You can configure SNMPv3 on a node to allow SNMP get and set access to management information and configure a node to
send SNMPv3 traps to trap destinations in a secure way. SNMPv3 can be configured in secure mode, non-secure mode, or
disabled mode.

disabled mode.
SNMP, when configured in secure mode, only allows SNMPv3 messages that have the authPriv security level. SNMP messages
without authentication or privacy enabled are not allowed. When SNMP is configured in non-secure mode, it allows SNMPv1,
SNMPv2, and SNMPv3 message types.

Retrieves a value from a specific variable.
get-request
Retrieves the value following the named variable; this operation is often used to
retrieve variables from within a table. With this operation, an SNMP manager does
not need to know the exact variable name. The SNMP manager searches sequentially
to find the needed variable from within the MIB.

SNMP Management Information Bases
A managed object, sometimes called a MIB object, is one of many specific characteristics of a managed device. The MIB consists
of hierarchically organized object instances (variables) that are accessed by network-management protocols such as SNMP.
