Configuring System Settings : Creating SNMPv3 Users
  
Creating SNMPv3 Users
You create SNMP v3 users in the SNMPv3 page.
SNMPv3 provides additional authentication and access control for message security. For example, you can verify the identity of the SNMP entity (manager or agent) sending the message.
Using SNMPv3 is more secure than SNMPv1 or v2; however, it requires more configuration steps to provide the additional security features.
To create SNMP users
1. Create the SNMP server users. Users can be authenticated using either a password or a key.
2. Configure SNMP server views to define which part of the SNMP MIB tree is visible.
3. Configure SNMP server groups.
SNMP server groups map users to views, enabling you to control who can view what SNMP information.
4. Configure the SNMP server access policies that contain a set of rules defining access rights. Based on these rules, the entity decides how to process a given request.
To create users for SNMPv3
1. Choose Settings > System Settings: SNMP v3 to display the SNMP v3 page.
2. Under Users, complete the configuration using the controls described in this table.
Control
Description
Add a New User
Displays the controls to add a new user.
User Name
Specify the username.
Authentication Protocol
Select an authentication method from the drop-down list:
•  MD5 - Specifies the message-digest 5 algorithm, a widely used cryptographic hash function with a 128-bit hash value. This is the default value.
•  SHA - Specifies the secure hash algorithm, a set of related cryptographic hash functions. SHA is considered to be the successor to MD5.
Authentication
Optionally, select either Supply a Password or Supply a Key to use while authenticating users.
Password/Password Confirm
Specify a password. The password must have a minimum of eight characters. Retype the password in the Password Confirm text field.
MD5 Key
(Appears only when you select Supply a Key.) Specify a unique authentication key. The key is an MD5 or SHA digest created using md5sum or sha1sum.
Use Privacy Option
Optionally, select this setting to configure privacy using encryption. Configure the following:
•  Privacy Protocol - Specify one of the following encryption standards: AES or DES.
•  Privacy - Specify one of the following methods:
–  Same as Authentication Key.
–  Supply a Password - If you select this option, you are prompted to set and confirm a password.
–  Supply a Key - If you select this option, you are prompted to supply a key.
