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 (1/2/1) 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 (1/2/1). Because the Default VLAN no longer contains any interfaces, it is listed as inactive.

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.
Assigning an IP Address to a VLAN
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.
NOTE:
You cannot assign an IP address to the Default VLAN (VLAN 1). To assign another VLAN ID to the Default VLAN,
use the default vlan-id vlan-id command.
In Dell EMC Networking OS, you can place VLANs and other logical interfaces in Layer 3 mode to receive and send routed traffic. For
more information, refer to Bulk Configuration.
To assign an IP address, use the following command.
• Configure an IP address and mask on the interface.
INTERFACE mode
ip address ip-address mask [secondary]
• ip-address mask — Enter an address in dotted-decimal format (A.B.C.D) and the mask must be in slash format (/24).
• secondary — This is the interface’s backup IP address. You can configure up to eight secondary IP addresses.
