Moving Untagged Interfaces

To move untagged interfaces from the Default VLAN to another VLAN, use the following commands.

1. Access INTERFACE VLAN mode of the VLAN to which you want to assign the interface.

CONFIGURATION mode

interface vlan vlan-id

2. Configure an interface as untagged.

INTERFACE mode

untagged interface

This command is available only in VLAN interfaces.

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.
