Support Output File (supout.rif)

Support Output File (supout.rif)

Summary

Sub-menu: /system Command: /system sup-output

The supout.rif file is a binary diagnostic snapshot of your RouterOS device. MikroTik Support uses this file to diagnose issues quickly without needing direct router access. The file captures router configuration, log data, routing tables, interface statistics, and other operational details.

Note

The file does not contain sensitive information such as router passwords.

What Is Included

The support output file contains a comprehensive snapshot of the router’s state at the time of generation, including:

• Full device configuration (equivalent to /export)
• System logs
• Routing tables and ARP cache
• Interface status and statistics
• Active connections
• Installed packages and their versions
• Resource usage (CPU, memory, disk)
• Hardware information

This data allows MikroTik Support to reproduce your configuration and diagnose issues without requiring access to the live device.

Generating a Support Output File

Console

/system sup-output name=supout.rif

The file is saved to the router’s root file storage and is accessible via WinBox Files or FTP.

On physical RouterOS hardware that has a /flash partition (e.g., RB series with NAND flash), you can save directly to flash storage:

/system sup-output name=flash/supout.rif

Note

CHR (Cloud Hosted Router) has no /flash partition. Using name=flash/supout.rif on CHR returns failure: bad file name. On CHR, use the default path (name=supout.rif) and retrieve the file via FTP or WinBox Files.

WinBox

1. Open WinBox and connect to your router.
2. Click Make Supout.rif (visible in the toolbar or top menu).
3. The file appears in the Files list.
4. Right-click the file and select Download, or drag it to your desktop.

WebFig

1. Open WebFig in a browser.
2. Click Make Supout.rif.
3. Click Download to save the file to your computer.

Submitting to MikroTik Support

When opening a support ticket at help.mikrotik.com, attach the supout.rif file to provide MikroTik Support with full device context. This significantly reduces the time required to diagnose and resolve issues.

Viewing with the Online Supout Viewer

MikroTik provides an online viewer to inspect the contents of a supout.rif file:

1. Log in to your MikroTik account at mikrotik.com.
2. Click Supout.rif viewer in the left column.
3. Upload your supout.rif file.
4. Browse the sections of the file — configuration, logs, interfaces, and more.

The viewer parses the binary file into human-readable sections, making it useful for self-diagnosis as well as support escalation.

Automatic Support Output (autosupout.rif)

RouterOS generates a support output file automatically when a software failure (crash) occurs. This file is named autosupout.rif and is stored in the router’s root filesystem.

When a new crash occurs, the previous autosupout.rif is renamed to autosupout.old.rif before the new file is written. This preserves one generation of history.

This behavior is controlled by the Watchdog subsystem:

Property	Default	Description
automatic-supout	yes	Generate autosupout.rif on software failure
auto-send-supout	no	Email the file after automatic generation
send-email-to	—	Recipient address for automatic email
send-smtp-server	—	SMTP server (falls back to /tool e-mail settings)
send-email-from	—	Sender address (falls back to /tool e-mail settings)

Note

Watchdog reboots (triggered by ping watchdog or the watchdog timer) are not software failures and do not generate autosupout.rif.

Configure Automatic Email Delivery

To automatically email the support file to yourself or your support team on any software crash:

/system watchdog set auto-send-supout=yes \
    [email protected] \
    send-smtp-server=192.0.2.1

Verify the configuration:

/system watchdog print

Expected output:

      watch-address: none
     watchdog-timer: yes
      no-ping-delay: 5m
   automatic-supout: yes
   auto-send-supout: yes
   send-smtp-server: 192.0.2.1
      send-email-to: [email protected]

Common Use Cases

After an Unexpected Reboot

If the router rebooted unexpectedly, check whether autosupout.rif is present:

/file print where name~"supout"

If found, download and inspect it with the supout viewer to identify the crash cause before opening a support ticket.

Before Contacting Support

Generate a fresh supout.rif immediately after reproducing the problem — logs and connection tables are time-sensitive:

/system sup-output name=supout.rif

Then download and attach the file to your support ticket.

Storage Considerations

On physical routers with a /flash partition, generate the file directly to flash storage:

/system sup-output name=flash/supout.rif

This path is not available on CHR. On CHR, use the default path and download via FTP or WinBox Files.

Remove old files when no longer needed:

/file remove supout.rif
