Power and Innovation of Layer 3 Switch

The CBS350-48T-4G is a Cisco 48-port L3 managed switch that is part of the Cisco 350X series. This series of switches is designed for small and medium-sized businesses and provides advanced features such as Layer 3 routing, Quality of Service (QoS), and security.

One of the key features of this part is its power and innovation. It has a built-in 4-port Gigabit Ethernet Small Form-Factor Pluggable (SFP) uplink, which provides high-speed connectivity options for fiber or copper uplinks. Additionally, it also supports PoE+ (Power over Ethernet Plus) which allows the switch to power devices such as IP phones, wireless access points, and security cameras without the need for additional power cables.

This product also supports Cisco's EnergyWise technology which allows for monitoring and controlling the energy consumption of connected devices. This can help to reduce energy costs and improve the overall efficiency of the network.

The switch also comes with a web-based management interface that makes it easy to configure and monitor the network. It also supports advanced security features such as access control lists (ACLs) and network segmentation to help protect the network from unauthorized access.

Remote Management Protocol

The CBS350-48T-4G is a Cisco 48-port Layer 3 managed switch that comes with 4 Gigabit Ethernet SFP uplink ports. This switch has the capability of Remote management protocol.

The Remote management protocol allows users to manage the switch from a remote location. This can be done using different management protocols like Telnet, SSH, SNMP, HTTP, and HTTPS.

  • Telnet: Allows users to remotely access the switch's command-line interface (CLI) via a Telnet client.
  • SSH: Allows users to remotely access the switch's CLI via a Secure Shell (SSH) client, which provides a secure and encrypted connection.
  • SNMP: Allows users to monitor and manage the switch using Simple Network Management Protocol (SNMP) commands.
  • HTTP/HTTPS: Allows users to remotely access the switch's web interface for management and configuration.

These protocols can be configured on the switch and can be accessed through a network management system or a web browser to remotely manage the switch.
