Resiliency and High Availability of Switch

The Cisco Catalyst 9300 Series (C9300-48UN-A) is designed to provide resiliency and high availability for enterprise networks.

One key feature that contributes to the resiliency of this model is its support for stackability. This allows multiple switches to be connected together and managed as a single unit, which can help to improve resiliency and reduce the impact of a single switch failure. By connecting multiple switches together in a stack, if one switch fails, the other switches in the stack can continue to operate normally, ensuring that the network remains up and running.

Additionally, this part supports a number of high availability features such as redundancy and failover. This helps to ensure that there is always an alternate path for data to flow in the event of a failure. For example, the switch supports multiple uplink options, such as 10 Gigabit Ethernet or 40 Gigabit Ethernet, which allows for multiple paths for data to flow, providing redundancy in case of a failure.

The switch also supports various protocols that help to ensure high availability such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) which provide redundancy at the routing level.

Power and Innovation

The Cisco Catalyst 9300 Series 48-port 5Gbps Network Advantage switch is a high-performance, next-generation enterprise-class access switch that offers advanced features and functionality. It is designed to provide a secure, scalable, and simplified network infrastructure for businesses of all sizes. The switch provides 48 ports of 5Gbps Ethernet connectivity, with options for PoE+, UPOE, and Network Advantage Power. The switch also supports Cisco DNA Advantage software, which offers advanced security, network automation, and analytics capabilities. Additionally, the switch is designed to be energy-efficient, with features such as EnergyWise technology to help reduce power consumption. Overall, this part is a powerful and flexible option for businesses looking to upgrade their network infrastructure to support growing data and mobility needs.

Robust Security and Dynamic Quality

The Cisco Catalyst 9300 Series 48-port 5Gbps Network Advantage switch (C9300-48UN-A) includes robust security features to help protect against cyber threats. It features Cisco TrustSec technology, which allows for the creation of secure access policies based on user identity, device type, and location. Additionally, the switch supports advanced security features such as Cisco Identity Services Engine (ISE), which provides network access control (NAC) capabilities, and Cisco Secure Network Analytics, which allows for real-time monitoring and analytics of network security.

The switch also includes dynamic quality of service (QoS) features to help ensure that critical applications receive the bandwidth they need. The switch supports Cisco's Flexible NetFlow (FNF) technology, which allows for real-time monitoring and analysis of network traffic. Additionally, the switch supports Cisco's Quality of Service (QoS) policy configuration, which allows for the creation of policies to ensure that critical applications receive the necessary bandwidth and low-latency.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
