Features and Specification of Managed Switch

The CBS250-48P-4X Cisco CBS350 Managed 48 Ports 2 Layer Switch is a flexible and scalable networking device that can adapt to the changing needs of a business or organization.

Flexibility refers to the ability of the switch to be configured and customized to meet different network requirements. For example, the CBS250-48P-4X has 48 ports that can be configured for different types of connections, such as Ethernet, Fast Ethernet, or Gigabit Ethernet. Additionally, the switch can be configured for different types of network topologies, such as a star, ring, or mesh topology, to support different types of network traffic.

Scalability refers to the ability of the switch to expand and grow as the network requirements change. The CBS250-48P-4X has four 10-Gigabit Ethernet ports that can be used to connect to other switches or routers, allowing the network to expand and grow as needed. Additionally, the switch can be configured to support virtual LANs (VLANs), allowing multiple networks to be created on the same switch, which allows for better organization and management of network traffic.

Management and Security Features

The Cisco CBS350 Managed 48 Ports 2 Layer Switch (CBS250-48P-4X) is a powerful and versatile network switch that offers a range of management and security features to help ensure the smooth and secure operation of your network.

Management features:

  • Web-based GUI: The switch can be easily configured and managed through a web-based graphical user interface, which allows for quick and easy access to all switch settings and configuration options.
  • CLI: The switch also supports a command-line interface (CLI), which allows for more advanced configuration and management options.
  • SNMP: The switch supports Simple Network Management Protocol (SNMP), which allows for the monitoring and management of the switch from a remote network management system.
  • LLDP: The switch supports Link Layer Discovery Protocol (LLDP), which allows for the discovery and identification of other devices on the network.
  • QoS: The switch supports Quality of Service (QoS) features, which allow for the prioritization of different types of network traffic to ensure that critical applications receive the bandwidth they need.

Security features:

  • Port security: The switch supports port security, which allows for the restriction of access to specific ports based on MAC addresses.
  • IEEE 802.1x: The switch supports IEEE 802.1x authentication, which allows for the authentication of users and devices before they are granted access to the network.
  • SSH/SSL: The switch supports Secure Shell (SSH) and Secure Sockets Layer (SSL) encryption, which provide secure remote management and access to the switch.
  • ACLs: The switch supports access control lists (ACLs), which allow for the restriction of access to specific network resources based on user roles and permissions.
  • DHCP snooping: The switch supports DHCP snooping, which helps to prevent DHCP spoofing attacks by only allowing DHCP requests and responses from trusted sources.
Quality of Service (QoS) Capabilities

The Cisco CBS250-48P-4X is a managed 48-port 2-layer switch that offers a variety of Quality of Service (QoS) capabilities to help ensure that network traffic is handled in a way that meets the needs of the different types of applications and users on the network.

One of the key QoS capabilities of the CBS250-48P-4X is the ability to prioritize different types of traffic based on their importance. This can be done using a variety of methods, such as setting priority levels for different types of traffic, using Quality of Service (QoS) policies to control how traffic is handled, or using traffic shaping to manage the flow of traffic.

Another important QoS capability of the CBS250-48P-4X is the ability to perform bandwidth management to ensure that all users have access to the resources they need. This can be done by setting bandwidth limits for different types of traffic, or by using traffic shaping to control the flow of traffic.

In addition, the CBS250-48P-4X also includes advanced QoS features such as congestion management, packet classification, and traffic policing to help ensure that network traffic is handled in a way that meets the needs of the different types of applications and users on the network.
