Cisco UCS Director and Cisco ACI Have a Common Understanding of EPG
Characteristics
After Cisco ACI has created the network container, it informs Cisco UCS Director
and the virtualization manager about the network characteristics of each EPG so that
they can discover the new networks, and so that Cisco UCS Director can deploy
computing and storage resources in the network container.

Cisco UCS Director needs to know the endpoint characteristics for two reasons:
• It needs to configure port profiles so that it can direct Cisco UCS to configure
• It needs to configure port profiles so that it can direct Cisco UCS to configure
physical servers with NIC configurations that Cisco ACI recognizes as belonging
to one of the newly created EPGs.

• It needs to configure port profiles to match port groups in virtualization managers
such as VMware vSphere so that the virtualization manager and Cisco UCS can
coordinate network connectivity to Cisco ACI.

their virtual machines to become members of the newly defined endpoint groups.

Cisco UCS Director Deploys Virtual Machines
Using information from the application profile, Cisco UCS Director deploys the virtual
machines dictated by the application profile into the network container. In the case in
the example described so far, it will deploy four web servers into the web EPG, and
two application servers into the app EPG.

Because of the coordination described in the previous step, Cisco UCS Director
understands the virtual networks created by the virtualization manager and uses that
knowledge to interface with the EPG in Cisco ACI Cisco UCS Director coordinates
the creation of virtual machines and vNICs with port groups configured to match
EPG requirements. This coordination allows Cisco ACI to automatically recognize the
new virtual machine as belonging to a specific EPG. It creates the virtual machines
