| | 15 | = Steps to reproduce |
| | 16 | |
| | 17 | 1. In the macOS Terminal, create a tagged VLAN on Ethernet named `vlan1387`: |
| | 18 | {{{ |
| | 19 | ~ root# ifconfig vlan1387 create |
| | 20 | ~ root# ifconfig vlan1387 vlan 1387 vlan en0 |
| | 21 | }}} |
| | 22 | 2. Configure a guest to use it. Under Network → Adapter 1: |
| | 23 | |
| | 24 | |||| ☑ Enable Network Adapter || |
| | 25 | || Attached to: || Bridged Adapter || |
| | 26 | || Name: || vlan1387 || |
| | 27 | 3. Start the guest. Obtain the error dialog quoted above. Notice that "vlan1387" has been truncated in "HostInterfaceNetworking-vlan138". |
| | 28 | |
| | 29 | If I try the same steps with a shorter interface name (e.g. `vlan0`), it works. |
