The HP 3500 Switch Series consists of the most advanced intelligent edge switches in the HP networking product line. The 3500 series includes 24-port and 48-port fixed-port switches. The foundation for all these switches is a purpose-built, programmable ProVision ASIC that allows the most demanding networking features, such as Quality of Service (QoS) and security, to be implemented in a scalable yet granular fashion. With a variety of Gigabit Ethernet and 10/100 interfaces; integrated PoE+, PoE, and non-PoE options; and versatile 10-GbE connectivity (CX4, X2, and SFP+) on Gigabit Ethernet switches, the 3500 switches offer excellent investment protection, flexibility, and scalability, as well as ease of deployment, operation, and maintenance.

Quality of Service (QoS)
• Advanced classifier-based QoS: classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a per-port or per-VLAN basis

Management
• Remote intelligent mirroring: mirrors selected ingress/egress traffic based on ACL, port, MAC address, or VLAN to a local or remote HP 8200 zl, 6600, 6200 yl, 5400 zl, or 3500 switch anywhere on the network

Connectivity
• IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras

Performance
• High-speed/capacity architecture: up to 153.6 Gbps crossbar switching fabric provides intra- and inter-module switching with up to 111.5 million pps throughput on the purpose-built ProVision ASICs

Resiliency and high availability
• Virtual Router Redundancy Protocol (requires Premium License): allows groups of two routers to dynamically back each other up to create highly available routed environments

Layer 2 switching
• IEEE 802.1ad Q-in-Q (requires Premium License): increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on a high-speed campus or metro network

Layer 3 services
• User Datagram Protocol helper function: allows User Datagram Protocol (UDP) broadcasts to be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevents server spoofing for UDP services such as DHCP
