Set up SNMP V3 user

You can set up an SNMP user for V3. The following table describes the configuration settings.

Table 1 Configuration Settings for SNMP User for V3

Field

Description

Server

This setting displays as read only because you already specified the server.

User Name

In the field, enter the name of the user for which you want to provide access. The name can contain up to 32 characters and can contain any combination of alphanumeric characters, hyphens (-), and underscore characters (_).

Tip   

Enter users that you have already configured for the network management system (NMS).

For existing SNMP users, this setting displays as read only.

Authentication Required

Check to require authentication, then enter the password in the Password and Reenter Password fields, and select the appropriate protocol. The password must contain at least 8 characters.

Privacy Required

If you checked Authentication Required, you can specify privacy information. Check to require privacy, and then enter the password in the Password and Reenter Password fields, and select an appropriate protocol. The password must contain at least eight characters.

Accept SNMP Packets from any host

To accept SNMP packets from any host, select the radio button.

Accept SNMP Packets only from these hosts

To accept SNMP packets from specific hosts, select the radio button. In the Host IP Address field, enter a host from which you want to accept SNMP packets and select Insert. Repeat this process for each host from which you want to accept SNMP packets. To delete a host, select that Host from the Host IP Addresses pane and select Remove.

Access Privileges

From the list box, select one of the following options for the access level:

  • ReadOnly—The user can only read the values of MIB objects.
  • ReadWrite—The user can read and write the values of MIB objects.
  • ReadWriteNotify—The user can read and write the values of MIB objects and send MIB object values for a trap and inform messages.
  • NotifyOnly—The user can only send MIB object values for a trap and inform messages.
  • None—The user cannot read, write, or send trap information.

To change the trap configuration parameters, you need to configure a user with NotifyOnly or ReadWriteNotify privileges.

Apply To All Nodes
