F E A T U R E S :
B E N E F I T S :
f 5+1 Gigabit Ethernet ports with nonblocking wire-speed performance
f Ensures maximum data throughput in highly loaded networks
f 5 tri-speed (10/100/1000 Mbps) copper transceivers (IEEE 802.3ab
f Reduces the need for any PHY components thereby significantly
compliant) and 1 tri-speed (RGMII/GMII) interface
reducing overall systems cost
f 136 kilobytes on-chip frame buffer
f Eliminates the need for external buffer memory while maintaining high
peak load performance
f SNMP and Web-based management with either V-Core CPU (on-chip
8051 CPU with royalty-free, Web-managed software stack) or off-chip
8-bit CPU
f Enables advanced switch management, using run-time protocols, and
low cost unmanaged/Web-managed operation
f DSCP remarking for both IPv4 and IPv6 frames
f Enables LAN edge products to generate standard priority that can be
used in the core network
f Enhanced support for IPv4 and IPv6 multicast, including IGMP
f Enables applications such as digital video distribution with efficient
snooping and MLD snooping
monitoring of IPv4 and IPv6 frames and multicast groups
f Jumbo frame support at all speeds (10/100/1000 Mbps)
f Connects effortlessly to networks, hosts, and controllers that use up to
9.6-kilobyte frames
f Programmable multilayer classifier with 4 QoS classes
f Optimizes network performance to support any digital stream, from
internet browsing to VoIP and video
f 8 k MAC addresses and 4 k VLANs (IEEE 802.1Q), as well as 8 k IP
f Stores a large amount of stations at wire-speed in the on-chip MAC
multicast group support
Table, ensuring optimal network performance and scalability
f Flexible link aggregation support based on Layer-2 through Layer-4
f Provides high bandwidth uplinking abilities
information (IEEE 802.3ad)
f Full-duplex flow control (IEEE 802.3X) and half-duplex backpressure,
f Ensures lossless data transmission while supporting existing legacy
symmetric and asymmetric
Ethernet equipment
f Multicast and broadcast storm control, as well as flooding control
f Eliminates unwanted flooding of ports, and thereby increases overall
network performance
f Multiple protocol support: IEEE 802.1D, IEEE 802.1w, IEEE 802.1s,
f Supports complex network topologies with fast failure recovery and
and IEEE 802.1X
access control
f Wire-speed automatic learning and aging
f Reduces CPU overhead and enables the CPU to allocate additional
cycles for protocol processing
f Vitesse VeriPHY™ cable diagnostics and SimpliPHY™ magnetics
f Enables real-time cable diagnostics and low cost magnetics
