Cisco C9200-48PB Catalyst 9200 Series switches

The Cisco C9200-48PB is a high-performance switch in the Catalyst 9200 series, designed for enterprise and service provider networks.

Here is a detailed introduction of Cisco C9200-48PB:

• Number of Ports: It is equipped with 48 ports, providing a high-density connection solution for various devices such as servers, IP phones, wireless access points, and workstations. These ports support Ethernet connections, enabling high-speed data transfer within the network.

• Port Type: The "PB" in the model name indicates that these ports support PoE+ (Power over Ethernet Plus). PoE+ technology allows the switch to supply power to connected devices over the Ethernet cable, eliminating the need for separate power supplies for each device. This is particularly useful for powering devices like wireless access points and IP cameras, which may be difficult to access or require additional power infrastructure. Each PoE+ port can provide a certain amount of power, typically up to 30W per port, depending on the specific model and power budget of the switch.

Performance

• Switching Capacity: The C9200 - 48PB offers a high switching capacity, which refers to the amount of data that the switch can handle simultaneously. This ensures smooth and efficient operation even under heavy network traffic conditions. The specific switching capacity may vary depending on the model and configuration, but it is generally designed to meet the demands of modern enterprise networks with high data throughput requirements.

• Packet Forwarding Rate: It also has a high packet forwarding rate, which is the number of data packets that the switch can process and forward per second. A high packet forwarding rate is crucial for maintaining low latency and ensuring that network applications run smoothly. The C9200 - 48PB is capable of forwarding packets at a fast rate, allowing for quick and efficient data transfer between devices connected to the switch.

Features

• Redundancy: To ensure high availability and reliability, the C9200-48PB supports redundant power supplies and fans. This means that if one power supply or fan fails, the switch can continue to operate normally using the redundant component. Redundancy helps to prevent network outages and ensures that critical network services remain operational.

• Quality of Service (QoS): The switch supports QoS, which allows network administrators to prioritize different types of network traffic. For example, real-time applications such as voice and video can be given higher priority over less time-sensitive traffic like file downloads. QoS helps to ensure that critical applications receive the necessary bandwidth and low latency to operate smoothly, even during periods of high network congestion.

• Security: The C9200 - 48PB provides several security features to protect the network from unauthorized access and potential threats. It supports access control lists (ACLs), which allow administrators to define rules for permitting or denying network traffic based on source and destination IP addresses, ports, and protocols. Additionally, the switch may support features such as 802.1X authentication, which requires devices to authenticate before accessing the network, and DHCP snooping, which helps prevent unauthorized DHCP servers from being connected to the network.

• Virtual Local Area Networks (VLANs): The switch supports VLANs, which allow network administrators to segment the network into multiple virtual networks. VLANs provide enhanced security and network management by isolating different departments or user groups from each other. For example, a company can create separate VLANs for its sales, marketing, and finance departments, ensuring that traffic between these departments is restricted and secure.

• Stacking: The C9200 - 48PB may support stacking, which allows multiple switches to be connected together and managed as a single unit. Stacking provides additional port density and redundancy, as well as simplified management. By stacking multiple switches, network administrators can increase the overall capacity of the network and ensure that there is no single point of failure.

Management and Configuration

• Command Line Interface (CLI): The C9200-48PB can be managed through a CLI, which provides a powerful and detailed way to configure and manage the switch. The CLI allows experienced network engineers to perform advanced configuration tasks and customize the switch's settings according to specific network requirements.

• Web-Based Interface: In addition to the CLI, the switch also offers a web-based graphical user interface (GUI). The web interface provides an intuitive and easy-to-use interface for network administrators who may not be familiar with the CLI. It allows for quick and convenient configuration of the switch's basic settings, as well as monitoring of network performance and status.

• Simple Network Management Protocol (SNMP): The C9200-48PB supports SNMP, which allows it to be integrated with existing network management systems. SNMP enables centralized monitoring and management of the switch, allowing network administrators to view and manage the switch's configuration, performance, and status from a single console.

Applications

• Enterprise Networks: The Cisco C9200-48PB is well-suited for use in enterprise networks, where it can provide high-speed connectivity, reliability, and security. It can be used to connect servers, workstations, IP phones, and wireless access points, enabling seamless communication and data transfer within the enterprise.

• Service Provider Networks: Service providers can also benefit from the C9200 - 48PB's high-performance capabilities. It can be used to build reliable and scalable networks for providing services such as broadband internet access, voice over IP (VoIP), and video conferencing.
