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
IEEE 802.1ad Q-in-Q (requires Premium
NEW
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
USB Secure Autorun* (requires ProCurve
NEW
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.
