Chapter 1 Overview
SNMP (Simple Network Management Protocol) is a widely used protocol for monitoring the health and welfare of network equipment (e.g. routers). SNMP monitor devices can be computer, router, printer, ups or any other SNMP device.
SNMP in router implements SNMP v1, SNMP v2c and SNMP v3. The MIB file can be downloaded directly from the web interface. MIBs are Management Information Base's that describe the data structures that can be requested from an SNMP device. The router can also be managed via an SNMP tool with the MIB file.
The SNMP function is an App which needs to be installed into the router in the System->App Center unit.
Chapter 2 App Installation
2.1 Installation
Path: System->App Center
Place the SNMP App .rpk file (e.g., r2000-smnp-2.0.0.rpk) into a free disk of a PC. Log in to the router configuration page and navigate to System->App. The interface shows an 'App Install' section with fields for 'File', 'Choose File', and an 'Install' button.
[Screenshot Description: The 'App Center' interface displays an 'App Install' section. It includes a 'File' input field, a 'Choose File' button, and an 'Install' button. The 'Choose File' button is active, and the field next to it is empty or shows 'No file chosen'.]
Click the "Choose File" button, select the SNMP App .rpk file from the PC, and then click the "Install" button on the router configuration page.
[Screenshot Description: A file explorer window is open, showing a list of files. The user is selecting the 'r2000-snmp-2.0.0.rpk' file. The file explorer has options like 'Organize', 'New folder', 'Favorites', 'Libraries', 'Computer', and a 'File name' field showing 'r2000-snmp-2.0.0.rpk'. The 'Open' and 'Cancel' buttons are visible.]
When the installation progress reaches 100%, the system will display a reboot reminder window. Click "OK" to reboot the router.
[Screenshot Description: A 'Router Web Manager' dialog box appears with the message "Operation successfully completed. Do you want to reboot immediately?". It has 'OK' and 'Cancel' buttons.]
After the router powers on again, log in to the configuration page. The SNMP app will be listed in the App Center's "Installed Apps" list, and its configuration options will be available in the Services part.
[Screenshot Description: The 'App Center' interface shows the 'Installed Apps' list. One entry is listed with Index 1, Name 'snmp', Version '2.0.0', Status 'Stopped', and Description 'SNMP subagent'. Below this, the 'Services' menu is visible on the left, with 'SNMP' highlighted. The right pane shows 'SNMP Agent Settings' with options like 'Enable SNMP Agent' (toggle ON/OFF), 'Port', 'Version', 'System Name', 'Authentication Algorithm' (MD5), and 'Privacy Algorithm' (DES).]
2.2 Uninstallation
Path: System->App Center
Navigate to "Installed Apps" in the App Center, find the SNMP App, and click the "❌" icon next to it.
[Screenshot Description: The 'App Center' interface shows the 'Installed Apps' list. The SNMP app entry (Index 1, Name 'snmp', Version '2.0.0', Status 'Stopped') has a red '❌' icon in the last column.]
Click "OK" in the router reboot reminder popup window. When the router finishes restarting, the SNMP app will be uninstalled.
[Screenshot Description: A 'Router Web Manager' dialog box appears with the message "Operation successfully completed. Do you want to reboot immediately?". It has 'OK' and 'Cancel' buttons.]
