Assume

• We want to create an external network named VLANAXS205 with physnet1 as Interface name & 205 as VLAN ID

Technique

openstack network create \
  --provider-network-type vlan \
  --provider-physical-network physnet1 \
  --provider-segment 205 \
  --share \
  --disable-port-security \
  VLANAXS205

openstack port create \
  --network VLANAXS205 \
  --no-fixed-ip \
  --no-security-group \
  --disable-port-security \
  vlanaxs205-port2

openstack server add port 75bf5539-9e01-4d1a-9ac6-cf5df177b5db vlanaxs205-port2
