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.
