Go to *Network :: SNMP*. 2. Click **System** (displays dialog). ![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678466362216.png) 3. Two fields can be edited: 1. **SysContact** (email address) 2. **SysLocation** (location name) 4. If changed, click **Save**. 5. If not, click **Cancel** to return to table. ### Add SNMP Community/Username Configuration 1. Go to *Network :: SNMP*. 2. Click **Add** (displays dialog). ![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678467132125.png) 3. In the *Version*menu (select one): - **Version V1/V2** radio button (expands dialog). Enter **Community** and **Source**. (if applicable) **Enable SNMP for IPv6** checkbox. ![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678466958571.png) - **Version 3** radio button (expands dialog): ![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678467033857.png) Enter **Username**. On **Security** Level drop-down, select one (NoAuthNoPriv, AuthNoPriv, AuthPriv). On **Authentication Algorithm** drop-down, select one (MD5, SHA, SHA-224, SHA-256, SHA-384, SHA-512). Enter **Authentication Password**. On **Privacy Algorithm** drop-down, select one (DES, AES, AES-192, AES-256). Enter **Privacy Password** > [!WARNING] > Note > > Now when using the export_settings **command** in CLI there will be a behavior change. The fields authentication_password and privacy_password will no longer display the actual password values as this implementation will store SNMPv3 passwords in a hashed format. For this the service needs to be enabled on the *SECURITY::SERVICES::GENERAL SERVICES* page, under **Active Services**, **Enable SNMP Service** checkbox. > > Before the SNMP service is enabled: > > - It is possible to create and configure SNMPv3 users and traps even if the SNMP service is currently disabled. > - During this phase, SNMPv3 authentication and privacy passwords are stored in plain text in the system configuration. > - This is necessary so the system can apply the credentials correctly when the SNMP service is later enabled. > > After the SNMP service is enabled: > > - Once the SNMP service is enabled for the first time, Nodegrid will automatically hash all stored SNMPv3 passwords. > - From the point the service is enabled, SNMPv3 credentials are no longer stored in plain text. > - Subsequent updates to SNMPv3 passwords are also stored only in hashed form. > [!CAUTION] > Warning > > Executing “Apply Settings” on a device with a different MAC Address than the one used during “Save Settings” will break SNMPv3 functionality. In such cases, you must re-enter the passwords configured for SNMPv3 users and/or traps. > > This condition applies only to old installations in which “Save Settings” was executed on a device that was upgraded without disk reformatting. If “Save Settings” was performed on a new installation (i.e., after a software upgrade with disk formatting or after resetting the unit to factory defaults), “Apply Settings” will function normally. 1.
