Configuring the Switch

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.
