Data Sheet

Return on Investment Through Lower Operations Costs

The automatic Cisco IOS Software version checking and loading of the global configuration

parameters provide the first level of operational time saving. The second level is added during the

event of an outage. When you remove a troubled switch from an existing stack of switches and

replace it with another switch, the master switch will recognize this as a maintenance outage and

automatically reload the port-level configuration that was on the previous switch without user

intervention. This allows IT managers to have local personnel in remote locations perform

maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving

thousands of dollars in operational 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, 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
