The Cisco® Catalyst® 3560 Series switches ( WS-C3560G-48TS-E  ) is a line of fixed configuration, enterprise-class, IEEE 802.3af and Cisco prestandard Power over Ethernet (PoE) switches in Fast Ethernet configurations that provide availability, security, and quality of service (QoS) to enhance network operations. The Catalyst 3560 is an ideal access layer switch for small enterprise wiring closets or branch office environments . The switch uses their LAN infrastructure for the deployment of new products and applications . It includes IP telephones, wireless access points, video surveillance, building management systems, and remote video kiosks. In the other hand, Customers can deploy network-wide intelligent services, such as advanced QoS, rate limiting, access control lists, multicast management, and high-performance IP routing-while maintaining the simplicity of traditional LAN switching. Embedded in the Catalyst 3560 is the Cisco Cluster Management Suite (CMS) Software. This methodology allows users to simultaneously configure and troubleshoot multiple Cisco Catalyst desktop switches using a standard Web browser
