NetFlow Analyzer uses flow technology to provide real-time visibility into your network bandwidth performance. The first and most crucial step in monitoring your network bandwidth is exporting flows.
Exporting flows in NetFlow Analyzer is a simple process that involves adding credentials, followed by selecting interfaces(for Predefined Flow Export), selecting/adding flow export commands, and finally executing the commands. NetFlow Analyzer allows you to export flows using two methods,
You can access the export flow page by,
1: Navigating to Settings → NetFlow → Discovery → Export Flow.
2: Alternatively, navigate to Inventory, and click the Add icon in the Devices tab to access the Flow Export page.
3: You can also access to the Export Flow page from the Getting Started page.
NetFlow Analyzer requires both SNMP(for Predefined Flow Export) and Telnet or SSH credentials for flow export. SNMP fetches the device and its interfaces, while SSH or Telnet execute the flow export commands. Devices can be identified using either the Hostname or IP address.
Follow the steps below to export flows from the NetFlow Analyzer.
Step 1: Enter the Hostname or IP address. You can add SNMP credentials by clicking the add icon next to Select SNMP credentials or by selecting one of the existing SNMP credentials. Select SSH or Telnet as the protocol type.
Enter the User Name, Password, Prompt, Enable Command, Enable User Name, Enable Password, and Enable Prompt.
You can add additional parameters like Telnet/SSH port, Timeout (sec), Login Prompt, Password Prompt, Login Prefix Prompt, Login Prefix, Enable UserName Prompt, and Enable Password Prompt, by checking the Additional Parameters checkbox.
Once you've entered the credentials, click Next to test the connection using Ping, Test SNMP, and Test Telnet/SSH to move to the next page.
Step 2: The Source interface and Device type will be automatically selected. Verify the source interface and device type and commands, and click Export Flow.
NetFlow Analyzer supports all major flow formats from various vendors. If NetFlow Analyzer doesn't have predefined flow export commands for your particular device model or if you want to use a different set of commands, you can manually enter and execute them by clicking Export Flow.
Step 1: Enter the Hostname or IP address, select the Protocol type.
You can add additional parameters such as Telnet/SSH port by checking the Additional Parameters checkbox.
Step 2: Once you've entered the credentials, click Open Terminal to test the connection using Ping and to move to the next page.
Step 2: Check the Show flow export command box to view the list of devices and their commands in our database. You can manually enter flow export configuration commands for your device or copy the commands displayed, and execute them.
Once the flow is exported, you can view the added devices in the Flow Analysis tab in the Inventory.
