Advanced Security Features

The WS-C3750X-12S-E Cisco Catalyst 3750X Series switch is a managed switch that offers advanced security features to help protect the network it is connected to. Some of these features include:

  • Access Control Lists (ACLs): This feature allows the administrator to define and implement security policies that control which devices and users are allowed to access the network, and what they are allowed to do.
  • Port Security: This feature allows the administrator to define which devices are allowed to connect to a specific switch port, and to set limits on the number of MAC addresses that can be learned on a port.
  • DHCP snooping: This feature helps to prevent DHCP spoofing by allowing the switch to validate DHCP messages and only allow DHCP messages from authorized DHCP servers to be passed through.
  • Dynamic ARP Inspection (DAI): This feature helps to prevent ARP spoofing by validating ARP packets and only allowing packets from valid hosts to be passed through.
  • Private VLAN: This feature allows the administrator to segment a network into multiple smaller, isolated networks, which can help to increase security and reduce the risk of unauthorized access.
  • IEEE 802.1x: This standard allows for the authentication of devices that connect to the network, ensuring that only authorized devices can access the network.
  • IP Source Guard: This feature helps to prevent IP spoofing by only allowing IP packets to be passed through if they have a source IP address that is valid for the connected host.
  • Cisco TrustSec: This feature allows the administrator to define and implement security policies that control access to network resources based on the identity of the user or device.
  • Advanced Encryption Standard (AES) encryption: This feature allows the administrator to encrypt sensitive data that is transmitted across the network, protecting it from eavesdropping and tampering.

All these features provide a comprehensive set of security tools that help to protect the network from unauthorized access and attacks, and increase the overall security of the network.

More Specifications

The WS-C3750X-12S-E is a managed switch from the Cisco Catalyst 3750X series, which is a line of enterprise-class switches that provide high availability, scalability, security, and energy efficiency. This particular model has 12 SFP ports, which support fiber optic cables and can be used for uplinks to connect to other switches or to servers. It is a Layer 3 switch, which means it is capable of routing traffic based on IP addresses and performing advanced networking tasks such as Virtual LANs (VLANs) and Quality of Service (QoS).

As a managed switch, this Item can be configured and managed using a web-based graphical user interface (GUI) or a command-line interface (CLI). This allows network administrators to set up and control the various features and settings of the switch, such as VLANs, port mirroring, and port security. The switch also supports a range of advanced features such as EnergyWise technology, which helps to reduce energy consumption and costs, and StackWise Plus, which allows multiple switches to be stacked together and managed as a single entity.

Features and Benefits

The Item is a member of the Cisco Catalyst 3750-X series of switches, which are designed to provide high performance in enterprise networking environments.

The switch has a forwarding rate of up to 95.2 Mpps (million packets per second) and a maximum stacking capacity of 9 switches, which allows it to support a large number of devices and handle a high volume of traffic. It also has a number of features to optimize performance in converged networks, where data, voice, and video traffic are all carried on a single network infrastructure. These features include Quality of Service (QoS) for prioritizing different types of traffic, and support for applications such as video conferencing.

In terms of physical performance, the Model has 12 SFP (small form-factor pluggable) ports, which are fiber optic ports that can be used to connect the switch to other network devices or to connect the switch to a network backbone. The switch is also equipped with EnergyWise technology, which allows it to monitor and control energy consumption of connected devices.
