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 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 1

Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.

Availability—Uninterrupted 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 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 Series offers Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly—even at 10 times

the 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.

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 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.

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.

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

addressing and higher security become critical, the Catalyst 3750 Series will be ready to meet the requirement.

Standard PoE Support—Graceful Addition of IP Communications

The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet

wireless LAN (WLAN) access points, as well as

any IEEE 802.3af-compliant end device. The Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at

1 2 3 4 ... 22
