Create an SNMP v3 User

The SNMP v3 user sends SNMP traps and MIB (management information base) data to the STA server.

Requirements

The authorization method must be SHA (Secure Hash Algorithm), and the privacy method must be DES (Data Encryption Standard).
All SNMP libraries must use the same SNMP v3 credentials. Define a unique SNMP v3 user for this purpose and then define this same user on all monitored libraries.
Do no not use the values "public" or "private" for the SNMP v3 username, as these values are well known and present a security risk. Use values that are not as easily discovered. The username can only contain alphanumeric characters (a–z, A–Z, 0–9). Special characters are not allowed.
Authorization and privacy passwords must be at least eight characters in length, and cannot contain commas, semicolons, or equal signs.

SL500, SL3000, and SL8500

Note:

All SNMP libraries must use the same SNMP connection credentials. Define the same username and passwords on all SNMP libraries that will be monitored by this instance of STA.

Using CLI, create an SNMP v3 user:
```
> snmp addUser version v3 name name auth SHA authPass auth_password priv DES privPass priv_password
```
Where:
- name is the SNMP v3 username
- auth_password and priv_password are the authorization password and privacy password.
For SL3000 and SL8500 libraries, enclose variables in single quotes. For example:
```
SL3000> snmp addUser version v3 name 'STAsnmp' auth SHA authPass 'authpwd1' priv DES privPass 'privpwd1'
```
For SL500, do not use quotes. For example:
```
SL500> snmp addUser version v3 name STAsnmp auth SHA authPass authpwd1 priv DES privPass privpwd1
```
List the SNMP users to verify that the SNMP v3 user has been added correctly.
```
> snmp listUsers
```

SL150

Note:

All SNMP libraries must use the same SNMP connection credentials. Define the same username and passwords on all SNMP libraries that will be monitored by this instance of STA.

In the browser interface, select SNMP in the navigation tree.
In the SNMP Users section, select Add SNMP User .
For Version, select v3, and then complete the information as follows:
- User Name: The name of the SNMP v3 user.
- Authentication Protocol: Select SHA.
- Authentication Passphrase: Specify an authorization password.
- Privacy Protocol: Select DES.
- Privacy Passphrase: Specify a privacy password.
