OpenStack CLI enables you to manage the topology between compute nodes and SLX devices. Physical Network Topology extension provides a Neutron CLI for the OpenStack administrator to manage links between SLX devices and Compute NICs. Neutron has an abstract for physical network called Provider Network.
Extreme Topology plug-in provides efa-link-mapping command to configure and setup the topology. The efa-link-mapping feature enables scaling in and scaling out of compute nodes. For more information about scaling in and scaling out of compute nodes, see Scale-in and Scale-out of Compute Nodes.
