In addition, you have the option of assigning no user authentication. In this
case, no authentication is performed for this user. You may want to make
this configuration for someone with super-user capabilities.
SNMPv3 Privacy
Protocol
After you have configured an authentication protocol, you have the option
of assigning a privacy protocol if you have the encrypted version of the AT-
S107 Management software. In SNMPv3 protocol terminology, privacy is
equivalent to encryption. Currently, the DES protocol is the only encryption
protocol supported. The DES privacy protocol requires the authentication
protocol to be configured as either MD5 or SHA.
If you assign a DES privacy protocol to a user, then you are also required
to assign a privacy password. If you choose to not assign a privacy value,
then SNMPv3 messages are sent in plain text format.
SNMPv3 MIB
Views
The SNMPv3 protocol allows you to configure MIB views for users and
groups. The MIB tree is defined by RFC 1155 (Structure of Management
Information). See Figure 98.
