Features And Specifications - Lenovo G8264 Product Manual

API that enables the network administrator to easily configure and manage virtual networks that control traffic
on a "per-flow" basis. It creates multiple independent virtual networks and related policies without dealing
with the complexities of the underlying physical network and protocols. The G8264 is also the ideal switch to
use with industry compliant OpenFlow controllers.
Transparent networking capability
With a simple configuration change to Easy Connect Mode, the RackSwitch G8264 becomes a transparent
network device, invisible to the core, eliminating network administration concerns of Spanning Tree Protocol
configuration/interoperability, VLAN assignments and avoids any possible loops.
By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by eliminating the
need to configure the typical access switch parameters.
