The Cisco Small Business SF220-48 is a managed switch that provides a secure and reliable network foundation for small businesses. It offers 48 Fast Ethernet (10/100 Mbps) ports for standard device connections, along with two Gigabit Ethernet combo ports (RJ45/SFP) and two dedicated Gigabit SFP ports for high-speed uplinks to other switches or servers. With a switching capacity of 17.6 Gbps and a forwarding rate of 13.1 Mpps, this switch handles network traffic efficiently. The SF220-48 is also equipped with a MAC address table of 8,000 entries and supports up to 256 active VLANs for network segmentation and security. This switch includes robust features typically found in more expensive models, such as basic Layer 3 static routing to help manage traffic between different VLANs and Quality of Service (QoS) to prioritize data for real-time applications like voice and video. Its security features, including Access Control Lists (ACLs) and 802.1X port security, protect the network from unauthorized access. The switch is rack-mountable, powered by an internal power supply, and can be managed through a user-friendly web interface, a command-line interface (CLI), or SNMP. The SF220-48 also supports Jumbo Frames up to 10 KB, helping to improve performance for large data transfers.
