Product Data Sheet / Brochure

Port isolation : secures and adds privacy, and prevents malicious attackers from obtaining user information
STP BPDU port protection : blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged
BPDU attacks
STP Root Guard : protects the root bridge from malicious attacks or configuration mistakes
DHCP protection : blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
Dynamic ARP protection : blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
IP Source Guard : helps prevent IP spoofing attacks
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 that provides easy mapping of
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
IP multicast snooping (data-driven IGMP): automatically prevents flooding of IP multicast traffic
Multicast VLAN : allows multiple VLANs to receive the same IPv4 or IPv6 multicast traffic, lessening network bandwidth demand
by reducing or eliminating multiple streams to each VLAN
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
Additional information
Green IT and power : use the latest advances in silicon development, shut off unused ports, and use variable-speed fans to
improve power efficiency
Green initiative support : provides support for RoHS and WEEE regulations
