Seamless Integration with the IQ2000TM
Family of NPUs
The VSC2800 OctalMAC is a single chip
high-speed packet concentrator designed
to communicate via the FOCUS16 Interface
with Vitesse's IQ2000TM Architecture. The
OctalMAC combines high performance
packet transfer features, comprehensive packet-handling
capabilities, and automated statistics gathering for network
management support. The OctalMAC provides a cost effective
solution with excellent performance when used in conjunction
with Vitesse's IQ2000 family of network processors.
The integrated features of the OctalMAC offload the functions
of the Network Processor while simplifying the design and
lowering overall design costs. Vitesse's OctalMAC allows the
network processor to concentrate on providing next generation
services such as DiffServ and IPSec while delivering wire-rate
performance. The OctalMAC also reduces host processing
requirements by providing automated gathering of RMON and
SNMP network management statistics.
FOCUS16
The FOCUS Interface is a high performance, point-to-point
interface designed to efficiently transfer packet data between
Vitesse's IQ2000 family of network processors and peripheral
I/O interface devices or interconnect fabrics. In addition to
data transfer, the FOCUS Interface supports in band access to
statistics as well as command and status information.
G E N E R A L D E S C R I P T I O N :
VSC2800 OctalMAC Fast Ethernet Controller
Functionality
The device incorporates eight internal 10/100 Ethernet Media
Access Controllers (MACs), a single FOCUS16 Interface, and
a MII management controller. Each MAC is dual speed and
capable of half-duplex and full-duplex operation. Flow control
is provided in the half-duplex mode with backpressure. In full-
duplex mode, 802.3x frame-based flow control is supported.
Each MAC is 802.3 compliant and supports maximum frame
sizes up to 1536 bytes. The device also supports jumbo packets
up to 64Kbytes.
The eight Ethernet MACs interface directly to commercially
available PHY devices using either MII or RMII. The OctalMAC
can be configured on a per port basis to support a mixture of
MII and RMII PHY devices.
The OctalMAC includes automated statistics gathering on a per
port basis for layer management, SNMP, and RMON support.
The OctalMAC automatically counts the packet type, length,
errors, and other packet characteristics for both transmit and
receive. A total of 48 statistical counters per port are internally
maintained for use by system software in support of the various
Management Information Bases (MIBs) required by network
systems.
