Hi Sims,
Once you have access through SNMP, you will have access to the entire Management Information Base (MIB).
With views, it’s possible to limit this to certain (sub)trees.
Cisco has some good examples here:
Like this one:
snmp-server view myview mib-2 included
snmp-server view myview atEntry excluded
snmp-server view myview cisco included
It includes access to the MIB-II and Cisco MIB but denies access to the atEntry MIB.
