Catalyst Series Switches Consulting Services From CCIE and CCNP Certified Professionals
The Cisco Catalyst family of modular and fixed-configuration switches provide intelligence and performance at the core, distribution, and access levels of networks for organizations that range in size from small businesses and branch offices to global enterprises and service providers. The need for intelligent switching is fueled by four important trends:
Growth in desktop processing ability
Introduction of bandwidth-consuming applications
Expansion of confidential data on the network
Greater variety of appliances like IP phones and cameras and wireless LAN bridges
The latest line-of-business applications demand higher bandwidth resulting in a need to differentiate and manage network traffic. Applications like digital voice need a higher priority to network bandwidth than less performance-sensitive applications like File Transfer Protocol or, for messaging, Simple Mail Transfer Protocol. It is not any longer acceptable, for example, for a large file transfer destined to one port on a switch to increase the latency, and lower the intelligibility, in voice data destined to a different port on the same switch. This situation is eliminated by ensuring that voice traffic is appropriately classified and expedited throughout the network.
Cisco Catalyst switches implement industry-leading Quality of Service (QoS) to help ensure that network traffic is differentiated and assigned priorities, and that bottlenecks are eliminated. Set up of Quality of Service (QoS) is greatly streamlined through automatic Quality of Service, a process that senses Cisco IP phones and sets up the switch for the right categorization and egress buffering. This optimizes traffic hierarchies and network accessibility without requiring your IT group to devise a complicated set up plan.
Through Catalyst switches for small and midsize businesses, Cisco allows businesses to realize all the benefits of incorporating intelligent services into their network architecture. Catalyst switches make it possible to deploy capabilities that make the network infrastructure responsive to handle real time requirements, scalable to facilitate future growth, secure so as to guard sensitive data, and capable of differentiating and managing processes to enhance network operations.

Interoperation with Cisco wireless access points allows organizations to build a local wireless environment rapidly and easily. The Cisco Catalyst Express 500 and 520 family offers advanced security against malicious attacks thanks to the Cisco Self-Defending Network technology and Clean Access agents.
Catalyst 2900 Line
Cisco Catalyst 2900 fixed-configuration, managed 10/100 switches offer basic workgroup networking for small to medium-sized organizations. These wire-speed desktop switches offer IOS Software functions for basic mixed-media traffic services at the network edge.
The Catalyst 2940 family of managed switches are small, entry-level devices with 8 Ethernet connections and a single built-in Fast or Gigabit Ethernet uplink. They can be installed outside the wiring cabinet in cramped locations such as on or under a worker's desk or in a conference room. Catalyst 2940 switches work with Cisco's IOS control software for comprehensive security and simple administration.
Cisco 2960 Series switches are compact and silent for use in work spaces next to employees instead of in wiring cabinets. Cisco Catalyst 2960 Series switches come in 24-port and 48-port Gbit Ethernet models and are offered in two types. Cisco Catalyst 2960 switches configured with Cisco LAN Lite IOS Software provide entry-level protection, QoS, and high availability at an affordable cost. Cisco 2960 switches configured with LAN Base software support Fast Ethernet and Gbit connectivity and offer optional PoE. These versions also feature integrated security, including Network Admission Control, and advanced QoS.
Catalyst 3560 Series Switches
The Catalyst 3560 family is a line of non-modular switches that features IEEE 802.3af and Cisco Power over Ethernet (PoE) functionality in 10/100 Ethernet and 10/100/1000 Ethernet configurations. The Cisco Catalyst 3560 is a proven Layer 2 switch for midsize business network connectivity or satellite-office environments, offering both Gigabit and PoE options for maximum efficiency and fast ROI while streamlining the deployment of the latest applications such a Voice over IP, WiFi, video surveillance, and remote video kiosks. Customers can deploy network-wide smart features such as high-end QoS, rate limiting, ACLs, multicast management, and broadband IP routing while maintaining the ease of traditional network switching.
The Catalyst 3560 Series switch is provided with a robust array of capabilities that allow for network scalability and enhanced availability via IP routing as well as a complete suite of Spanning Tree Protocol (STP) improvements designed to increase throughput in an access Layer network. Improvements to the standard Spanning Tree Protocol (STP), such as Per-VLAN Spanning Tree Plus, and Uplink Fast, plus advances like as Flex Links Layer 2 interfaces, optimize network efficiency. Per-VLAN Spanning Tree Plus allows for Data Link Layer load balancing on redundant connections to take advantage of the extra capacity inherent in a redundant architecture.
Advanced routing protocols such as OPSF, EIGRP, BGP, and Policy Based Routing increase network scale; PIM maximize network resources; and Virtual Route Forwarding Lite secures traffic.
Cisco Catalyst 3750 Series Switches
For midsized organizations and enterprise local sites, Cisco's Catalyst 3750 Series switch facilitates deployment of converged technologies and adapts to changing competitive needs by providing configuration flexibility, support for converged network patterns, and automatic configuration of smart system services. In addition, Cisco's Catalyst 3750 Series is optimized for high-volume Gigabit environments and includes a wide range of switches that comply with connectivity, aggregation, or small-network backbone-interface demands.
Cisco's Catalyst 3750 Series is available with either the IP Base or the Services image. The IP Base image capabilities include advanced QoS, rate-limiting, access control lists (ACLs) access control lists, and basic static and RIP routing capability. The IP Services image provides a richer selection of enterprise network functions, such as sophisticated hardware-based IP unicast and multicast routing.
StackWise technology is a mechanism optimized for Gigabit Ethernet. StackWise is intended to react to additions, deletions, and relocations while providing constant performance. Cisco StackWise unites as many as 9 individual switches into a single logical unit, utilizing special stack-interconnect cables and utilities. The individual switches can be any combination of Cisco's Catalyst 3750 Series and the Catalyst 3750-E Series. The stack behaves as an individual switching device that is directed by a master switch, chosen from among the member switches. The master switch automatically builds and updates all the switching and optional routing tables. A deployed stack can accept new devices or remove existing switches with no service interruption.
