Description
CBS250-24T-4X
Overview
The Cisco Business 250 Series is the next generation of affordable smart switches that combine powerful performance and reliability with a complete suite of the features you need for a solid business network. These switches provide flexible management options, comprehensive security capabilities and Layer 3 static routing features far beyond those of an unmanaged or consumer-grade switch, at a lower cost than for fully managed switches.

| Layer 2 switching | |
| VLAN | Support for up to 255 active VLANs simultaneously
Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN |
| Voice VLAN | Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices |
| Layer 3 routing | |
| IPv4 routing | Wire-speed routing of IPv4 packets
Up to 32 static routes and up to 16 IP interfaces |
| IPv6 routing | Wire-speed routing of IPv6 packets |
| Layer 3 interface | Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
| Security | |
| Secure Sockets Layer (SSL) | SSL encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch |
| Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported. |
| IEEE 802.1X (authenticator role) | Remote Authentication Dial-In User Service (RADIUS) authentication, guest VLAN, single/multiple host mode, and single/multiple sessions |
| STP loopback guard | Provides additional protection against Layer 2 forwarding loops (STP loops) |
| Secure Core Technology (SCT) | Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received |
| Secure Sensitive Data (SSD) | A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plain text or encrypted is provided according to the user-configured access level and the access method of the user |
| Trustworthy systems | Trustworthy systems provide a highly secure foundation for Cisco products
Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC]) |
| Port security | Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses |
| RADIUS | Supports RADIUS authentication for management access. Switch functions as a client. |
| Storm control | Broadcast, multicast, and unknown unicast |
| DoS prevention | Denial-of-Service (DoS) attack prevention |
| Multiple user privilege levels in CLI | Level 1, 7, and 15 privilege levels |
| Access Control Lists (ACLs) | Support for up to 512 rules
Drop or rate limit based on source and destination MAC, VLAN ID or IPv4 or IPv6 address, IPv6 flow label, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag; ACL can be applied on both ingress and egress sides Time-based ACLs supported |

Product Details
-Layer 3 static routing
This capability allows you to segment your network into separate workgroups and communicate across VLANs without degrading application performance. As a result, you can manage internal routing with your switches and dedicate your router to external traffic and security, helping your network run more efficiently.
-Flexible and compact design
The sleek and compact design provide additional deployment flexibility, including outside wiring closet installation such as retail stores, open plan offices, and classrooms without disturbing the environment.
-Peace of mind and investment protection
Cisco Business 250 Series switches offer the reliable performance, investment protection, and peace of mind you expect from a Cisco switch. Complementary one-year access to our Small Business Support Center for ongoing support. Limited lifetime warranty with return to factory replacement keeps your business running smoothly.
