HP A3100-24-PoE EI JD313A Datenbogen

4

• Dynamic ARP protection: blocks ARP

broadcasts from unauthorized hosts, preventing
eavesdropping or theft of network data

• IP Source Guard: filters packets on a per-port

basis, which prevents illegal packets from being
forwarded

• RADIUS/HWTACACS: eases switch management

security administration by using a password
authentication server

Convergence

• IEEE 802.1AB Link Layer Discovery Protocol

(LLDP): is an automated device discovery protocol
for easy mapping by network management
applications

• LLDP-MED: is a standard extension that

automatically configures network devices, including
LLDP-capable IP phones

• LLDP-CDP compatibility: receives and

recognizes CDP packets from Cisco's IP phones for
seamless interoperation

• IEEE 802.3af Power over Ethernet: provides

up to 15.4 W per port to PoE-powered devices such
as IP phones, wireless access points, and video
cameras

• PoE allocations: support multiple methods

(automatic, IEEE 802.3af class, LLDP-MED, or user
specified) to allocate PoE power for more efficient
energy savings

• Voice VLAN: automatically assigns VLAN and

priority for IP phones, simplifying network
configuration and maintenance

• Multicast VLAN: allows multiple VLANs to receive

the same IPv4 or IPv6 multicast traffic, reducing
network bandwidth demand by eliminating multiple
streams to each VLAN

• IGMP/MLD snooping: effectively controls and

manages the flooding of multicast packets in a Layer
2 network

Device support

• Cisco prestandard PoE support: detects and

provides power to Cisco's prestandard PoE devices
such as wireless LAN access points and IP phones

Flexibility

• Designed with no fan: enables quiet operation

for deployment in open spaces

Additional information

• Green initiative support: provides support for

RoHS and WEEE regulations

• Green IT and power: uses the latest advances in

silicon development and shuts off unused ports to
improve power efficiency
