Configuring SNMPv3 user settings
SNMPv3 settings are under Settings > System Settings: SNMP v3.
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.
Complete these steps 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.
Configure these settings to create SNMPv3 users:
Add a New User
Displays the controls to add a new user.
User Name
Specifies the username.
Authentication Protocol
Specifies an authentication method.
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
Specifies either Supply a Password or Supply a Key to use while authenticating users.
Password/Password Confirm
Specifies a password. The password must have a minimum of eight characters. Retype the password in the Password Confirm text field.
MD5 Key
Specifies a unique authentication key. The key is an MD5 or SHA digest created using md5sum or sha1sum. (This option appears only when you select Supply a Key.)
Use Privacy Option
Configures privacy using encryption.
Privacy Protocol
Specifies the encryption standard: AES or DES.
Privacy
Specifies one of these 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.
