Creating a NIC segment without a VLAN
BMC Cloud Lifecycle Management 4.6.03 and later supports the NULL VLAN (VxLAN) on a virtual machine (not a physical server), which allows you to create a NIC segment without a VLAN in BMC Network Automation to use a VxLAN backport profile.
The following procedure describes how to set up a NULL VLAN in BMC Network Automation. You can then use the VLAN in BMC Cloud Lifecycle Management. For more information about editing address pools and NIC segments, see Editing a pod in the BMC Network Automation documentation.
To set up a NULL VLAN
- In BMC Network Automation, open the Pods page by navigating to Network > Virtual Data Center > Pods, and find the pod where you want to add the NULL VLAN.
- Click Add Address Pool, and add an address pool for the network.
- Click Add NIC Segment, and create a NIC segment with a NULL VLAN.
In the VLAN Name field on the following dialog box, select the first option with no value.
- Add a port type to the existing or new node, and on the Name Within Switch field, enter the VxLAN backport profile name, which is a preconfigured device.
- In BMC Cloud Lifecycle Management, synchronize the pod.
- Make sure that the name in the Name Within Switch field is VxLAN back port profile name.
This name must be pre-created on the network device (for example, switch) as the VxLAN back port profile.
Alternatively, you can create and configure a BMC Cloud Lifecycle Management environment with a NULL VLAN (VxLAN) from the Quick Start application. The process is similar to the fields discussed above.
When you create a pod and a network container on the Quick Start application and you enter the port group in the Port Group field, the VLAN ID field is pre-populated. Clear the VLAN ID field. Then, a NULL VLAN is passed to the associated network.
Physical server provisioning is not supported through a NULL VLAN.
NULL VLAN tips
When setting up a NULL VLAN, remember these tips:
- Make sure that, the port type name entered in the Name Within Switch in the BMC Network Automation pod is pre-created on the device before you synchronize the pod in BMC Cloud Lifecycle Management.
- Be aware that you cannot modify an existing NIC segment to use a NULL VLAN. If you want to use NULL VLAN, you must create a new NIC segment with a NULL VLAN.
- No changes are required for the network container blueprint, except that the network container must be reprovisioned to include the new node.
