I have exactly the same problem with model enterprises.11863.5.122
No vendor found (unknown) and missing same data, do someone solved the problem?

I can only add that the switch seems not to give "vendor"

Looking in /home/netdisco/perl5/lib/perl5/SNMP/Info/Layer2 there doesn't seem to be a device class for tp-link/omada switches. Someone would need to create one for the switches to be recognized and polled properly.

if there is no specific module for a device / vendor snmp::info will fall back to a more generic class based on sysservices.
depending on how standard / non-standard they made their snmpd this has a good chance to at least fill out whatever we can find for clients, ports, etc...

to add basic support for a device (like os version & such) we need 3 things, each step becoming harder:

  1. an snmp snapshot of the device: https://github.com/netdisco/netdisco/wiki/Snapshot#netdisco-option
  2. the vendor specific mibs, if possible a recent version & as complete a set as possible
  3. time

that said, adding support for the very basics like os, model, etc... is quite doable. this example pretty much only adds vendor mapping and some other basics:
https://github.com/netdisco/snmp-info/blob/master/lib/SNMP/Info/Layer3/Redlion.pm
you can always use that as a template for adding basic support.

the master list to decide which module snmp::info uses is pretty much this:
https://github.com/netdisco/snmp-info/blob/b94140b5d201c3d99b2da57c194229bc6658ec96/lib/SNMP/Info.pm#L1750

after searching a bit i found a somewhat recent list of mibs, i can start by adding those. if you have a newer version do let me know.

https://www.tp-link.com/us/support/download/tl-sg2428p/#MIBs_Files
privateMibs(20220831).zip

also, mention netdisco/snmp-info#485 - seems to be the same question
