SFP port Supports auto-media-detection, auto-failover, and remote
fault indication (RFI), as described in the IEEE 802.3ah

See the Cisco 892F data sheet for a list of supported SFPs.
1. FE = Fast Ethernet.
2. MDI = media-dependent interface in normal mode.
3. MDIX = media-dependent interface in crossover mode.
4. GE = Gigabit Ethernet.
5. MDI = media-dependent interface in normal mode.
