Access control modes

SNMP uses the following modes to control access to MIB objects:

RBAC mode controls access on a per MIB object basis, and VACM mode controls access on a MIB view basis. As a best practice to enhance MIB security, use RBAC mode.

If you create the same SNMP community or user with both modes multiple times, the most recent configuration takes effect. For more information about RBAC, see Fundamentals Command Reference.
