VSC7372
HawX-G16™ – 16-Port 10/100/1000 Managed L2 Ethernet Switch
GENERAL DESCRIPTION:
The VSC7372 is a highly integrated, single
chip Ethernet switch with 16 nonblocking
10/100/1000 ports. As part of Vitesse's
HawX family of switches, the HawX-G16
enables intelligent local area network
(LAN) switching solutions focused on
quality of service (QoS), network security, and management to
maximize network performance, utilization, and efficiency.
With its sophisticated management feature set, the HawX
family can be used for a variety of metropolitan area network
solutions and control plane applications, in addition to
desktop and workgroup switches.
Managed LAN switches using the HawX-G16 can be used to
easily upgrade enterprise networks, providing GbE to the desktop
utilizing the existing cable infrastructure. Overall, network
performance can be increased with minimal IT spending.
HawX-G16 supports 16 ports of triple-speed 10/100/1000Mbps
SGMII/SerDes interfaces, wire-speed performance, and on-
chip memory. Features include jumbo frame support, link
aggregation, flow control, spanning tree, and port-based
access control. All the HawX switches provide unparalleled
QoS features necessary for building cost-effective layer 2
managed switch solutions. Key QoS benefits include
programmable multi-layer classification with 8 priorities,
minimum guaranteed bandwidth allocation, per queue
shaping and policing with Committed Info Rate (CIR) and Peak
Info Rate (PIR) policies, and Differentiated Services Code
Point (DSCP) remarking.
The VSC7372 includes an extensive suite of software
solutions, development tools, and technical support.
Software API and SDK solutions are available and nearly
100% compatible to all other Vitesse Ethernet switches.
Vitesse reference designs, coupled with the API and SDK
solutions, enable vendors developing their own hardware and
software systems to begin design immediately. For customers
wanting simpler development, turnkey software solutions are
available through 3rd party vendors.
