Cable length detection | Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10 m. |
Jumbo frames | Frame sizes up to 10 KB supported on 10/100 and Gigabit Ethernet interfaces (9 KB for SG200-08 and SG200-08P) |

Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDP-MED extensions | LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices, which store the data in an MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones. |
Cisco Discovery Protocol | The switch advertises itself using the Cisco Discovery Protocol. It also learns the connected device and its characteristics via this protocol. |
Auto Smartports | Automatically applies the intelligence delivered through the Smartports roles to the port based on the devices discovered over Cisco Discovery Protocol or LLDP-MED. This capability facilitates zero-touch deployments. |
Bonjour | The switch advertises itself using the Bonjour protocol |
