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 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 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 Switches 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, award-winning 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. 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 Catalyst 3750-E and 3750 Series offer 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

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.

3750-48PS, 3750-24PS specifications

Cisco Systems has long been a leader in the networking industry, providing robust solutions that cater to diverse organizational needs. Among its array of products, the Cisco Catalyst 3750 series stands out, particularly the models 3750-24PS and 3750-48PS. These switches are designed for the enterprise market, delivering high performance, advanced features, and exceptional flexibility.

The Cisco Catalyst 3750-24PS is a 24-port Ethernet switch that comes equipped with Power over Ethernet (PoE) capabilities, allowing it to supply power to connected devices such as IP phones and wireless access points. This model supports both Layer 2 and Layer 3 operations, providing a versatile solution suitable for various network topologies. The switch boasts a 2.5 Gbps stack bandwidth, enabling seamless integration into Cisco's StackWise technology. This feature allows multiple switches to be interconnected, functioning as a single unified system, which enhances network scalability and management.

On the other hand, the Cisco Catalyst 3750-48PS features 48 Ethernet ports with PoE support, making it an excellent choice for larger deployments. This model offers enhanced connectivity options and greater power capabilities, catering to more substantial device populations within enterprises. Like its 24-port counterpart, it supports VLANs, which facilitate traffic segregation for optimal network performance.

Both models support advanced Layer 3 routing protocols, including RIP, OSPF, and EIGRP, allowing for efficient routing within the network. The Quality of Service (QoS) capabilities ensure optimal delivery of time-sensitive applications, such as voice and video, providing a seamless user experience.

Another remarkable feature of the Cisco Catalyst 3750 series is the incorporation of Cisco's Smart Install technology, which simplifies switch deployment and management. This technology automates device configuration and software upgrades, reducing the operational burden on network administrators.

Security is a priority in today’s networking environment, and the 3750 series includes numerous security features. This encompasses features like dynamic ARP inspection, DHCP snooping, and port security, which work in concert to safeguard data integrity and access controls.

In summary, the Cisco Catalyst 3750-24PS and 3750-48PS are exceptional switches that deliver a blend of performance, flexibility, and security. Their advanced features make them suitable for both small and large enterprises, effectively meeting the demands of modern networking environments while ensuring scalability and manageability.
