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 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.
IPv6 Support
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.
