SNMP version 3 (SNMPv3) is an extensible SNMP Framework that supplements the SNMPv2 Framework by
supporting the following:
a new SNMP message format
security for messages
access control
remote configuration of SNMP parameters
For more details on the SNMPv3 architecture please see RFC2271 to RFC2275.
The following table describes the SNMPv3 Configuration Menu options.
Table 69 SNMPv3 Configuration Menu options
Command
Description
usm <1-16>
Configures a user security model (USM) entry for an authorized user. You can also
configure this entry through SNMP. The range is 1-16.
view <1-128>
Configures different MIB views. The range is 1-128.
access <1-32>
Configures access rights. The View-based Access Control Model defines a set of
services that an application can use for checking access rights of the user. You need
access control when you have to process retrieval or modification request from an
SNMP entity. The range is 1-32.
group <1-16>
Configures an SNMP group. A group maps the user name to the access group names
and their access rights needed to access SNMP management objects. A group
defines the access rights assigned to all names that belong to a particular group. The
range is 1-16.
comm <1-16>
Configures a community table entry. The community table contains objects for
mapping community strings and version-independent SNMP message parameters.
The range is 1-16.
taddr <1-16>
Configures the destination address and user security levels for outgoing notifications.
This is also called the transport endpoint. The range is 1-16.
tparam <1-16>
Configures SNMP parameters, consisting of message processing model, security
model, security level, and security name information. There may be multiple transport
endpoints associated with a particular set of SNMP parameters, or a particular
transport endpoint may be associated with several sets of SNMP parameters.
notify <1-16>
Configures a notification index. A notification application typically monitors a system
for particular events or conditions, and generates Notification-Class messages based
on these events or conditions. The range is 1-16.
v1v2 disable|enable
Enables or disables the access to SNMP version 1 and version 2. This command is
enabled by default.
cur
Displays the current SNMPv3 configuration.

You can make use of a defined set of user identities using this Security Model. An SNMP engine must have the
knowledge of applicable attributes of a user.
This menu helps you create a user security model entry for an authorized user. You need to provide a security
name to create the USM entry.
The following table describes the User Security Model Configuration Menu options.
