Introduction to the L3 Switch
The CBS250-8PP-D Cisco 8 Ports GbE 1U Rack Mountable L3 PoE+ Smart Switch is a network switch that provides 8 Gigabit Ethernet ports and supports Power over Ethernet Plus (PoE+). This switch can be mounted in a standard 1U rack and has L3 routing capabilities, which allows it to handle more advanced networking tasks such as IP routing, VLANs and Quality of Service (QoS). The switch also has "smart" features such as security, and management capabilities. This switch can be used in a variety of environments, including small and medium-sized businesses, enterprise branch offices, and campus networks to provide advanced features such as security, quality of service, and power over ethernet.
Power Options and Redundancy
The CBS250-8PP-D Cisco 8 Ports GbE 1U Rack Mountable L3 PoE+ Smart Switch supports Power over Ethernet Plus (PoE+) on all 8 ports, which allows devices such as IP phones and wireless access points to receive power and data over a single Ethernet cable. The switch also has an internal power supply, which provides a redundant power option.
The switch supports redundancy options like Link Aggregation Control Protocol (LACP) which allows multiple physical connections to be bundled together to form a single logical link, providing redundancy and increased bandwidth. Additionally, it supports the Spanning Tree Protocol (STP) which ensures a loop-free topology for your network and provides redundancy in case of a link failure.
It also provides advanced security features such as Access Control List (ACL) for controlling network access, and Advanced Encryption Standard (AES) for securing data transmission.
Routing and Switching Protocols
The CBS250-8PP-D Cisco 8 Ports GbE 1U Rack Mountable L3 PoE+ Smart Switch supports various routing and switching protocols to provide advanced networking capabilities.
In terms of routing protocols, it supports Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) which are used to exchange routing information between routers in a network. It also supports Protocol Independent Multicast (PIM) for efficient multicast routing.
In terms of switching protocols, the switch supports Link Aggregation Control Protocol (LACP) which allows multiple physical connections to be bundled together to form a single logical link, providing redundancy and increased bandwidth. It also supports the Spanning Tree Protocol (STP) which ensures a loop-free topology for your network and provides redundancy in case of a link failure.
Additionally, it supports Virtual Local Area Network (VLAN) for segmenting the network and Quality of Service (QoS) for prioritizing network traffic.
It also provides advanced security features such as Access Control List (ACL) for controlling network access, and Advanced Encryption Standard (AES) for securing data transmission, making it a robust and secure solution for small and medium-sized businesses and enterprise branch offices.

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).
The unmanaged switches offer fixed configurations 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.
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 refer to switches that possess more features than those 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 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.
