ProCurve Switch 5400zl/3500yl Series

•Selectable queue configurations: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications

Resiliency and high availability

•Virtual Router Redundancy Protocol (requires Premium License): VRRP 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 ProCurve trunking: support up to 36 trunks, each with up to 8 links (ports) per trunk; trunking across modules is supported

•Hot-swappable modules (5400zl series): permits modules, mini-GBICs, and power supplies in a redundant power supply configuration to be added or swapped without interrupting the network

•Optional redundant power supply (5400zl series): provides uninterrupted power and allows hot-swapping of the redundant power supplies when installed

•Sparing simplicity: ProCurve zl-common accessories (interface modules, power supplies)

Layer 2 switching

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

•ProCurve 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 of VLANs

Layer 3 services

•UDP helper function: UDP broadcasts can be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevent server spoofing for UDP services such as DHCP

•Loopback interface address: defines an address in RIP and OSPF that can always be reachable, improving diagnostic capability

Layer 3 routing

•Static IP routing: provides manually configured routing

•RIP: provides RIPv1 and RIPv2 routing at media speed

•OSPF (requires Premium License): includes host-based ECMP to provide link redundancy/scalable bandwidth and NSSA

Security

NEW USB Secure Autorun* (requires ProCurve Manager Plus): deploys, diagnoses, and updates switch using USB flash drive; works with secure credential to prevent tampering

•Switch CPU protection: provides automatic protection against malicious network traffic trying to shut down the switch

∗Availability targeted for the second quarter of 2008.
