VSC7310-01
24-Port 10/100/1000 and 2-Port 10 Gbps Wire-Speed Stackable Layer-2/Layer-3 Ethernet Switch
GENERAL DESCRIPTION:
Gatwick-IeTM is a highly integrated, single-chip Ethernet switch/router with 24 x 1 Gbps and 2 x 10 Gbps non-blocking ports. Gatwick-Ie delivers high performance with easy migration paths and comprehensive system solutions that enable ultra-short time-to-market and market leading system cost.

Designing both unmanaged and managed solutions is straightforward. The devices offer both serial and parallel CPU interfaces, as well as supporting a host of management protocols such as GxRP, SNMP, IGMP Snooping, RIP v1 and v2, OSPF, 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 through Layer 4 classification, plus shaping/scheduling 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 a member of the Vitesse switch family means designing with the whole Vitesse solution: The outstanding Vitesse web-managed switch software system, which runs on a low-cost CPU, is provided. This is in addition to the smart-managed software system, which is also included. For software development, our full platform and OS-independent switch API is supplied. Accompanying the software systems are the Vitesse Switch Reference Systems. 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.
A Vitesse Switch Family Member With its 24 tri-speed ports and 2 x 10 Gbps ports, Gatwick-Ie is specifically targeted at desktop or workgroup switch applications. Gatwick-Ie is well suited for designing 48-port Gigabit Ethernet switch systems by using two devices. Being a member of the switch family provides a number of unique advantages when designing with the device, including very high software compatibility between the family members. As a result, software written for Gatwick-Ie 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 can be managed with a minimum of effort and time. The highly integrated switches require no external memory at all, and the use of Reduced Mode interfaces (RGMII) 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 and the wire-speed routing performance of Gatwick-Ie. The introduction of VStaXTM, Vitesse proprietary stacking architecture, enables collaboration and scalability.
