Simple Network Management Protocol
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.
Command Usage
Configuring SNMPv1/2c Management Access
To configure SNMPv1 or v2c management access to the switch, follow these steps:
1. Use the Administration > SNMP (Configure Global) page to enable SNMP on the switch, and to
enable trap messages.
2. Use the Administration > SNMP (Configure User - Add Community) page to configure the
community strings authorized for management access.
