The Cisco CBS220-24P-4G is a 24-port Gigabit Ethernet switch with 4 SFP+ ports. It is designed for small and medium-sized businesses that need a reliable and affordable switching solution. The CBS220-24P-4G offers a variety of features, including:
The Cisco CBS220-24p-4g is equipped with 24 Gigabit Ethernet ports, allowing you to connect a variety of devices such as computers, servers, IP phones, and access points. These ports support auto-negotiation and auto-sensing, ensuring compatibility with both 10/100/1000 Mbps Ethernet devices.
One of the key features of the CBS220-24p-4g switch is Power over Ethernet (PoE) support. It provides power to PoE-enabled devices such as IP phones, wireless access points, and IP cameras, eliminating the need for separate power supplies or adapters. The switch can deliver up to 30 watts of power per PoE port, which is compliant with the IEEE 802.3af/at standards.
The switch also includes four SFP (Small Form-factor Pluggable) uplink ports, which allow for high-speed fiber connectivity. These SFP ports can be used for connecting to other switches or for extending the network over longer distances using fiber optic cables.
In terms of management, the Cisco CBS220-24p-4g offers a user-friendly web-based interface that enables easy configuration and monitoring of the switch. It supports features such as VLANs (Virtual Local Area Networks), QoS (Quality of Service), and link aggregation, which help optimize network performance and ensure reliable data transmission.
Additionally, the Cisco CBS220-24p-4g provides enhanced network security features. It supports port security, which allows you to restrict access to specific ports based on MAC addresses. It also offers features like DHCP snooping and IP-MAC binding, which help prevent unauthorized access and mitigate potential security threats.
Furthermore, the switch supports IPv6, ensuring compatibility with the latest networking protocols and future-proofing your network infrastructure.

| Security | . |
| ACLs | Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, Transmission Control Protocol (TCP)/ User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, TCP flag Support up to 512 rules |
| Port security | Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses |
| IEEE 802.1X (authenticator role) | 802.1X: Remote Authentication Dial-in User Service (RADIUS) authentication; guest VLAN; Single-host, multiple-host, and multisession mode |
| RADIUS, TACACS+ | Supports RADIUS and Terminal Access Controller Access Control System (TACACS) authentication; switch functions as a client |
| MAC address filtering | Supported |
| Storm control | Broadcast, multicast, and unknown unicast |
| DoS protection | DOS attack prevention |
| STP Bridge Protocol Data Unit (BPDU) Guard | This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. |
| Spanning Tree Loop Guard | This feature provides additional protection against Layer 2 forwarding loops (STP loops). |
| Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported. |
| Secure Sockets Layer (SSL) | SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
| QoS | . |
| Priority levels | 8 hardware queues per port |
| Scheduling | Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS) |
| Class of service | Port-based; 802.1p VLAN priority-based; IPv4/v6 IP precedence, Type of Service (ToS), and DSCP-based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS |
| Rate limiting | Ingress policer; egress shaping and rate control; per VLAN, per port, and flow-based |
| Congestion avoidance | A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization. |
