Features and benefits

Quality of service (QoS)

• L4 prioritization

Enables prioritization based on TCP/UDP port numbers

• Traffic prioritization (IEEE 802.1p)

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

• Class of service (CoS)

Sets the IEEE 802.1p priority tag based on the IP address, IP type of service (ToS), L3 protocol,

TCP/UDP port number, source port, and DiffServ

• Rate limiting

Establishes per-port ingress-enforced maximums and per-port, per-queue minimums

Connectivity

• Auto-MDIX

Provides automatic adjustments 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; and supports connectivity for both

protocols

– MLD snooping

Forwards IPv6 multicast traffic to the appropriate interface; and helps prevent 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 PoE+

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 (refer to the list of supported devices

in the product FAQs, which can be accessed at hp.com/networking/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-control protocol (LACP) and HP port trunking

Support up to 24 trunks, each with up to 8 links (ports) per trunk

• Multiple spanning tree protocol (STP) and IEEE 802.1s

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

trees; and provides legacy support for IEEE 802.1d and IEEE 802.1w
