WS-C2960-48TT-L

Key Features:

1. 48 Gigabit Ethernet Ports:

   • The WS-C2960-48TT-L provides 48 Gigabit Ethernet ports (10/100/1000 Mbps) for connecting a large number of devices, such as computers, printers, VoIP phones, and access points.
   • These ports deliver high-speed connectivity suitable for enterprise environments with moderate traffic demands.

2. Layer 2 Switching:

   • This model primarily operates as a Layer 2 switch, handling Ethernet frames and facilitating the movement of data within a local area network (LAN) based on MAC addresses.
   • It supports basic Layer 2 features such as VLANs (Virtual LANs), Spanning Tree Protocol (STP), and Link Aggregation (EtherChannel) to optimize network traffic and avoid bottlenecks.

3. Layer 3 Lite (Limited Routing Capabilities):

   • The WS-C2960-48TT-L also has basic Layer 3 capabilities. These include static routing (manually configured routing between different VLANs). However, it does not support advanced dynamic routing protocols like OSPF or EIGRP.
   • It is considered a Layer 3 Lite switch, which is a good option for organizations that need some routing functionality but do not require advanced Layer 3 routing features.

4. Stacking Capability:

   • The WS-C2960-48TT-L supports Cisco StackWise technology, which allows for stacking multiple switches into a single logical unit. This increases network redundancy and scalability.
   • By stacking switches, you can simplify network management and create a more resilient network with higher bandwidth and fault tolerance.

5. Power over Ethernet (PoE) Option:

   • The WS-C2960-48TT-L does not have PoE support built in, but there is a similar model, the WS-C2960-48P-L, which offers PoE capabilities. If you’re planning to power devices like IP phones, wireless access points, or cameras directly from the switch, you would want to choose a model with PoE.

6. Advanced Security Features:

   • Cisco Catalyst switches, including the WS-C2960-48TT-L, come with advanced security features, such as:
     • Port security to limit the number of MAC addresses on a port.
     • Access Control Lists (ACLs) for traffic filtering.
     • 802.1X authentication for secure network access control, ensuring that only authorized devices can connect to the network.

7. QoS (Quality of Service):

   • The switch supports QoS (Quality of Service) features, which allow prioritization of traffic. This is useful in environments where specific types of traffic (e.g., voice or video) need to be prioritized to ensure quality.
   • Features like traffic shaping and traffic policing help manage bandwidth more efficiently, ensuring critical applications get the necessary resources.

8. Energy Efficient:

   • Cisco’s Catalyst 2960 Series is designed with energy efficiency in mind. The WS-C2960-48TT-L supports Energy Efficient Ethernet (EEE), which reduces the power consumption of the switch when network activity is low, contributing to overall power savings in your network.

9. Simple Network Management:

   • The WS-C2960-48TT-L can be easily managed using Cisco’s Device Manager (Web-based GUI), Command Line Interface (CLI), or Cisco Network Assistant for simplified setup and troubleshooting.
   • It also supports SNMP (Simple Network Management Protocol) for network monitoring and integration with third-party network management platforms.

10. Cisco IOS Software:

    • The switch runs Cisco IOS Software, which provides a stable, feature-rich operating system with various networking protocols and features.
    • Cisco IOS is highly recognized for its reliability, security, and flexibility in managing enterprise networks.

Specifications:

• Ports: 48 Gigabit Ethernet ports (10/100/1000 Mbps)
• Stacking: StackWise technology (up to 4 switches in a stack)
• Switching Capacity: 32 Gbps
• Forwarding Rate: 23.8 Mpps (Million packets per second)
• Power Consumption: Approximately 55W (without PoE support)
• Software Image: Runs on Cisco IOS LAN Base software (Layer 2 features and basic Layer 3 routing)
• Dimensions: 1.73 x 17.5 x 11.2 inches (44 x 445 x 284 mm)
• Weight: Approximately 4.4 kg (9.7 lbs)
• Redundancy: Supports hot-swappable fan modules and redundant power supplies for high availability (if using the appropriate model with PoE).

Use Cases:

1. Small to Medium Enterprise Networks:

   • The WS-C2960-48TT-L is well-suited for small-to-medium-sized businesses that need reliable connectivity but don’t require advanced Layer 3 routing. It’s ideal for edge switching and provides high-density Gigabit Ethernet connections for devices like desktops, servers, and access points.

2. Branch Office Networks:

   • This model can be used in branch office deployments where basic Layer 2 switching and some Layer 3 routing between VLANs are required. It can serve as an access switch to connect end-user devices while providing inter-VLAN routing on a limited scale.

3. Campus Networks:

   • The WS-C2960-48TT-L can be deployed as part of a campus network for high-density connectivity. Its stacking capabilities make it ideal for building a scalable, redundant network.

4. Cost-Effective Solution for Converged Networks:

   • While the WS-C2960-48TT-L does not support PoE, it is an ideal solution for environments where converged networks (data, voice, and video over Ethernet) are needed but PoE isn’t required. It provides reliable Layer 2 switching at a lower cost compared to higher-end models.

Differences from Other Models in the 2960 Series:

• No PoE: The WS-C2960-48TT-L lacks Power over Ethernet (PoE) support, which means it cannot power devices like IP phones or wireless access points directly. For PoE, you would need to look at models such as the WS-C2960-48P-L (PoE) or WS-C2960-48FP-L (Full PoE).
• Layer 3 Lite: While it offers limited Layer 3 capabilities (like static routing), it is not as feature-rich as other models in the 2960X or 2960XR series, which support more advanced dynamic routing protocols and additional Layer 3 features.
• Lower Switching Capacity: Compared to more advanced models in the Catalyst 2960X series, the WS-C2960-48TT-L offers a lower switching capacity and may be more suitable for smaller-scale environments.
