The HP E5400 zl Switch Series consists of advanced intelligent switches in the HP E-Series product-line. The E5400 zl series includes 6-slot and 12-slot chassis and associated zl modules and bundles. The foundation for all of 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 10/100, Gigabit Ethernet and 10 Gigabit Ethernet interfaces, choice of PoE+ & Non-PoE, integrated layer 3 features and HP allianceONE Solutions, the E5400 zl 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 E8200, E6200, E5400, or E3500 switch anywhere on the network

Connectivity
• IEEE 802.3az Energy Efficient Etherent: Lowers power consumption in periods of low link usage. (Supported on v2 zl 10/100/1000 & 10/100 modules)

Performance
• High-speed/capacity architecture: 1 Tbps crossbar switching fabric provides intra-module and inter-module switching with 585.6 million pps throughput on the purpose-built ProVision ASICs

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

Layer 2 switching
• HP's switch meshing: dynamically load-balances across multiple active redundant links to increase available aggregate bandwidth

Layer 3 services
• 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
