Description
Advanced Features of 48 Ports Switch
The SF220-48-K9-NA Cisco Small Business Smart Plus SF220-48 is a 48-port SFP (Small Form-Factor Pluggable) PoE+ (Power over Ethernet Plus) manageable Layer 2 Ethernet switch. Some of its advanced features include:
- PoE+: The switch supports PoE+ with a total power budget of 370W, allowing devices such as IP phones and wireless access points to be powered directly from the switch, eliminating the need for additional power supplies.
- Layer 2 switching: The switch supports Layer 2 switching, providing advanced features such as VLANs, Quality of Service (QoS), and Link Aggregation Control Protocol (LACP).
- SFP ports: The switch includes 48 SFP ports, which support fiber connectivity and can be used for uplinks to other switches or to connect to servers.
- Management: The switch can be managed through a web interface, SNMP (Simple Network Management Protocol), or through a command-line interface (CLI) using Telnet or SSH.
- Security: The switch supports advanced security features such as Access Control Lists (ACLs) and port security to help protect your network from unauthorized access.
- Energy efficient: The SF220-48-K9-NA supports Energy Efficient Ethernet (EEE) which reduces power consumption when the link is in low-utilization state, and also supports IEEE 802.3az Energy Efficient Ethernet (EEE) standard.
Scalable and High-Performance
The SF220-48-K9-NA Cisco Small Business Smart Plus SF220-48 is designed to be scalable and high-performance, making it well-suited for small and medium-sized businesses. Some of its features that contribute to its scalability and performance include:
- High-performance switching: The switch supports wire-speed switching, which means it can process packets at line rate without any loss of performance. This makes it well-suited for high-bandwidth applications such as video streaming and VoIP.
- Scalable network design: The switch supports VLANs, Quality of Service (QoS), and Link Aggregation Control Protocol (LACP), which allows for a scalable network design. This allows you to segment your network into different VLANs for security and performance reasons, and also allows for the creation of high-bandwidth links between switches.
- Port density: With 48 ports, the SF220-48-K9-NA offers a high port density, allowing for a large number of devices to be connected to the switch.
- Fiber connectivity: The switch includes 48 SFP ports, which support fiber connectivity and can be used for uplinks to other switches or to connect to servers. This allows for a scalable and high-performance network design, as fiber connections are faster and more reliable than copper connections.
- PoE+: The switch supports PoE+ with a total power budget of 370W, allowing devices such as IP phones and wireless access points to be powered directly from the switch, eliminating the need for additional power supplies. This allows for a more scalable and cost-effective network design.
Security and Access Control
The SF220-48-K9-NA Cisco Small Business Smart Plus SF220-48 includes several security and access control features to help protect your network from unauthorized access and potential threats. These features include:
- Access Control Lists (ACLs): The switch supports ACLs, which allow you to define rules for controlling access to the network. These rules can be based on things like IP addresses, protocols, and port numbers.
- Port security: The switch supports port security, which allows you to restrict access to a specific port or set of ports based on MAC addresses. This can help prevent unauthorized devices from connecting to your network.
- SSH and SSL support: The switch supports SSH (Secure Shell) and SSL (Secure Sockets Layer) for secure management and access to the switch. This allows you to securely access the switch from remote locations and ensures that sensitive information, such as login credentials and configuration data, is protected during transmission.
- SNMPv3: The switch supports SNMPv3, which provides secure access to device information and management via SNMP. This provides secure access to device information, and reduces the risk of unauthorized access.
- IEEE 802.1x: The switch supports IEEE 802.1x, which is a standard for port-based network access control. It allows for the authentication of users connecting to the network, and also helps to prevent unauthorized access by restricting network access to only authenticated users.
- Private VLAN: The switch supports Private VLAN, which allows you to segment your network into different VLANs for security and performance reasons. This can help to prevent unauthorized access by isolating sensitive data or systems from the rest of the network.
