MikroTik RouterOS

MikroTik RouterOS supports flow-based network traffic analysis using Traffic Flow, which is similar to IPFIX or NetFlow. To configure Traffic Flow on a MikroTik RouterOS device, follow these steps:

Access the router CLI​

Connect to your MikroTik router via SSH or a console cable. If connecting via SSH, use a tool like PuTTY or the built-in SSH client in your terminal, and enter the router's IP address, username, and password to log in.

Enable Traffic Flow​

Enter the following command to enable Traffic Flow on the router:

/ip traffic-flow set enabled=yes

Configure Traffic Flow settings​

To configure Traffic Flow settings, including the interface(s) to monitor and the IP address and port of the remote flow collector, use the following commands:

/ip traffic-flow target add address=x.x.x.x:yyyy version=10
/ip traffic-flow interfaces add interface=INTERFACE_NAME

Replace x.x.x.x with the IP address of the Unified Flow Collector, yyyy with the desired port number for the Unified Flow Collector (e.g., 4739 for IPFIX), and INTERFACE_NAME with the name of the interface you want to monitor (e.g., ether1).

Optional​

Configure Traffic Flow cache settings: If you want to customize the cache settings for Traffic Flow, such as timeouts and cache size, use the following command:

/ip traffic-flow set cache-entries=4096 active-flow-timeout=1m inactive-flow-timeout=15s

Adjust the values for cache-entries, active-flow-timeout, and inactive-flow-timeout as needed.

Save the configuration​

To save your configuration changes, use the following command:

/system configuration save

Verify the configuration​

To verify that Traffic Flow is configured correctly and exporting flow data, use the following command:

/ip traffic-flow print

This command should display the Traffic Flow settings you just configured.

Once you have completed these steps, your MikroTik RouterOS device will start exporting flow data using Traffic Flow (similar to IPFIX) to the specified ElastiFlow Unified Flow Collector. Make sure the Unified Flow Collector is set up to receive and process the exported data for analysis and monitoring purposes.
