INTCOMEX - Premiere distributor of a wide range of computer products

Product description

For midsized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network-services configurations. In addition, the Cisco Catalyst 3750 Series is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.

Product features

Ease of use: "Plug-and-Play" configuration
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS software revision running on the stack to the switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
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-E switch. 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 Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.
Integrated Wireless LAN controller
The Cisco Catalyst 3750G Integrated Wireless LAN controller integrates Wireless LAN controller functions into the Cisco Catalyst 3750G series switch and delivers improved operating efficiency and WLAN security, mobility, and ease of use for business-critical Wireless LANs. The Cisco Catalyst 3750G Integrated Wireless LAN controller delivers centralized security policies, wireless intrusion prevention system (IPS) capabilities, RF management, QoS, and Layer 3 fast secure roaming for WLANs. As a core component of the Cisco Unified Wireless Network, the Cisco Catalyst 3750G Integrated Wireless LAN Controller provides the control, security, redundancy, and reliability that network managers need to scale and manage their wireless networks as easily as they scale and manage their traditional wired networks.
Availability: uninterrupted performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 series increases availability for stackable switches. The switch can operate as both a master controller and a forwarding processor. It 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-E series offers Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. 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 also defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment.
Single IP management: many switches, one address
Cisco Catalyst 3750 series 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.
IPv6 support
The Cisco Catalyst 3750 series supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco Catalyst 3750 series will be ready to meet the requirement.
