Overview
For midsized organisations and enterprise branch offices, the Cisco WS-C3750G-48TS-S Catalyst 48-Port Layer 2 Stackable Gigabit Switch eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network services configurations. In addition, this stackable Cisco WS-C3750G-48TS-S switch is optimised for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.

Key Features

Forty-Eight (48) 10/100/1000 Gigabit Ethernet RJ45 ports with Auto-MDIX negotiation
Four (4) Gigabit SFP ports for high speed network expansion or use with a Cisco SFP module
Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to optimise bandwidth.
Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing.
Cisco StackWise stacking creates a 32-Gbps switch interconnection and does not require user ports. Up to 9 units can be stacked together for a maximum of 468 ports.
Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across all switches.
DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses.
Cross-Etack QoS allows QoS to be configured across the entire stack.
Cisco EnergyWise lowers operational cost optimisation by measuring, reporting, and reducing energy consumption across the entire infrastructure
IP Base software includes advanced quality of service (QoS), rate limiting, access control lists (ACLs), Open Shortest Path First (OSPF) for routed access, and IPv6 functionality
Cisco Network Assistant Software provides an easy-to-use, Web-based management interface through a standard Web browser.

Cisco StackWise Technology offers Stackable Resiliency
Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches into a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.

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 loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.

Cisco EnergyWise Technology
Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3750 switches, promoting companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the power consumption of network infrastructure and network-attached devices and manage power consumption with specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered device.

EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure and control energy between network devices and endpoints. The network discovers Cisco EnergyWise manageable devices, monitors their power consumption, and takes action based on business rules to reduce power consumption. EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices, making it simpler than traditional network management capabilities. Cisco EnergyWise's management interfaces allow facilities and network management applications to communicate with endpoints and each other using the network as a unifying fabric. The management interface uses standard SNMP or SSL to integrate Cisco and third-party management systems.

Cisco EnergyWise extends the network as a platform for the power control plane for gathering, managing, and reducing power consumption of all devices, resulting in companywide optimised power delivery and reduced energy costs.

Mix-and-Match Switch Types: Pay as You Expand Your Network
Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E switches. Customers who need a mixture of 10/100 and 10/100/1000 ports and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.

Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Cisco WS-C3750G-48TS-S Catalyst switch increases availability for stackable switches. Each switch can operate as both a master controller and a forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.

Smart Multicast: A New Level of Efficiency for Converged Networks
With Cisco StackWise technology, a Cisco Cisco WS-C3750G-48TS-S switch offers greater efficiency for multicast applications such as video. Each data packet is put onto the backplane 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-E and 3750 Series offer Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic, all at wire speed.

Network Security: Granular Control for the Access Environment
The Cisco WS-C3750G-48TS-S 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. This set of comprehensive features not only helps prevent external attacks, but also defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment.

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, VLAN creation and modification, network security, and QoS controls.

Jumbo Frames: Support for High-Demand Applications
The Cisco Catalyst 3750 Series supports jumbo frames on the 10/100/1000 configurations for advanced data and video applications requiring very large frames. All Cisco Catalyst 3750-E Series switch models also support jumbo frames.

IPv6 Support
The Cisco WS-C3750G-48TS-S supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco Cisco WS-C3750G-48TS-S Catalyst switch will be ready to meet the requirement.
