Note
Untagged ports that are added to a VLAN are automatically
removed from their current untagged VLAN assignment. Untagged
ports that are removed from a VLAN are returned to the
Default_VLAN.

assigning it to another VLAN leaves the port as an untagged
member of no VLAN.
The modified VLAN is now ready for network operations.
