Scalability—Fast Ethernet to Gigabit Ethernet
The Cisco Catalyst 3750 Series stacks up to 9 switches as a single logical unit for a total of 468 Ethernet or Power
over Ethernet 10/100 ports or 252 Ethernet 10/100/1000 ports, or 9 10Gigabit Ethernet ports. Individual 10/100
and 10/100/1000 and 10Gigabit Ethernet units may be joined in any combination to evolve with network needs.
Mix-and-Match Switch Types—Pay as You Expand Your Network
Stacks can be created with any combination of Cisco Catalyst 3750 switches. Customers who need a mixture of
10/100, 10/100/1000 ports, Power over Ethernet, and wiring closet aggregation capability can incrementally develop
the access environment, paying only for what they need. When uplink capacity needs to be increased customers
can easily upgrade their bandwidth by adding a 10Gigabit Ethernet version to the stack and upgrade their one
Gigabit Ethernet links with 10Gigabit Ethernet on the existing fiber.
Availability—Non-Stop Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 Series increases availability for stackable switches. Each switch can operate both as master
controller and forwarding processor. Each switch in the stack can serve as a master, creating an 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 on to 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 Series offers Gigabit Ethernet speed with intelligent services that keep everything flowing
smoothly—even at ten times normal network speed. Industry-leading mechanisms for marking, classification, and
scheduling deliver best-in-class performance for data, voice, and video traffic—all at wire speed.
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.
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, virtual LAN creation and modification, security, and QoS controls.
Jumbo Frames—Support for High-Demand Applications
The Cisco Catalyst 3750 Series supports jumbo frames on the 10/100/1000 configurations for advanced data and
video applications requiring very large frames.
