Features and benefits
Quality of Service (QoS)
•
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
•
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 four queues
Connectivity
•
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
•
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
•
Gigabit uplink connectivity: two
10/100/1000Base-T ports and two mini-GBIC ports
for connectivity such as Gigabit Ethernet (SX, LX, LH,
and 1000Base-T) and 100Base-FX
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all 10/100
ports
•
Jumbo packet support: supports up to
9216-byte frame size to improve performance of
large data transfers
•
Pre-standard PoE support: detects and
provides power to most of Cisco's pre-standard PoE
devices; see list of support devices in product's FAQ
on www.hp.com/networking
Resiliency and high availability
•
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; provides
legacy support for IEEE 802.1d and IEEE 802.1w
•
Optional redundant power supply: provides
uninterrupted power (provided by HP E600
RPS/EPS)
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 individual
network administrator's login; also provides an audit
trail
•
Multiple configuration files: allow multiple
configuration files to be stored to a flash image
•
Dual flash images: provides independent
primary and secondary operating system files for
backup while upgrading
•
Single IP Address Management: single IP
address management for a virtual stack of up to 16
switches
•
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
•
Troubleshooting: ingress and egress port
monitoring enable network problem solving
Layer 2 switching
•
VLAN support and tagging: supports IEEE
802.1Q (4,094 VLAN IDs) and 256 VLANs
simultaneously
•
GARP VLAN Registration Protocol: allows
automatic learning and dynamic assignment of
VLANs
•
IEEE 802.1v protocol VLANs: isolate select
non-IPv4 protocols automatically into their own
VLANs
Layer 3 routing
•
Basic IP routing: enables automatic routing to the
connected VLANs and up to 16 static routes,
including one default route, in IP networks
