For VMware Integrated OpenStack deployments based on NSX, the API access, Management, Transport, and External network each require a separate and dedicated VLAN.
Request that your network administrator prepare the necessary VLANs.
VLAN |
Description |
---|---|
API Access network |
Provides access for users to the OpenStack services through APIs or the VMware Integrated OpenStack dashboard.
|
External |
Provides external user access to the instances.
|
Management network |
Carries traffic among the management components.
If you are deploying the NSX Manager and NSX Controller VMs on the Management cluster, you must trunk their hosts to the Management network. |
Metadata-service |
The metadata-service network enables new OpenStack instances to access and run customization scripts made available by the Nova metadata service, which is hosted by the OpenStack controllers. |
Transport |
Carries traffic among the OpenStack instances.
Important:
The Maximum Transmission Unit (MTU) settings for the Transport VLAN must be configured to support 1600 bytes. See the Knowledge Base at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2093324. |
