Install Guide

The following example shows the steps to add a tagged interface (in this case, port channel 1) to VLAN 4. To view the
interface’s status. Interface (po 1) is tagged and in VLAN 2 and 3, use the show vlan command. In a port-based VLAN, use
the tagged command to add the interface to another VLAN. The show vlan command output displays the interface’s (po 1)
changed status.
Except for hybrid ports, only a tagged interface can be a member of multiple VLANs. You can assign hybrid ports to two VLANs
if the port is untagged in one VLAN and tagged in all others.
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 (1/2) 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 (1/2). 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.
