Features and benefits
Quality of Service (QoS)
•
Traffic prioritization (IEEE 802.1p): allows
real-time traffic classification into eight priority levels
mapped to eight queues
•
Layer 4 prioritization: enables prioritization
based on TCP/UDP port numbers
•
Class of Service (CoS): sets the IEEE 802.1p
priority tag based on IP address, IP Type of Service
(ToS), Layer 3 protocol, TCP/UDP port number,
source port, and DiffServ
•
Rate limiting: per-port ingress enforced
maximums
Connectivity
•
10 Gbps Ethernet connectivity: up to four
optional and flexible 10-Gigabit ports (CX4 and/or
SFP+), with optional interconnect kit for
short-distance connectivity
•
IPv6:
– IPv6 host: allows the switches to be managed
and deployed at the edge of IPv6 networks
– Dual stack (IPv4/IPv6): provides transition
mechanism from IPv4 to IPv6; supports
connectivity for both protocols
– MLD snooping: forwards IPv6 multicast traffic to
the appropriate interface; prevents IPv6 multicast
traffic from flooding the network
•
IEEE 802.3af Power over Ethernet (PoE):
provides up to 15.4 W per port to IEEE
802.3af-compliant PoE-powered devices such as IP
phones, wireless access points, and security
cameras
•
IEEE 802.3at Power Over Ethernet Plus:
provides up to 30 W per port to IEEE 802.3 for
PoE/PoE+ powered devices such as video IP
phones, IEEE 802.11n wireless access points, and
advanced pan/zoom/tilt security cameras
•
Pre-standard PoE support: detects and
provides power to pre-standard PoE devices; see list
of supported devices in the product FAQ at
www.hp.com/networking/support
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all 10/100
and 10/100/1000 ports
•
Dual-personality functionality: includes four
10/100/1000 ports or SFP slots for optional fiber
connectivity such as Gigabit-SX, -LX, -LH, 100-FX,
100-BX, and 1000-BX
•
Single IP Address Management: single IP
address management for a virtual stack of up to 16
switches
Performance
•
High-performance architecture: 128 Gbps
switching fabric with up to 95 Mpps (24-port
switches) and 176 Gbps switching fabric with up to
131 Mpps (48-port switches)
•
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
•
IEEE 802.1s Multiple Spanning Tree: provides
high link availability in multiple VLAN environments
by allowing multiple spanning trees; provides
legacy support for IEEE 802.1d and IEEE 802.1w
•
IEEE 802.3ad Link Aggregation Protocol
(LACP) and HP port trunking: support up to 24
trunks, each with up to 8 links (ports) per trunk
•
Optional redundant power supply: supplies
backup power in case of power failure (note: HP
E620 Redundant/External Power Supply provides
only RPS functionality)
Manageability
•
RMON, XRMON, and sFlow: provide
advanced monitoring and reporting capabilities for
statistics, history, alarms, and events
•
Uni-Directional Link Detection (UDLD):
monitors a link between two switches and blocks the
ports on both ends of the link if the link goes down
at any point between the two devices
•
Command authorization: leverages RADIUS to
link a custom list of CLI commands to an individual
network administrator's login; also provides an audit
trail
•
Dual flash images: provides independent
primary and secondary operating system files for
backup while upgrading
•
Multiple configuration files: allow multiple
configuration files to be stored to a flash image
•
Friendly port names: allow assignment of
descriptive names to ports
•
Find-Fix-Inform: finds and fixes common network
problems automatically, then informs administrator
•
Software updates: free downloads from the
Web
