Introduction

• The Cisco Catalyst® WS-C3750G-12S-E switch is an innovative product that improves LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. This product represents the next generation in desktop switches, and features Cisco StackWise technology, a 32Gbps stack interconnect that allows customers to build a unified, highly resilient switching system—one switch at a time.
  
• Ease of Use—"Plug-and-Play" Configuration: A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
  
• Scalability—Fast Ethernet to Gigabit Ethernet: The Cisco Catalyst WS-C3750G-12S-E stacks up to 9 switches as a single logical unit for a total of 468 Ethernet 10/100 ports or 252 Ethernet 10/100/1000 ports. Individual 10/100 and 10/100/1000 units may be joined in any combination to evolve with network needs.
  
• Mix-and-Match Switch Types—Pay as You Expand Your Network: Stacks can be created with any combination of Cisco Catalyst 3750 switches. Customers who need a mixture of 10/100 and 10/100/1000 ports can incrementally develop the access environment, paying only for what they need.
  
• Smart Multicast—A New Level of Efficiency for Converged Networks: With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for multicast applications such as video. Each data packet is put on to the stack interconnect only once, which provides more effective support for more data streams.
  
• Superior Quality of Service—Across the Stack and at Wire Speed: The Cisco Catalyst 3750 Series offers Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly—even at ten times normal network speed. Industry-leading mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic—all at wire speed.
  
• Security—Granular Control for the Access Environment: The Cisco Catalyst 3750 Series supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions.
  
• Single IP Management—Many Switches, One Address: Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address. Single IP management is supported for activities such as fault detection, virtual LAN creation and modification, security, and QoS controls.
