CBS220-24T-4G Cisco Business 220 Smart Switch, 24 Ports, Refurbished

Network Segmentation and Security

Network segmentation and security for the CBS220-24T-4G Cisco Business 220 Smart Switch can be achieved through a variety of means, including:

• Access Control Lists (ACLs): These can be used to restrict access to specific network segments or devices based on IP address, MAC address, or other criteria.
• Virtual LANs (VLANs): VLANs can be used to segment a network into multiple virtual subnets, allowing for greater control over traffic flow and security.
• Port Security: This feature allows for the configuration of specific security settings on individual switch ports, such as restricting access to certain MAC addresses or limiting the number of devices that can connect to a port.
• IEEE 802.1X Authentication: This protocol can be used to authenticate users and devices before granting them access to the network.
• Quality of Service (QoS): This feature allows for the prioritization of different types of network traffic, ensuring that critical applications receive the bandwidth they need to function properly.
• Network monitoring and management: The CBS220-24T-4G switch includes a built-in web interface and SNMP support for monitoring and managing the switch remotely.
• Advanced Encryption Standard (AES) to encrypt the data transmission between devices for secure communication.
• Firewall security features such as stateful packet inspection and denial of service (DoS) protection to prevent unauthorized access or network attacks.
• Implementing DHCP Snooping to prevent DHCP spoofing attacks.

By implementing these advanced security and network segmentation features, organizations can effectively secure their networks and ensure that critical applications and devices receive the resources they need to operate smoothly. Additionally, the SFP Uplink provides an option to connect to higher-speed devices or extend the network to other locations.

• Link Aggregation: This feature allows for the bundling of multiple switch ports together to increase available bandwidth and improve network performance.

By implementing these security and network segmentation features, organizations can effectively secure their networks and ensure that critical applications and devices receive the resources they need to operate smoothly.

Power over Ethernet (PoE) for Connected Devices

Power over Ethernet (PoE) is a technology that allows for the delivery of power to connected devices through the same Ethernet cable used for data transmission. This feature is particularly useful for devices such as IP phones, wireless access points, and security cameras, which may not be located near a power outlet.

The CBS220-24T-4G Cisco Business 220 Smart Switch is a PoE-compliant switch, meaning it can provide power to connected devices through the Ethernet cable. The switch supports PoE+ (IEEE 802.3at) with a total PoE power budget of 370W, allowing for the simultaneous powering of multiple devices.

To utilize PoE on the CBS220-24T-4G switch, the following steps can be taken:

• Configure the switch for PoE: The switch must be configured to enable PoE on specific ports. This can be done through the switch's web interface or through the command-line interface (CLI).
• Connect PoE-compliant devices: Connect PoE-compliant devices, such as IP phones or wireless access points, to the switch's PoE-enabled ports.
• Monitor power usage: The switch includes a built-in web interface and SNMP support for monitoring power usage on each PoE port.

By utilizing PoE on the CBS220-24T-4G switch, organizations can simplify the deployment and power management of connected devices, reducing the need for additional power outlets and cabling. This can save both time and money, while also providing a more reliable and efficient network infrastructure.
