MikroTik RouterOS supports diverse Ethernet interfaces from 10Mbps to 100Gbps, including copper and fiber options with combo interfaces. It enables control over link speed, duplex mode, auto-negotiation, and SFP/QSFP interface configuration with manual advertise settings for precise link mode specification.
Loop Protect prevents Layer2 loops by detecting and disabling interfaces receiving their own loop-protect packets, with configurable intervals and disable times. It supports Ethernet, VLAN, EoIP, and VxLAN interfaces, though (R/M)STP is recommended for bridges.
