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 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.

Configuring Native VLANs

Traditionally, ports can be either untagged for membership to one VLAN or tagged for membership to multiple VLANs.
You must connect an untagged port to a VLAN-unaware station (one that does not understand VLAN tags), and you must connect
a tagged port to a VLAN-aware station (one that generates and understands VLAN tags).
Native VLAN support breaks this barrier so that you can connect a port to both VLAN-aware and VLAN-unaware stations. Such
ports are referred to as hybrid ports. Physical and port-channel interfaces may be hybrid ports.
Native VLAN is useful in deployments where a Layer 2 port can receive both tagged and untagged traffic on the same physical port.
The classic example is connecting a voice-over-IP (VOIP) phone and a PC to the same port of the switch. The VOIP phone is
configured to generate tagged packets (with VLAN = VOICE VLAN) and the attached PC generates untagged packets.
NOTE: When a hybrid port is untagged in a VLAN but it receives tagged traffic, all traffic is accepted.
NOTE: You cannot configure an existing switchport or port channel interface for Native VLAN. Interfaces must have no
other Layer 2 or Layer 3 configurations when using the portmode hybrid command or a message similar to this
displays: % Error: Port is in Layer-2 mode Gi 5/6.
To configure a port so that it can be a member of an untagged and tagged VLANs, use the following commands.
1. Remove any Layer 2 or Layer 3 configurations from the interface.
INTERFACE mode
2. Configure the interface for Hybrid mode.
