Move an Untagged Interface to Another VLAN

The no untagged interface command removes the untagged interface from a port-based VLAN and places the interface in the Default VLAN. You cannot use the no untagged interface command in the Default VLAN. The following example shows the steps and commands to move an untagged interface from the Default VLAN to another VLAN.

To determine interface status, use the show vlan command. Interface (gi 3/2) is untagged and in the Default VLAN (vlan 1). In a port-based VLAN (vlan 4), use the untagged command to add the interface to that VLAN. The show vlan command output displays the interface’s changed status (gi 3/2). Because the Default VLAN no longer contains any interfaces, it is listed as inactive.

Dell#show vlan
                                 
                                 Codes: * - Default VLAN, G - GVRP VLANs
                                 NUM Status Q Ports
                                 * 1 Active   U Tengig 3/2
                                 2 Active   T Po1(So 0/0-1)
                                 T Tengig 3/0
                                 3 Active   T Po1(So 0/0-1)
                                 T Tengig 3/1
                                 4 Inactive
                                 Dell#conf
                                 Dell(conf)#int vlan 4
                                 Dell(conf-if-vlan)#untagged tengig 3/2
                                 Dell(conf-if-vlan)#show config
                                 !
                                 interface Vlan 4
                                 no ip address
                                 untagged Tengigabitethernet 3/2
                                 Dell(conf-if-vlan)#end
                                 Dell#show vlan
                                 
                                 Codes: * - Default VLAN, G - GVRP VLANs
                                 
                                 NUM Status Q Ports
                                 * 1 Inactive
                                 2 Active   T Po1(So 0/0-1)
                                 T Tengig 3/0
                                 3 Active   T Po1(So 0/0-1)
                                 T Tengig 3/1
                                 4 Active   U Tengig 3/2
                                 Dell#
                              

The only way to remove an interface from the Default VLAN is to place the interface in Default mode by using the no switchport command in INTERFACE mode.
