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
