SNMPv3 User Table
The Configure SNMPv3 User Table menu allows you to create an
SNMPv3 user and provides the options of configuring authentication and
privacy protocols. With the SNMPv3 protocol, users are authenticated
when they send and receive messages. In addition, you can configure a
privacy protocol and password so messages a user sends and receives
are encrypted. The DES privacy algorithm uses the privacy password and
the Engine ID to generate a key that is used for encryption. Lastly, you can
configure a storage type for this table entry which allows you to save this
user and its related configuration to flash memory.
SNMPv3 View Table
The Configure SNMPv3 View Table menu allows you to create a view of
the MIB OID Table. First, you configure a view of a subtree. Then you
have the option of configuring a Subtree Mask that further refines the
subtree view. For example, you can use a Subtree Mask to restrict a
user’s view to one row of the MIB OID Table. In addition, you can chose to
include or exclude a view. As a result, you can let a user see a particular
view or prevent a user from seeing a particular view. Lastly, you can
configure a storage type for this table entry which allows you to save this
view to flash memory.
SNMPv3 Access Table
The Configure SNMPv3 Access Table menu allows you to configure a
security group. After you create a security group, you assign a set of users
with the same access privileges to this group using the SNMPv3 Group
Table. Consider the types of groups you want to create and the types of
access privileges each group will have. In this way, you can more easily
keep track of your users as belonging to one or two groups.
For each group, you can assign read, write, and notify views of the MIB
table. The views you assign here have been previously defined in the
Configure SNMPv3 View Table menu. For example, the Read View allows
