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 datapacket 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 Catalyst3750 Series supportsa comprehensive set of security features for connectivityand 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

EachCisco Catalyst 3750 Series stack is managed as a singleobjectandhasa 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.

IPv6 Capable—Getting Ready for the Future

The Catalyst 3750 supports IPv6 routing in hardware for maximum performance. As network devices grow and

the need for larger addressing and higher security become necessary, the Catalyst 3750 will be ready to meet the

requirement.

Standard Power over Ethernet Support—Graceful Addition of IP Communications

The 3750 Power over Ethernet (PoE) models support Cisco IP phones and Cisco Aironet wireless LAN access points,

as well as any IEEE 802.3af compliant end device. The Catalyst 3750 24-port version can support 24 simultaneous

full powered PoE ports at 15.4 Watts for maximum powered device support. The 48-port version can deliver the

necessary power to support 24 ports at 15.4 W, 48 ports at 7.7 W, or any combination in-between.
