Key Features and CapabilitiesPower Over Ethernet Plus (PoE+)
The inclusion of PoE+ Capabilities in the Cisco C9300L-24P-4G-E is a game-changer for organizations looking to simplify their network architecture. PoE+ enables the switch to deliver both data and electrical power over the Ethernet cable, eliminating the need for separate power sources for connected devices.
Network Advantage Layer3 (L3) Support
The Network Advantage feature denotes advanced capabilities in terms of Layer 3 (L3) support. This implies that the switch can operate at the network layer of the OSI model, providing enhanced routing and scalability. Businesses with complex networking requirements can leverage the L3 support to achieve a more sophisticated and efficient network architecture.
Modular Design
The term Modular signifies the switch’s adaptability and scalability. This design allows for the addition of expansion modules, tailoring the switch to specific needs. The flexibility offered by modular switches is invaluable in environments where the network infrastructure must evolve alongside organizational growth.
Twisted Pair and Optical Fiber Connectivity
The switch supports both modular twisted pair and optical fiber connectivity, offering versatility in how devices can be connected. Twisted pair connections are ideal for short-distance communication, while optical fiber connections are well-suited for longer distances and environments where electromagnetic interference is a concern.
Security and Access Control of Switch
The C9300L-24P-4G-E Cisco Catalyst 9300L 24-port Managed Switch includes advanced security and access control features to protect enterprise networks against malicious activity and unauthorized access. Some of the key security features include:
- Cisco TrustSec: This feature allows for network segmentation and secure communication between devices on the network. It uses security group tags (SGTs) and security group access control lists (SGACLs) to control access to specific parts of the network.
- 802.1X Authentication: The switch supports 802.1X authentication, which allows for the use of a variety of authentication methods, such as EAP-TLS, PEAP, and EAP-FAST, to control access to the network based on user credentials.
- Advanced Malware Protection (AMP): It helps to detect and prevent malware from entering the network by analyzing and blocking malicious files and traffic.
- Firewall policies: The switch supports firewall policies, which allow administrators to control traffic flow and protect against malicious activity.
- Access Control Lists (ACLs): The switch supports the use of ACLs, which allow administrators to control access to specific network resources based on IP address, protocol, and other criteria.
- Intrusion Prevention System (IPS): It examines all incoming and outgoing network traffic and identifies, logs, and blocks malicious traffic in real-time.
Deployment Considerations
Before implementing the Cisco C9300L-24P-4G-E in a network, certain deployment considerations should be taken into account.
Network Topology
Understanding the network topology is crucial for optimal deployment. The 4X1G uplinks provide flexibility in connecting to different parts of the network, and the Layer 3 support enables efficient routing. Careful consideration of the network layout and traffic patterns will help maximize the benefits of the switch.
Power Requirements
As a PoE+ switch, the Cisco C9300L-24P-4G-E requires sufficient power to support connected devices. Organizations should ensure that the power infrastructure can accommodate the additional power demands, especially in scenarios where a large number of PoE+ devices will be deployed.
Future Scalability
The modular design of the Cisco C9300L-24P-4G-E allows for future scalability. Organizations should assess their potential growth and expansion plans to determine if the switch can accommodate evolving networking needs. Investing in modular components that align with future requirements can extend the lifespan and value of the networking infrastructure.

Future-Proof Networking
The modular design of the Cisco C9300L-24P-4G-E ensures that organizations can adapt to changing technological landscapes. As network requirements evolve, additional modules can be seamlessly integrated, future-proofing the network infrastructure and minimizing the need for costly upgrades.
Cost-Efficiency Through PoE+
The Power Over Ethernet Plus (PoE+) capability of this switch contributes to cost efficiency by eliminating the need for separate power sources for connected devices. This not only simplifies the cabling infrastructure but also reduces installation and maintenance costs.
Enhanced Performance with Network Advantage
The Network Advantage Layer3 (L3) support enhances the switch’s performance, making it suitable for complex networking scenarios. Organizations with demanding requirements, such as extensive routing and scalability needs, can benefit significantly from the advanced capabilities offered by the Network Advantage feature.
Versatile Connectivity Options
The support for both modular twisted pair and optical fiber connectivity provides organizations with flexibility in designing their network topology. This versatility is crucial for addressing diverse connectivity needs, whether within a data center, across multiple floors of a building, or in an outdoor environment.
Redundancy and Scalability
The C9300L-24P-4G-E Cisco Catalyst 9300L 24-port Managed Switch is designed to provide redundancy and scalability for enterprise networks. Some of the key features that support redundancy and scalability include:
- StackWise-480 technology: This technology allows for the switch to be stacked with other switches in the Cisco Catalyst 9300L series, providing increased scalability and ease of management. By stacking multiple switches together, the network can be expanded as needed without requiring additional cabling or management interfaces. Furthermore, StackWise-480 technology provides power redundancy, which prevents a single point of failure and provides continued power to the network in case of a power supply failure.
- Link Aggregation Control Protocol (LACP): This protocol allows for the bundling of multiple physical interfaces together to form a single logical interface, increasing the bandwidth and providing redundancy. By bundling multiple interfaces together, if one interface fails, the traffic can be automatically directed to another interface, ensuring continuous communication on the network.
- Redundant Power Supply: The switch supports both AC and DC power supplies and also allows for the use of external power supplies, giving users the flexibility to choose the most efficient power options for their specific network environment. This provides redundancy, which prevents a single point of failure and provides continued power to the network in case of a power supply failure.
- High Availability: The switch supports features such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) which ensures that if a switch or router fails, another one takes over immediately to keep the network running without interruption.
