untagged interface INTERFACE Configure an interface as untagged.
This command is available only in VLAN
interfaces.
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. Figure 78 illustrates the steps and commands to move an untagged interface from the
Default VLAN to another VLAN.

Figure 78 Example of Moving an Untagged Interface to Another VLAN
The only way to remove an interface from the Default VLAN is to place the interface in Default mode by
entering the no switchport command in the INTERFACE mode.
assign an IP address to a VLAN
Use the show vlan command to determine
interface status. 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). Since the
Default VLAN no longer contains any interfaces,
it is listed as inactive.
VLANs are a Layer 2 feature. For two physical interfaces on different VLANs to communicate, you must
assign an IP address to the VLANs to route traffic between the two interfaces.
The shutdown command in INTERFACE mode does not affect Layer 2 traffic on the interface; the
shutdown command only prevents Layer 3 traffic from traversing over the interface.
