Cisco Catalyst 2960 Series
Cisco Catalyst 2960 Series Intelligent Ethernet switches, a new line of fixed-configuration standalone devices, provide desktop Fast Ethernet and Gigabit Ethernet connectivity for entry-level enterprise, mid-market, and branch office networks, helping enable enhanced LAN services.
The Catalyst 2960 Series offers integrated security, including network admission control (NAC), as well as advanced quality of service (QoS) and resiliency, delivering intelligent services for the network edge.
The series also includes a number of hardware enhancements for network managers, including configurations featuring dual-purpose (alternatively wired) uplinks for Gigabit Ethernet, allowing the network manager to use either a copper or a fiber uplink. Also included is a 24-port Gigabit Ethernet family member, accelerating Gigabit to the Desktop (GTTD) across the network.
Table 1 provides brief descriptions of the switches in the Catalyst 2960 Series.
The Catalyst 2960 Series offers the following benefits:
• Intelligent features at the network edge, such as sophisticated access control lists (ACL) and enhanced security.
• Dual-purpose uplinks for Gigabit Ethernet uplink flexibility, allowing use of either a copper or a fiber uplink. Each dual-purpose uplink port has one 10/100/1000 Ethernet port and one SFP-based Gigabit Ethernet port, with one port active at a time.
• Network control and bandwidth optimization through advanced QoS, granular rate-limiting, ACLs, and multicast services.
• Network security through a wide range of authentication methods, data encryption technologies, and network admission control based on users, ports, and MAC addresses.
• Easy network configuration, upgrades, and troubleshooting as part of the mid-market or branch solution using the embedded Device Manager and Cisco Network Assistant.
• Auto-configuration for specialized applications using Cisco Smartports.
Cisco Catalyst 3750 Switches
The Cisco Catalyst 3750 Series switches are a premier line of enterprise-class, stackable, multilayer switches that provide high availability, security, and quality of service (QoS) to enhance the operation of the network. Its innovative unified stack management raises the bar in stack management, redundancy, and failover.
With a range of Fast Ethernet and Gigabit Ethernet configurations, the Cisco Catalyst 3750 Series can serve as both a powerful access layer switch for medium enterprise wiring closets and as a backbone switch for mid-sized networks. Customers can deploy network wide intelligent services, such as advanced QoS, rate-limiting, Cisco security access control lists (ACLs), multicast management, and high-performance IP routing—while maintaining the simplicity of traditional LAN switching. Embedded in the Cisco Catalyst 3750 Series is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Cisco Catalyst desktop switches using a standard Web browser.
Key Features & Benefits of Cisco 3750 Switches
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 new 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.
The Cisco 3750 Series stacks up to nine switches as a single logical unit for a total of 468 Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or nine 10 Gigabit Ethernet ports.
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 and Cisco Catalyst 3750-E series. 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.
Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 switch increases availability for stackable switches. Each switch can operate as both a master controller and a 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 3750 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 3750 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
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 3750 Series Switch 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 becomes critical, the Cisco 3750 switch 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 Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.
10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments
The Cisco Catalyst 3750 allows network managers to incrementally add IEEE 802.3ae-compliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating and enhancing Gigabit Ethernet networks. This provides investment protection to customers who want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and provide higher performance to applications and users.
The Cisco 3750 Series switch offers both a superior command-line interface (CLI) for detailed configuration and Cisco Network Assistant Software, a Web-based tool for quick configuration based on preset templates. In addition, CiscoWorks supports the Cisco Catalyst 3750 Series for network wide management.
