FTOS#
When you remove a tagged interface from a VLAN (using the no tagged interface command), it remains tagged
only if it is a tagged interface in another VLAN. If the tagged interface is removed from the only VLAN to which it
belongs, the interface is placed in the Default VLAN as an untagged interface.
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.
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.
