- DHCP Snooping - This feature helps to prevent malicious DHCP servers from being able to distribute incorrect IP addresses to clients on your network.
- Dynamic ARP Inspection (DAI) - This feature helps to prevent ARP spoofing attacks by ensuring that ARP packets have a valid IP-to-MAC address binding.
- IP Source Guard - This feature helps to prevent IP spoofing by ensuring that packets have a valid IP source address.
- Cisco IOS Firewall - This feature provides stateful firewall protection for your network.
- Cisco IOS Intrusion Prevention System (IPS) - This feature helps to prevent network attacks by identifying and blocking malicious traffic.
- Secure Shell (SSH) - This feature provides secure remote access to the switch for management and configuration purposes.
- Secure Copy (SCP) - This feature allows you to securely transfer files to and from the switch.
These features work together to provide a comprehensive security solution for your network, helping to protect it from potential threats.

About Refurbished Products
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.
