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: 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
• Server-to-switch distributed trunking: allows
a server to connect to two switches with one logical
trunk that consists of multiple physical connections;
enables load-balancing and increases resiliency
• 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
• 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
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
•
NEW
Route maps: provide more control during
route redistribution; allow filtering and altering of
route metrics
Layer 3 routing
•
NEW
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
• Multiple user authentication methods:
– IEEE 802.1X users per port: provides
authentication of multiple IEEE 802.1X users per
port; prevents user "piggybacking" on another
user's IEEE 802.1X authentication
– Web-based authentication: authenticates
from Web browser for clients that do not support
IEEE 802.1X supplicant; customized remediation
can be processed on an external Web server
– MAC-based authentication: client is
authenticated with the RADIUS server based on
client's MAC address
– Concurrent IEEE 802.1X, Web, and MAC
authentication schemes per port: switch
port will accept up to 32 sessions of IEEE 802.1X,
Web, and MAC authentications
