WS-C3560E-12D-E

Key Features of Cisco WS-C3560E-12D-E:

1. 12 Gigabit Ethernet Ports:

   • The WS-C3560E-12D-E provides 12 Gigabit Ethernet ports (10/100/1000 Mbps) that can support high-speed data transfer for devices such as computers, servers, and networked printers.
   • These Gigabit ports make it suitable for environments requiring high bandwidth and performance.

2. Advanced Layer 3 Routing:

   • The WS-C3560E-12D-E is a Layer 3 switch, meaning it can perform routing between different VLANs (Virtual LANs) and support advanced routing protocols such as OSPF (Open Shortest Path First), EIGRP (Enhanced Interior Gateway Routing Protocol), and RIP (Routing Information Protocol).
   • This ability to route traffic at Layer 3, combined with VLAN support, makes it ideal for larger networks or networks that require VLAN segmentation and routing between multiple subnets.

3. Power over Ethernet (PoE) Support:

   • While the WS-C3560E-12D-E itself does not offer Power over Ethernet (PoE) capabilities, it does support an optional PoE module, making it possible to deliver power to PoE-enabled devices like IP phones, wireless access points, and cameras.
   • The modular nature of the 3560-E Series allows you to add PoE capabilities as needed.

4. Redundant Power Supply (RPS) Capability:

   • The WS-C3560E-12D-E can be equipped with an optional Cisco Redundant Power Supply (RPS) for increased reliability and fault tolerance. In the event that the primary power supply fails, the RPS can provide backup power to ensure the switch remains operational.
   • This is critical in environments where uptime and availability are important.

5. Stackable for Scalability:

   • The WS-C3560E-12D-E supports Cisco StackWise Plus technology, which enables the switch to be stacked with other 3560-E switches. Stacking provides the ability to manage multiple switches as a single unit, simplifying configuration and maintenance.
   • Stacking also improves network resilience, as if one switch in the stack fails, the other switches can continue to operate without disruption.

6. Advanced QoS (Quality of Service):

   • The WS-C3560E-12D-E includes QoS features that allow for prioritization of critical traffic, such as voice, video, and real-time data. These features ensure that important applications have the required bandwidth and low latency.
   • QoS ensures that your network can handle multimedia traffic (e.g., VoIP, video conferencing) without compromising performance.

7. Comprehensive Security Features:

   • The WS-C3560E-12D-E offers robust security features, including:
     • 802.1X Port-Based Authentication: For controlling which devices can connect to the network based on user credentials.
     • Access Control Lists (ACLs): For filtering and controlling traffic based on IP addresses and other criteria.
     • Dynamic ARP Inspection (DAI): Prevents ARP spoofing attacks by ensuring the integrity of ARP messages.
     • DHCP Snooping: Protects against unauthorized DHCP servers by ensuring that only trusted servers are allowed to assign IP addresses.

8. Cisco IOS Software:

   • The WS-C3560E-12D-E runs Cisco IOS Software, which provides a powerful set of networking features including routing, security, monitoring, and management tools.
   • The Enterprise Services image on this switch includes advanced features like IP routing, multicast routing, virtual routing and forwarding (VRF), and more.

9. Stacking Bandwidth:

   • StackWise Plus technology allows for up to 64 Gbps of stacking bandwidth. This ensures that as the stack of switches grows, there is sufficient bandwidth to handle the traffic between them.

10. Fan and Cooling:

    • The WS-C3560E-12D-E is equipped with internal cooling fans to ensure efficient heat dissipation and maintain the reliability of the switch. The fans adjust their speed based on temperature conditions.

Use Cases for Cisco WS-C3560E-12D-E:

1. Enterprise Networks:

   • The WS-C3560E-12D-E is well-suited for enterprise networks, where it can be deployed in the access layer or distribution layer.
   • With Layer 3 routing, it can perform inter-VLAN routing, making it ideal for networks that need to route traffic between different VLANs and support advanced features like multicast and QoS.

2. Campus Networks:

   • This switch is also used in campus network environments where high-speed connectivity and efficient routing are required. It can easily connect multiple buildings or campus locations and deliver reliable routing for network communication across VLANs and subnets.

3. Branch Office Connectivity:

   • The WS-C3560E-12D-E can be used in branch offices that need secure and reliable networking. Its Layer 3 capabilities allow it to route traffic between VLANs at the branch level, reducing the need for additional routers.
   • With stacking support, multiple switches can be used for redundancy and scalability as the branch office grows.

4. IP Telephony:

   • The WS-C3560E-12D-E is suitable for IP telephony deployments, as it supports QoS, which prioritizes voice traffic to ensure high-quality VoIP (Voice over IP) calls.
   • Additionally, if an optional PoE module is installed, it can provide power to IP phones, wireless access points, and other PoE-enabled devices.

5. Data Centers and Server Farms:

   • The WS-C3560E-12D-E is a strong choice for use in data centers or server farms, where high throughput and redundancy are required. It offers gigabit Ethernet ports for fast connections to servers and other data center equipment.

6. Wireless Networks:

   • For wireless LAN (WLAN) environments, this switch is well-suited to provide PoE to wireless access points while managing the routing and segmentation of traffic across different VLANs in the network.
