Quality of Service (QoS)

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
Layer 4 prioritization ? enables prioritization based on TCP/UDP port numbers
Traffic prioritization (IEEE 802.1p) ? allows real-time traffic classification with support for eight priority levels mapped to four queues

Connectivity

Dual-personality functionality ? four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, and -LH, or 100-FX

Resiliency and high availability

IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking ? support up to 24 trunks, each with up to 8 links (ports) per trunk
IEEE 802.1s Multiple Spanning Tree ? provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w
Optional redundant power supply ? provides uninterrupted power (provided by HP 600 RPS/EPS)
