BIGIP VE under Fusion Pro 10

Hi,

trying to install a BIGIP VE on VMware Fusion 10 (Trial). (I originally used Parallels for Mac, but I couldn't license it as it was identified as platform "")

I'm following this guide: https://devcentral.f5.com/articles/f5-developer-edition-installing-big-ip-on-vmware-fusion-8

To rule out mistakes, I applied this interface config: https://devcentral.f5.com/articles/vmware-fusion-custom-networking-for-big-ip-ve-lab

However, when I try to run

tmsh create net vlan external interfaces add { 1.1 { untagged } }

I get:

01070256: Requested VLAN member (1.1) is not valid

tmsh show net interface all

On my laptop:

$ ifconfig | grep vmnet
vmnet1: flags=8863 mtu 1500
vmnet2: flags=8863 mtu 1500
vmnet3: flags=8863 mtu 1500
vmnet4: flags=8863 mtu 1500
vmnet5: flags=8863 mtu 1500
vmnet6: flags=8863 mtu 1500
vmnet7: flags=8863 mtu 1500
vmnet8: flags=8863 mtu 1500
vmnet9: flags=8863 mtu 1500
