Performance of Switch

The CBS350-48T-4G is a Cisco Catalyst 350 Series switch that has 48 Gigabit Ethernet ports and 4 Gigabit Ethernet SFP uplink ports. As a L3 managed switch, it has the capability to handle advanced routing protocols such as OSPF, EIGRP and ISIS, and provides advanced features such as Quality of Service (QoS), Access Control Lists (ACLs), and Link Aggregation Control Protocol (LACP).

This switch is designed for high-performance and high-density environments and can provide a high level of security, scalability, and reliability. It supports advanced traffic management and can prioritize time-sensitive data to ensure that critical applications receive the bandwidth they need.

Additionally, this switch also support for advanced security features such as IEEE 802.1X, DHCP snooping, and IP Source Guard and supports for advanced management features such as SNMP, RMON, and NetFlow.

In summary, this part is a powerful and versatile switch that can handle the demands of high-performance networks and provide advanced features for security, traffic management, and network management.

Power and Innovation for Layer 3 Managed Switch

The Cisco CBS350-48T-4G is a Layer 3 Managed switch that has 48 Gigabit Ethernet ports and 4 SFP (Small Form-Factor Pluggable) ports. It is a member of the Cisco Catalyst 350X series, which is designed for small to medium-sized businesses and enterprise branch offices.

One of the key features of this product is its ability to provide advanced Layer 3 routing capabilities, such as OSPF and EIGRP. This allows the switch to support more complex network topologies and to provide enhanced network segmentation and traffic management.

In addition to its routing capabilities, this part also offers a number of other advanced features, including Quality of Service (QoS) for traffic prioritization, access control lists (ACLs) for security, and Link Aggregation Control Protocol (LACP) for increased bandwidth.

Another feature of this product is its power innovation, it can support both standard AC and DC power inputs, which allows the switch to be deployed in a variety of environments, including those with limited AC power availability.

Furthermore, this item support the Cisco DNA Advantage, which provides a comprehensive set of network management and automation tools that helps customers simplify their network operations, reduce costs and improve security.

Remote Management Protocol

The CBS350-48T-4G is a Cisco 48-port L3 managed switch that supports remote management protocols such as Simple Network Management Protocol (SNMP), Cisco Discovery Protocol (CDP), and Telnet.

SNMP is a widely used protocol for managing and monitoring network devices. It allows administrators to monitor the switch's performance, configuration, and other parameters through SNMP management software.

CDP is a Cisco proprietary protocol that allows network devices to share information about other directly connected Cisco equipment, including device type, uptime, IOS version, and IP address.

Telnet is a remote login protocol that allows administrators to access the switch's command-line interface remotely over the network. It allows administrators to configure, troubleshoot, and manage the switch remotely.

Additionally, it also support Remote management protocols such as HTTPS, SSH, and SCP, which are also widely used for secure remote management of network devices.
