• IEEE 802.3at PoE+
Provides up to 30 W per port, allowing support of the latest PoE+-capable devices such as IP
phones, wireless access points, and security cameras as well as any IEEE 802.3af-compliant
end device; and mitigates the cost of additional electrical cabling and circuits that would
otherwise be necessary in IP phone and WLAN deployments
• Pre-standard PoE support
Detects and provides power to pre-standard PoE devices
• Dual-personality functionality
Includes four 10/100/1000 ports or SFP slots for optional ber connectivity such as Gigabit SX,
LX, and LH or 100 FX
Performance
• Energy-ecient design
– 80 PLUS Silver Certied power supply
Increases power eciency and savings
– Energy-ecient Ethernet (EEE) support
Reduces power consumption in accordance with IEEE 802.3az
• HP ProVision ASIC architecture
Is designed with the latest ProVision ASIC, providing very low latency, increased packet
buering, and adaptive power consumption
• Selectable queue congurations
Increases performance by selecting the number of queues and associated memory buering
that best meet the requirements of the network applications
Software-dened networking (SDN)
• NEW OpenFlow
Is a key technology that enables SDN by allowing separation of the data (packet forwarding)
and control (routing decision) paths
Convergence
• IP multicast snooping (data-driven IGMP)
Mitigates ooding of IP multicast trac automatically
• Media endpoint discovery (MED) enabled by the link-layer discovery protocol (LLDP)
Denes a standard extension of LLDP that stores values for parameters such as QoS and VLAN
to automatically congure network devices such as IP phones
• IEEE 802.1ab LLDP
Facilitates easy mapping, using network management applications with the LLDP automated
device discovery protocol
• PoE and PoE+ allocations
Support multiple methods—automatic, IEEE 802.3at dynamic, LLDP-MED ne grain, IEEE
802.3af device class, or user specied—to allocate and manage PoE/PoE+ power for more
ecient energy use
• Local MAC authentication
Assigns attributes such as VLAN and QoS, using a locally congured prole that can be a list of
MAC prexes
