Power Efficiency

Energy Detect Automatically turns off power on Gigabit Ethernet RJ-45 port when detecting link down. Active mode is resumed without loss of any packets when the switch detects the link up
Cable length detection Adjusts the signal strength based on the cable length. Reduces the power consumption for cables shorter than 10m.

Discovery

Bonjour The switch advertises itself using the Bonjour protocol
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 that store the data in a 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.
