Quality of Service (QoS)

Rate limiting ? per-port ingress enforced maximums
Layer 4 prioritization ? enables prioritization based on TCP/UDP ports
Traffic prioritization (IEEE 802.1p) ? allows real-time traffic classification into eight priority levels mapped to eight queues
Class of Service (CoS) ? sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ

Performance

160 Gbps backplane with 119 mpps ? unprecedented bandwidth for low-latency throughput
Selectable queuing configurations ? increase performance by selecting the queuing configuration that best meets the requirements of network applications
Jumbo frames ? on Gigabit and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services

Manageability

sFlow (RFC 3176) ? wire-speed traffic accounting and monitoring
RMON and XRMON ? provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Stacking capability ? single IP address management for a virtual stack of up to 16 switches
