Features and benefits

Quality of Service (QoS)

• Layer 4 prioritization: enables prioritization

based on TCP/UDP port numbers

• Traffic prioritization (IEEE 802.1p): allows

real-time traffic classification into eight priority levels
mapped to eight queues

• 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: sets per-port ingress enforced

maximums and per-port, per-queue guaranteed
minimums

Connectivity

• Auto-MDIX: automatically adjusts for

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

• IPv6:

– IPv6 host: allows the switches to be managed

and deployed at the edge of an IPv6 network

– Dual stack (IPv4/IPv6): provides a 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/tilt/zoom 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/neworking/support

• Single IP address management: provides

single IP address management for a virtual stack of
up to 16 switches

Resiliency and high availability

• External redundant power supply: provides

high reliability

• 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

• IEEE 802.1s Multiple Spanning Tree: provides

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

Manageability

• Dual flash images: provides independent

primary and secondary operating system files for
backup while upgrading

• Friendly port names: allow assignment of

descriptive names to ports

• Find-Fix-Inform: finds and fixes common network

problems automatically, then informs administrator

• Multiple configuration files: allow multiple

configuration files to be stored to a flash image

• Software updates: free downloads from the

Web

• RMON, XRMON, and sFlow: provide

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

• Troubleshooting: ingress and egress port

monitoring enable network problem solving

Layer 2 switching

• VLANs: provide support for 512 VLANs and

4,094 VLAN IDs

• Jumbo packet support: supports up to

9220-byte frame size to improve the performance of
large data transfers

• IEEE 802.1v protocol VLANs: isolate select

non-IPv4 protocols automatically into their own
VLANs

Layer 3 routing

• Static IP routing: provides manually configured

routing; includes ECMP capability

• Routing Information Protocol (RIP): provides

RIPv1 and RIPv2 routing
