up in the dlink VLAN column on the interfaces tab (cisco and netgear switch interface tabs show vlan information in vlan column)

Dlink MIB seems to be loaded because in the netxms MIB browser for the dlink switch I can see the vlan table OID for the switch, with OID as text and description filled as below, and SNMP walking it gives me vlan names and egress and untagged members

.1.3.6.1.4.1.171.10.76.9.7.6.1
