Cisco C9200-24PB Catalyst 9200 Series switches

The Cisco C9200-24PB is a high-performance switch in the Catalyst 9200 series, designed for enterprise and service provider networks.

Here is a detailed introduction:

Ports of Cisco C9200-24PB

• Number of Ports: It is equipped with 24 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 C9200-24PB 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 C9200-24PB 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 C9200-24PB 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 C9200-24PB 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 C9200-24PB 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.
