HPE J8772B HPE E4202-72 vl Switch Managed

The HP 42 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 1/1, 1/1/1, and 1-Gigabit scalable solutions that integrate easily into any network.

Quality of Service (QoS)

• Traffic prioritization (IEEE 82.1p): allows real-time traffic classification into eight priority levels mapped to eight queues

Management

• 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

Connectivity

• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 1/1 and 1/1/1 ports

Performance

• 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

Resiliency and high availability

• IEEE 82.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 6 trunks, each with up to eight links (ports) per trunk

Manageability

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

Layer 2 switching

• VLAN support and tagging: supports IEEE 82.1Q (4,94 VLAN IDs) and 256 VLANs simultaneously
