| 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]) |

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 provides 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. Complimentary 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.
