Fault tolerance
The NE2572 RackSwitch offers redundant hot-swap hardware components, learns alternate routes
automatically, and performs faster convergence if there is a link, switch, or power failure.
Seamless interoperability
RackSwitch switches perform seamlessly with other vendors' upstream switches.
Automated VM-aware network provisioning
The Lenovo CNOS Network Policy Agent, a ThinkAgile Network Orchestrator feature, gives
increased visibility of the virtual infrastructure, including VM and virtual network information. It
provides automated VM-aware provisioning by automatically configuring VLANs in the physical
network based on the auto-discovered virtual network topology. The agent also performs ongoing
dynamic updates to the physical network configuration in response to new VMs, updated VMs,
and deleted VMs and virtual networks, eliminating errors with manual configuration.
Note: The Network Policy Agent works with the Nutanix Acropolis Hypervisor (AHV) and Nutanix
Acropolis software version 5.0.2 or higher (excluding 5.1.2).
Pro-active congestion monitoring
Telemetry enables continuous monitoring of networking devices to detect potential congestion
problems, such as packets dropped by the switch when ports are being used close to their line rate
or switch buffers are being temporarily overflown (for example, in case of microbursts).
Zero Touch Provisioning
Zero Touch Provisioning (ZTP) enables a switch to automatically provision itself using the resources
available on the network, without manual intervention. ZTP automatically handles the process of
upgrading the switch software image and installing configuration files.
Python Scripting
Network administrators can create and execute local Python scripts on switches to make small
programs that allow a switch to automatically provision itself, perform fault monitoring, upgrade the
image files, or auto-generate configuration files. Administrators can also implement version control
systems, automatically generate alerts, create custom logging tools, and automate the
management of network devices.
REST API Programming
The Lenovo REpresentational State Transfer (REST) Application Program Interface (API) enables
network administrators to remotely configure and manage a Lenovo switch using REST and
HyperText Transfer Protocol (HTTP). It also allows switch management integration into management
applications, such as Lenovo xClarity.
