Resiliency And High Availability; Layer 2 Switching - HP E5400 zl Series Datasheet

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
• Selectable queue configurations: allow you to
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: 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 60 trunks, each with up to 8 links
(ports) per trunk
•
NEW 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
• Optional redundant power supply (HP
E5400 series): provides uninterrupted power and
allows hot-swapping of the redundant power
supplies when installed
• Hot-swappable modules (E5400 zl series):
permits modules, mini-GBICs, and power supplies in
a redundant power supply configuration to be
added or swapped without interrupting the network
• Sparing simplicity: HP zl-common accessories
(interface modules, power supplies)

Layer 2 switching

• 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 2,048 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
• 802.1ad QinQ: increases the scalability of an
Ethernet network by providing a hierarchical
structure; connects multiple LANs on high-speed
campus or metro network
•
NEW MAC-based VLAN: provides granular
control and security; uses RADIUS to map MAC
address/user to specific VLAN's. (requires v2
modules)
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
• 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
Layer 3 routing
• Static IP routing: provides manually configured
routing for both IPv4 and IPv6 networks
• Routing Information Protocol (RIP): provides
RIPv1 and RIPv2 routing
• OSPF: provides OSPFv2 for IPv4 routing and
OSPFv3 for IPv6 routing
Security
• Access control lists (ACLs): provide filtering
based on the IP field, source/destination IP
address/subnet, and source/destination TCP/UDP
port number on a per-VLAN or per-port basis
