Power Efficiency

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

• MAC table Up to 8000 MAC addresses

Discovery

• Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDPMED 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 (available April 2011)
