Switching capacity: 38.4 Gbit/s, Throughput: up to 22.4 million pps, Maximum data transfer rate: 0.1 Gbit/s. Supported network protocols: RFC 783 TFTP; RFC 1542 BootP; RFC 768 UDP; RFC 792 ICMP; RFC 793 TCP; RFC 826 ARP; RFC 2030 SNTP; RF. Safety: CSA 22.2 No. 950; UL 60950; EN 60950, Electromagnetic compatibility: FCC Class A; VCCI Class A; EN 55022/CISPR 22 Class A; CISPR 22 Class A; EN 55024; IEC/EN 61000-3-2;

The HP 4200 vl Switch Series consists of modular chassis that provide a flexible, cost-effective LAN solution as an alternative to stackable switches. These switches offer a proven chassis form factor with high quality and reliability in 10/100, 10/100/1000, and 10-Gigabit scalable solutions that integrate easily into any network.

Quality of Service (QoS)
\n• Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues

\nManagement
\n• Uni-Directional Link Detection (UDLD): monitors cable between two switches and shuts down the ports on both ends if the cable is broken, turning the bidirectional link into a unidirectional one; this prevents network problems such as loops

\nConnectivity
\n• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports

\nPerformance
\n• Architecture: up to 76.8 Gbps crossbar switching fabric provides wire-speed intra- and inter-module switching with up to 48 million pps throughput built on HP custom-designed ASIC technology

\nResiliency and high availability
\n• IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 60 trunks, each with up to eight links (ports) per trunk

\nManageability
\n• sFlow (RFC 3176): wire-speed traffic accounting and monitoring

\nLayer 2 switching
\n• VLAN support and tagging: supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously\n
