It delivers maximum wire-speed Layer 2 forwarding capability across all standard Ethernet frames, handling IPv4, IPv6, and non-IP traffic seamlessly. ### Core & Advanced Features Beyond standard managed switch capabilities, SwOS offers a robust suite of networking features: * **VLAN Management:** Full configuration support for complex VLAN setups, including access and trunking ports. * **Traffic Control:** Advanced broadcast storm control, bandwidth limiting, and port-to-port forwarding settings. * **Monitoring & Mirroring:** Ingress/egress traffic mirroring along with real-time port-level statistics. * **Security & Filtering:** A granular Access Control List (ACL) engine capable of matching traffic by MAC, IP, and port-level rules. * **Hardware Offloading:** Direct hardware-driven manipulation of specific MAC and IP header fields on supported device models. :::note Management Limitation SwOS is configured exclusively through a standard web browser (HTTP) over IPv4. It does not support command-line interface (CLI) access via serial console/SSH, API access, WinBox, or other alternative management protocols. :::
