Field	Type	Description	Value(s)
`name`	string	Alias for the link.

Don't use system interface names like "eth0", "ens3", "enp0s2", etc. as those may conflict with existing physical interfaces.

The name can contain a single integer format verb (%d) to create multiple aliases from a single config document. When a format verb is detected, each matched link receives a sequential alias (e.g. net0, net1, ...) based on hardware address order of the links. Links already aliased by a previous config are automatically skipped. <details><summary>Show example(s)</summary>{{< highlight yaml >}} name: net0 {{< /highlight >}}{{< highlight yaml >}} name: private {{< /highlight >}}{{< highlight yaml >}} name: net%d {{< /highlight >}}</details> | | |selector |<a href="#LinkAliasConfig.selector">LinkSelector</a> |Selector to match the link to alias.

When the alias name is a fixed string, the selector must match exactly one link. When the alias name contains a format verb (e.g. net%d), the selector may match multiple links and each match receives a sequential alias. If multiple selectors match the same link, the first one is used. | |
