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.
