After you configure the vNICs on the server network adapter, you might have to consider the following to complete the configuration.
Reboot the server and reset the server network adapter.
Reload the drivers.
See the documentation for your specific server network adapter for details.
When the configuration is complete, the server network adapter and the switch re-establishes a link and performs the initial handshake and negotiation process. The server network adapter and the switch also establish higher level control plane connectivity using the Virtual Interface Configuration (VIC) protocol.
The VIC protocol allows you to provision and manage virtual interfaces on a remote device.
When the VIC protocol connectivity is established, the server network adapter requests that the switch create a Vethernet interface for each vNIC that is configured on the server network adapter. The server network adapter also passes the following attributes over the uplink in addition to the create Vethernet interface request:
The switch responds by creating a Vethernet interface for each vNIC on the server network adapter and associates the port-profile and channel number to the Vethernet interface.
The server bootup process might be held at the BIOS configuration phase until the Vethernet creation has completed. After the Vethernet is created, the bootup process resumes and the operating system is loaded. See to the documentation for your specific adapter for details.
The global configuration command, no vethernet auto-create, stops the Vethernet interfaces from being automatically created. If the switch is not configured with the vethernet auto-create command, you must configure the Vethernet interfaces manually with the appropriate binding and port-profile configurations.
Vethernet interfaces created by the switch are numbered automatically as they are created. These vethernet numbers start from 32769. The switch picks the lowest unused number when creating a Vethernet interface.
When you manually create Vetethernet interfaces, you may select any number for the Vethernet. However, as a best practice, you should choose a number that is less that 32678.
