FairoaksTM 24x1G + 2x10G Layer 2 Ethernet Switch-on-a-Chip
VSC7306
FairoaksTM is a highly integrated, single-chip
Ethernet switch with 24x1G and 2x10G non-
blocking ports. As part of Vitesse's LondonTM
Family of Switches, Fairoaks delivers high
performance with easy migration paths, and
comprehensive System Solutions that enable ultra-short time-
to-market and market leading system cost.
A Vitesse Switch Family Member
Fairoaks is a part of the Vitesse London Family of Switches.
With its 24 tri-speed ports and 2x10G ports, it is specifically
targeted at desktop/workgroup switch applications and
stackable switch applications. Fairoaks is well suited for
designing 48-port gigabit swith systems by utilizing two chips.
Being a member of the switch family provides a number of
unique advantages when designing with the chip, including
very high software compatibility between members. Thus,
software written for Fairoaks can easily be adapted and used
with other switch configurations in the family, and vice-versa.
Additionally, building a product family is easy when designing
with Vitesse switches. Migrating designs to other port counts or
future technology is achievable with minimum effort and time.
The Vitesse London Switch Family
Fairoaks, as part of the Vitesse London Family Of Switches,
shares the unique traits of the family.
The highly integrated switches require no external memory at
all, and the use of Reduced Mode interfaces (RGMII and
RTBI) simplifies PCB layout to reduce time and cost. Further
trimming down system cost is the persistently low power
dissipation of the family.
The switches provide for high performance designs with their
non-blocking, wire-speed performance, which includes wire-
speed MAC address learning.
G E N E R A L D E S C R I P T I O N :
Designing both unmanaged and managed solutions is
straightforward. The chips offer both serial and parallel CPU
interfaces, and support a host of management protocols such as
GxRP, SNMP, IGMP Snooping, and three flavors of Spanning Tree:
Standard STP, Multiple STP, and Rapid STP.
Gaining control with networks operated by the Vitesse switches is
simple; advanced Layer 2-4 classification, plus shaping and policing
functionality, along with port authentication support, provide flexible
QoS operation. This is backed up by link aggregation and VLAN
support, enabling advanced techniques such as "802.1Q-in-802.1Q"
to be deployed. Additionally, OAM is supported for designing switch
products for Ethernet in the First Mile (EFM).
Designing with Vitesse London Family of Switches means designing
with the whole Vitesse Solution:
The outstanding Vitesse web managed switch software system that
runs on a low cost CPU, is provided. This is in addition to the smart
managed software system, which is also included. Furthermore,
LVL7's FASTPATH stack is integrated for compatibility with Fairoaks
providing full management capability, and is available as well. For
homegrown software development our full platform and OS
independent switch API is supplied.
Accompanying the software systems are the Vitesse Switch
Reference Systems ("Jetway" for Fairoaks). These are production-
ready hardware designs that also serve as evaluation platforms for
our switches.
The Vitesse Solution is supplied with a comprehensive collateral
package, which includes software source code, full documentation,
and an in-depth qualification report for easy pre-evaluation.
