Dual Operating Systems for Maximum Flexibility

RouterOS

RouterOS transforms the switch into a powerful Layer 3 networking platform, supporting advanced routing, VLANs, firewall capabilities, QoS, scripting, monitoring, and numerous enterprise networking features.

It is ideal for network professionals requiring extensive control over their infrastructure.

SwOS

For organizations seeking a simpler switching experience, SwOS provides an intuitive web interface focused on switch management.

Administrators can easily configure:

• VLANs
• Port forwarding
• Link aggregation
• Traffic monitoring
• Access Control Lists (ACLs)
• Port mirroring
• Bandwidth control

The Dual Boot feature allows you to select the operating system best suited to your deployment without purchasing additional hardware.
