snmpwalk without specific OID doesn't show proprietary OIDs

[doron2020]

Hello, it is Siklu team

General snmpwalk is finished without the "No more variables left" line, and it doesn't show any proprietary OIDs (beginning with iso.3.6.1.4...)
Only a specific OID snmpwalk will show them
If we change the proprietary OIDs to begin with iso.3.6.1.2... then it will show them as well.

(finished but without "No more variables left in this MIB.." line)

Now If I do specific snmpwalk I can see the proprietary OIDs

Attached the yang file of the proprietary mib

Thanks!

Hi,

I'll try to reproduce this one and see if we can find the issue.

Thanks,
/K

@krihal Do you have any update regarding this issue? Do you need anything from us in order to resolve it?

[krihal]

If I understand it correctly you have extended the system MIB with proprietary OIDs? Can you explain a bit how that is implemented and also share the MIBs used?

[doron2020]

We have understood that it is normal behavior of snmpwalk since its default when no oid argument is subtree .1.3.6.1.2.1
