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 137.

Figure 137. MIB Tree

The AT-S63 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.”

In addition, you can define a MIB view that the user can access or a MIB
view that the user cannot access. When you want to permit a user to
access a MIB view, you include a particular view. When you want to deny
a user access to a MIB view, you exclude a particular view.

After you specify a MIB subtree view you have the option of further
restricting a view by defining a subtree mask. The relationship between a
