# interface name exceeds max length of 15

```text
networking[11980]: error: netlink: enp193s0f0np0.4001: cannot create vlan enp193s0f0np0.4001 4001: interface name exceeds max length of 15
```

Add “alias” to /etc/network/interfaces:

```text
auto enp193s0f0.4001
iface enp193s0f0.4001 inet manual
vlan-raw-device enp193s0f0np0
```

And restart network interfaces.
