Hello @kamil.swedrak
The best way to handle this is using a MIB Parser like Paessler MIB. Then you can find the MIB file, important and you´ll be able to see the OID:
https://sourceforge.net/p/netdisco/mibs/ci/1.5/tree/cisco/CISCO-UDLDP-MIB.my
For example. The OID for Global enable is 1.3.6.1.4.1.9.9.118.1.1.1.0
Interface enable 1.3.6.1.4.1.9.9.118.1.2.1.1.1
Interface Oper Status 1.3.6.1.4.1.9.9.118.1.2.1.1.2
etc,etc.
