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.
