User Security Model Configuration Menu
You can use a defined set of user identities using this Security Model. An SNMP engine must have the knowledge of the 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.

name - Set USM user name
auth - Set authentication protocol
authpw - Set authentication password

Command Syntax and Usage
name <32 character name>
 
Configures a string that represents the name of the user. This is the login name that you need to access the system.
Values: 1 – 32 characters
auth md5|sha|sha256|none
 
Configures the authentication protocol.
Values: HMAC-MD5-96, HMAC-SHA-96, HMAC-SHA256-96, none
Default: none
Note: If you use privacy type AES256, you must select authentication protocol SHA256.
authpw
 
Creates or changes your authentication password. If you selected an authentication algorithm using the auth command, you need to provide a password. Otherwise, you will get an error message during validation.
priv des|aes128|aes256|none
 
Privacy Type - Specifies whether messages sent on behalf of this user to and from the SNMP engine can be protected from disclosure, and if so, the type of privacy protocol that is used.
Values:
*none — Displays an error message.
*des — The CBC-DES Symmetric Encryption Protocol. If you specify this privacy protocol, make sure that you have specified an authentication protocol.
*aes128 — The Advanced Encryption Standard (AES) Cipher Algorithm. This is a stronger privacy protocol than the CBC-DES Symmetric Encryption Protocol.
*aes256 — The Advanced Encryption Standard (AES) Cipher Algorithm. This is a stronger privacy protocol than the CBC-DES Symmetric Encryption Protocol.
Default: none
Note: If you use privacy type AES256, you must select authentication protocol SHA256.
privpw
 
Creates or changes the privacy password.
del
 
Deletes the USM user entries.
cur
