Access to the switch from clients using SNMPv3 provides additional security features that cover
message integrity, authentication, and encryption; as well as controlling user access to specific
areas of the MIB tree.

The SNMPv3 security structure consists of security models, with each model having it’s own
security levels. There are three security models defined, SNMPv1, SNMPv2c, and SNMPv3. Users
are assigned to “groups” that are defined by a security model and specified security levels. Each
group also has a defined security access to set of MIB objects for reading and writing, which are
known as “views.” The switch has a default view (all MIB objects) and default groups defined for
security models v1 and v2c. The following table shows the security models and levels available and
the system default settings.

NOTE

The predefined default groups and view can be deleted from the system. You can then define
customized groups and views for the SNMP clients that require access.
