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-S111 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 69.
Figure 69. MIB Tree
The AT-S111 Management software supports the MIB tree, starting with
the Internet MIBs, as defined by 1.3.6.1. There are two ways to specify a
MIB view. You can enter the OID number of the MIB view or its equivalent
text name. For example, to specify MIBs in the Internet view, you can enter
the OID format “1.3.6.1” or the text name “internet.”
