Cisco Expert Network Consulting Catalyst Switches Support From CCIE and CCNP Qualified Experts
Cisco's latest line of smart switches are aimed at providing intelligence at the network edge, where one network communicates with another. The need for intelligence at the edge of the network is fueled largely by four key trends:
Increase in PC processing power
Introduction of bandwidth-intensive programs
Presence of confidential information on the network
Greater assortment of devices, such as Voice over IP phones and wireless LAN access points
The most recent line-of-business applications demand higher bandwidth and create the necessity to differentiate and manage traffic flow. Applications like enterprise resource planning and VoIP need more network bandwidth than less time-critical processes such as FTP or, for e-mail, SMTP. It is no longer justifiable, for example, for a big file download destined to a single port on a switch to extend the latency, and lower the intelligibility, in voice traffic destined to a different port on the same switch. This situation is eliminated by ensuring that voice processes are properly classified and expedited across the network.
Cisco switches deliver industry-leading QoS to make sure that network traffic is differentiated and prioritized, and that congestion is eliminated. Set up of Quality of Service (QoS) is greatly streamlined via automatic QoS (auto-QoS), a process that senses Cisco IP phones and sets up the switch for the appropriate classification and exit buffering. This optimizes process hierarchies and system availability without forcing your network management group to devise a complex set up plan.
Through Cisco Catalyst switches for small and midsize companies, Cisco allows organizations to get the full advantages of incorporating intelligent services into their infratstructure. Cisco's switches allow you to install capabilities that make the network infrastructure highly available to handle time-critical requirements, scalable to support growth, safe so as to guard sensitive data, and capable of differentiating and managing traffic flows to enhance network operations.

Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. Cisco StackWise is designed to respond to installs, deletions, and redeployments while maintaining constant operation. StackWise technology unites as many as nine individual switches into one logical unit, utilizing custom stack-interface cables and software. Any of the switches can be any combination of the Catalyst 3750 Series and the Catalyst 3750-E switches. The stack behaves as an individual switching device that is directed by a control switch, selected from one of the stack of switches. The master switch intelligently builds and updates all the switching and optional routing tables. A deployed stack can accept new devices or delete old switches without service interruption.
