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, PoE, 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.
Integrated Wireless LAN Controller
The Cisco Catalyst 3750G Integrated Wireless LAN Controller integrates wireless LAN controller
functions into the Cisco Catalyst 3750G Series Switches and delivers improved operating
efficiency and WLAN security, mobility, and ease of use for business-critical wireless LANs. The
Cisco Catalyst 3750G Integrated Wireless LAN Controller delivers centralized security policies,
wireless intrusion prevention system (IPS) capabilities, award-winning RF management, QoS, and
Layer 3 fast secure roaming for WLANs. As a core component of the Cisco Unified Wireless
Network, the Cisco Catalyst 3750G Integrated Wireless LAN Controller provides the control,
security, redundancy, and reliability that network managers need to scale and manage their
wireless networks as easily as they scale and manage their traditional wired networks.
Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 Series 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, the Cisco Catalyst 3750 Series 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 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. 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.
