Features And Specifications - Lenovo Flex System EN2092 Product Manual

Simplified management

A key challenge is the management of a discrete network environment. The EN2092 1Gb Scalable
Switch supports a command-line interface (CLI) for integration into existing scripting and automation.
Network management can be simplified by using port profiles, topology views, and virtualization
management.
For more advanced levels of management and control, which can significantly reduce deployment
and day-to-day maintenance times, while providing in-depth visibility into the network performance
and operations of Lenovo switches. Plus, when leveraging tools like VMware vCenter Server or
vSphere, or Switch Center provides additional integration for better optimization.
