Hewlett Packard 3500

The HP E3500 Switch Series consists of the most advanced intelligent edge switches in the HP Networking product line. The E3500 series includes 24-port and 48-port fixed-port switches

Key Feature

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 maximum bandwidth. Classifier-based rate limiting: uses access control list (ACL) to enforce maximum bandwidth for ingress traffic on each port. Guaranteed minimum: provides per-port, per-queue egress-based guaranteed minimum 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 E8200 zl, E6600, E6200 yl, E5400 zl, or E3500 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): automated device discovery protocol provides easy mapping by network management applications
•    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 bi-directional link into uni-directional; this prevents network problems such as loops
•    Management simplicity: provides HP E-Series-common networking features and CLI implementation (common across HP E8200 zl, E6600, E6200 yl, E5400 zl, and E3500 switches)
•    IPv6: IPv6 host: enables switches to be managed and deployed at the IPv6 network’s edge. Dual stack (IPv4 and IPv6): transitions from IPv4 to IPv6, supporting connectivity for both protocols . MLD snooping: forwards IPv6 multicast traffic to the appropriate interface. IPv6 ACL/QoS: supports ACL and QoS for IPv6 network traffic, preventing traffic flooding. IPv6 routing: supports static and OSPFv3 routing protocols.
•    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 PoE-/PoE+-powered devices 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 and 10-Gigabit ports, allow high-performance remote backup and disaster-recovery services
•    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: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your 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
•    Server-to-switch distributed trunking: allows a server to connect to two switches with one logical trunk that consists of multiple physical connections; enables load-balancing and increases resiliency
•    IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 60 trunks, each with up to 8 links (ports) per trunk
•    IEEE 802.1ad QinQ (requires Premium License): increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on high-speed campus or metro network
•    HP’s 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 2048 VLANs simultaneously
•    IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs
•    GARP VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs
•    User Datagram Protocol (UDP) helper function: allows 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
•    Loopback interface address: defines an address in Routing Information Protocol (RIP) and OSPF that can always be reachable, improving diagnostic capability
•    Route maps: provide more control during route redistribution; allow filtering and altering of route metrics
