|The HP 3500 Switch Series consists of advanced intelligent-edge switches, available in 24-port and 48-port fixed-port models. The foundation for these switches is a purpose-built, programmable HP 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 10GbE connectivity (CX4, X2, and SFP+) on Gigabit Ethernet switches, the 3500 Switch Series offers excellent investment protection, flexibility, and scalability, as well as ease of deployment, operation, and maintenance.|
- OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) and control (routing decision) paths.
- 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. Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers. Traffic prioritization: allows real-time traffic classification into eight priority levels mapped to eight queues. Bandwidth shaping: Port-based rate limiting: provides per-port ingress-/egress-enforced increased bandwidth. Classifier-based rate limiting: uses an access control list (ACL) to enforce increased bandwidth for ingress traffic on each port. Reduced bandwidth: provides per-port, per-queue egress-based reduced bandwidth. 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.
- 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. RMON, XRMON, and sFlow v5: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events. IEEE 802.1AB Link Layer Discovery Protocol (LLDP): advertises and receives management information from adjacent devices on a network, facilitating easy mapping by network management applications. Uni-Directional Link Detection (UDLD): monitors a 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. Management simplicity: common software features and CLI implementation across all ProVision-based switches (including the zl and yl switches).
- 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. IEEE 802.3at Power over Ethernet Plus (PoE+): provides up to 30 W per port to IEEE 802.3 for devices that use PoE/PoE+, such as video IP phones, IEEE 802.11n wireless access points, and advanced pan/zoom/tilt security cameras. Prestandard PoE support: detects and provides power to prestandard PoE devices; see list of supported devices in the product FAQs at www.hp.com/networking. Jumbo frames: on Gigabit Ethernet and 10-Gigabit Ethernet ports, jumbo frames allow high-performance remote backup and disaster-recovery services. Auto-MDIX: provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports.
- 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. Selectable queue configurations: allows for increased performance by selecting the number of queues and associated memory buffering that best meet the requirements of the network applications.
- Virtual Router Redundancy Protocol (requires Premium License): allows groups of two routers to dynamically back each other up to create highly available routed environments. IEEE 802.1s Multiple Spanning Tree Protocol: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; encompasses IEEE 802.1D Spanning Tree Protocol and IEEE 802.1w Rapid Spanning Tree Protocol. IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 144 trunks, each with up to eight links (ports) per trunk. Distributed trunking: enables loop-free and redundant network topology without using Spanning Tree Protocol; allows a server or switch to connect to two switches using one logical trunk for redundancy and load sharing. Uplink Failure Detection: provides active-standby network path redundancy for servers that are configured for active-standby NIC teaming.
- 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. HP switch meshing: dynamically load-balances across multiple active redundant links to increase available aggregate bandwidth. VLAN support and tagging: supports the IEEE 802.1Q standard and 2,048 VLANs simultaneously. IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs. GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment o
