Key Features

Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues

Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers

Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue minimums

Large buffers: provide graceful congestion management

Auto-MDIX: provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports

IEEE 802.3at Power over Ethernet (PoE+): provides up to 30 W per port that allows support of the PoE+-capable devices

Energy-efficient design: high-efficiency power supplies: 80 PLUS Silver certified power supply increases power savings

OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data and control paths
