Custom root OID

[parisum]

Hello Everyone
I'm trying to add a snmp based device to my Zabbix4. so far I've installed snmp-mibs-dowloader on my ubuntu and added the Mib file [ http://iot.fit-foxconn.com/iSCadmin/....00%5b1%5d.mib ] to /usr/share/snmp/mibs/ folder.
My problem is the device doesn't show the oid tree properly if I walk the device without any OIDs :

snmpwalk -v1 -c public

[output: https://paste.debian.net/1126267/ ]
However it shows the right data if I add an OID to my command:

snmpwalk -v1 -c public 192.168.0.21 iso.3.6.1.4.1.2468.1.3.1

[output: https://paste.debian.net/1126268/ ].

How is it possible to tell Zabbix to start the tree from a custom OID ?

I only have simple snmp checks, by your question i'm assuming that you are trying to create SNMP discoveries.
I can be wrong, but i think that in the discovery you specify a 'starting OID'.
Have you checked the discoveries in the existing snmp templates?
