To support user-based security for SNMPv3, LSMS provides the menu options. These menu options are accessible only when the SNMP Global Mode is set to SNMPv3 ONLY or Both. Following is an example of the Add menu.
The Group Name must be unique, 1 - 32 alphanumeric characters in length, and is case sensitive.
| Level | Authentication | Encryption | Details |
|---|---|---|---|
| noAuthNoPriv (no authentication, no privacy) |
Username | No | Uses a username match for authentication |
| AuthNoPriv (authentication, no privacy) |
Yes (SHA) | No | Provides authentication based on the algorithms available in the net-snmp API |
| AuthPriv (authentication and privacy) | Yes (SHA) | Yes (DES/AES) | Provides authentication and encryption based on the algorithms available in the net-snmp API |
The Read View name is optional, and must be specified exactly as configured in the view. The specified view must already be configured to be added to the group. If a read view is not selected for a group, the group will not have read access to any of the LSMS MIB objects.
The Write View name is optional, and must be specified exactly as configured in the view. The specified view must already be configured to be added to the group. If a write view is not selected for a group, the group will not have write access to any of the LSMS MIB objects.
A group that is associated with any user cannot be deleted. For information about users, see SNMPv3 User Management.
