Advanced Security Features

The WS-C3850-12XS-S Cisco Catalyst 3850 12 Ports SFP+ Layer 3 Switch has a range of advanced security features that help to protect the network from potential security threats. Some of the key features include:

  • Cisco TrustSec: This feature provides advanced security capabilities such as identity-based access control and security group tagging, which allows administrators to assign different levels of access to different users and devices on the network.
  • Access Control Lists (ACLs): The switch supports the use of ACLs to control access to the network based on different criteria such as source and destination IP addresses, ports, and protocols. This allows administrators to implement granular access controls and to block unwanted traffic from entering the network.
  • Cisco Identity Services Engine (ISE): The switch can be integrated with the Cisco ISE to provide advanced network access control and identity-based security. This allows administrators to easily control access to the network based on user roles and to monitor network activity for potential security threats.
  • Cisco Advanced Malware Protection (AMP): The switch can be integrated with Cisco AMP to provide advanced malware protection, including the ability to detect and block malware in real-time.
  • Cisco Identity-based Firewall: The switch supports the use of Cisco Identity-based Firewall to provide context-aware security capabilities such as the ability to control access to the network based on the identity of the user and the device.
  • Secure Boot and Secure firmware image: The switch supports secure boot and secure firmware image which protect against malicious firmware modification and help ensure that only authorized firmware can be run on the switch.

All those features provide a strong layer of security to the WS-C3850-12XS-S Cisco Catalyst 3850 12 Ports SFP+ Layer 3 Switch and help to protect the network from potential security threats. Additionally, the switch supports a variety of security protocols such as IEEE 802.1X, which work to authenticate users and devices on the network, and Dynamic ARP Inspection (DAI), which helps to protect against ARP spoofing attacks.

High-Performance of 12 Ports Switch

The performance of a Cisco 12-port switch will depend on a number of factors, including the specific model of the switch, the networking standard it supports, the number of devices connected to it, and the presence of any physical obstructions.

In general, Cisco 12-port switches are capable of delivering fast networking speeds and have a number of advanced features that can help to improve their performance and reliability. These features may include things like Quality of Service (QoS), which allows you to prioritize certain types of traffic, and security features, such as encryption and authentication, to protect your network from unauthorized access.

If you are considering using a Cisco 12-port switch in your network, it is always a good idea to test its performance in your environment to ensure that it meets your needs. You can do this by connecting devices to the switch and measuring the data transfer speeds and stability of the connection.

Compatibility of SFP+ Switch

To ensure compatibility between a Cisco Catalyst 3850 12 ports SFP+ Layer 3 switch and other networking devices, you will need to consider the following factors:

  • Networking standard: The switch and the devices must support the same networking standard. For example, if the switch supports 802.11ac, the devices must also support 802.11ac.
  • Frequency band: The switch and the devices must support the same frequency band. For example, if the switch uses the 2.4 GHz frequency band, the devices must also support the 2.4 GHz band.
  • Speed: The switch and the devices must be capable of supporting the same speed. For example, if the switch has a maximum speed of 1.7 Gbps, the devices must also be capable of supporting speeds of at least 1.7 Gbps.
  • Connectors: The switch and the devices must have compatible connectors. For example, if the switch has SFP+ ports, the devices must have SFP+ modules or adapters to be compatible.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
