 switches, the industry’s most 
advanced and versatile portfolio of modular and fixed-configuration 
LAN switches.
Individually, these switches offer the performance and features 
required for virtually any deployment, from small workgroups 
and wiring closets to corporate data centers and network cores. 
Working together, they are the building blocks of an integrated 
network that delivers intelligent services from the wiring closet to 
the core-protecting, optimizing, and growing your network as your 
business needs evolve.
The network is the platform for transforming the way people live, 
work, and play by enhancing application performance and creating 
new experiences. The proliferation of powerful desktop computers, 
bandwidth-intensive applications, and new devices, such as 
wireless access points, IP phones, and video surveillance has left 
networks—and network managers—looking for holistic and simple 
solutions to their business challenges.
Cisco, the worldwide leader in networking systems for organizations 
of every size, offers an architectural approach to networking that 
makes it easy for organizations to adapt and grow. As part of the 
foundation of the human network, Cisco Catalyst switches provide 
the application intelligence, unified network services, integrated 
security, non-stop communications, virtualization, and operational 
manageability needed for today’s most valuable converged 
network services, including networked applications, IP voice and 
video, wireless access, and other demanding applications.
