FEATURES:
f 16 Gigabit Ethernet ports with non-blocking wire-speed performance
f 8 integrated tri-speed (10/100/1000 Mbps) copper transceivers (IEEE
802.3ab™ compliant) and 8 tri-speed SGMII ports
f 500 kb on-chip frame buffer
f Per-port data rate policer and shaper with a granularity of 64 kbps for
both ingress and egress direction
f Selection between on-chip V-Core CPU or off-chip 8-bit CPU for fully
managed applications
f DSCP remarking for both IPv4 and IPv6 frames
f Jumbo frame support on all ports
f Programmable classifier for QoS, including IEEE Std 802.1p™ and
DSCP for IPv4 and IPv6, with 4 classes of service
f 8 k MAC addresses and 4 k VLANs (IEEE Std 802.1Q™)
f Flexible link aggregation compliant to IEEE Std 802.3ad™
f Full-duplex flow control (IEEE Std 802.3x™) and half-duplex back
pressure, symmetric and asymmetric
f Multicast and broadcast storm control as well as flooding control
f Vitesse VeriPHY™ cable diagnostics
f Multiple protocol support: IEEE Std 802.1D™, IEEE Std 802.1w™,
IEEE Std 802.1s™ and IEEE Std 802.1X™
BENEFITS:
f Ensures maximum data throughput on even highly loaded networks
f Lowers the overall systems cost by reducing the need for 8 external PHYs
f Eliminates the need for external buffer memory while maintaining high
peak load performance
f Enables pre-arranged bandwidth control and billing
f Enables advanced switch management using run-time protocols, in
addition to low cost unmanaged and Web-managed operation
f Enables LAN edge products to generate standard priority which can be
used in the core network
f Provides the support of frame sizes up to 12.2 k sized jumbo frames
f Optimizes network performance to support any digital stream, from internet
browsing to VoIP and video
f Stores a large amount of stations at wire speed in the on-chip MAC table,
ensuring optimal network performance
f Provides high bandwidth uplinking abilities
f Ensures loss-less data transmission while supporting existing legacy
Ethernet equipment
f Eliminates unwanted flooding of ports and thereby increases overall
network performance
f Enables sophisticated real time cable diagnostics
f Supports complex network topologies with fast failure recovery and access
control
APPLICATIONS:
f 16-port unmanaged Gigabit Ethernet SMB/SME/SOHO switch
f 16-port Web-managed smart Gigabit Ethernet SMB/SME/SOHO switch
