Features and benefits

Performance

• Architecture: up to 76.8 Gbps crossbar switching

fabric provides wire-speed intra- and inter-module
switching with up to 48 million pps throughput built
on ProCurve custom-designed ASIC technology

Resiliency and high availability

• Router redundancy (XRRP): allows groups of

two routers to dynamically back each other up to
create highly available routed environments

• IEEE 802.1s Multiple Spanning Tree: provides

high link availability in multiple VLAN environments
by allowing multiple spanning trees

• IEEE 802.1w Rapid Convergence Spanning

Tree Protocol: increases network uptime through
faster recovery from failed links

• IEEE 802.3ad Link Aggregation Control

Protocol (LACP) and ProCurve trunking:
support up to 60 trunks, each with up to 8 links
(ports) per trunk; trunking across modules is
supported

• Hot-swappable modules: permit modules,

mini-GBICs, and one of the power supplies in a
redundant power supply configuration to be added
or swapped without interrupting the network

• Optional redundant power supply: provides

uninterrupted power; allows hot-swapping of one of
the two supplies when installed

Manageability

• User-driven port configuration support:

switch port configuration responds to RADIUS-stored
user attributes for QoS and rate limiting when that
user authenticates; these attributes are then
determined by the user, not the switch port

• RMON, XRMON, and sFlow: provide

advanced monitoring and reporting capabilities for
statistics, history, alarms, and events

• IEEE 802.1AB Link Layer Discovery Protocol

(LLDP): automated device discovery protocol for
easy mapping by network management applications

• Friendly port names: allow assignment of

descriptive names to ports

• Auto-MDIX: automatically adjusts for

straight-through or crossover cables on all
10/100/1000 ports

• Dual flash images: provides independent

primary and secondary OS and configuration files
for backup while upgrading or fine-tuning the switch
configuration

• Multiple configuration files: allow a config file

to be stored for each flash image

• Troubleshooting: ingress/egress port monitoring

enables network problem-solving

• Custom banner: displays security policy when

users log in to the switch

Layer 2 switching

• ProCurve switch meshing: dynamically

load-balances across multiple active redundant links
to increase available aggregate bandwidth

• VLAN support and tagging: support complete

IEEE 802.1Q (4,096 VLAN IDs) and 256 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

Layer 3 routing

• Layer 3 IP routing: provides routing of IP at

media speed; supports static routes, RIP, RIPv2, and
OSPF

• OSPF-ECMP: enables multiple equal-cost links in

OSPF environment to increase link redundancy and
scale bandwidth

Security

• Virus throttling: detects traffic patterns typical of

WORM-type viruses and either throttles or entirely
prevents the ability of the virus to spread across the
routed VLANs, without requiring external appliances

• ICMP throttling: defeats ICMP denial-of-service

attacks by enabling any switch port to automatically
throttle ICMP traffic
