About Migrating a VDS Domain to Cisco ACI Virtual Edge
If you have VMware VDS domains configured, you can migrate that domain to Cisco ACI Virtual Edge. The migration enables you to take advantage of Cisco ACI Virtual Edge features. These include the ability to use VXLAN encapsulation and Distributed Firewall.
When you migrate a VDS domain, Cisco APIC creates inside and outside and port groups on the DVS in vCenter. The domain appears as a Cisco ACI Virtual Edge domain. However, you can choose to have some endpoints operate in native VDS mode and other operate in AVE (Cisco ACI Virtual Edge) mode. That is, endpoints are switched through the VDS or the Cisco ACI Virtual Edge.
You can migrate VMware VDS domains to Cisco ACI Virtual Edge by using the Cisco APIC GUI, the NX-OS style CLI, or REST API.
Changing the switching mode from native to AVE (Cisco ACI Virtual Edge) on an EPG requires changing the underlying switching platform from regular VMware DVS to Cisco ACI Virtual Edge. It also requires moving all the associated ports from DVS to Cisco ACI Virtual Edge.
This operation requires reprogramming of the port group associated with that EPG. That in turn requires a vCenter operation. It make take a few seconds for this operation to complete and for ports to show up in forwarding state on the Cisco ACI Virtual Edge switching platform. It length of time depends on the vCenter load as well as the number of endpoints that reside on the EPG that is being moved from native to AVE mode.
