Command Syntax Command Mode Purpose
vlan untagged {vlan-id | vlan-range} INTERFACE Add the interface as an untagged member of one or more
VLANs, where:
vlan-id species an untagged VLAN number. Range: 2-4094
vlan-range species a range of untagged VLANs. Separate
VLAN IDs with a comma; specify a VLAN range with a dash;
for example, vlan tagged 3,5-7.
When you delete a VLAN (using the no vlan vlan-id command), any interfaces assigned to the VLAN are assigned to the
default VLAN as untagged interfaces.
If you congure additional VLAN membership and save it to the startup conguration, the new VLAN conguration is activated
following a system reboot.
Dell Networking OS Behavior:When two or more server-facing ports with VLAN membership are congured in a LAG based on the
NIC teaming conguration in connected servers learned via LACP, the resulting LAG is a tagged member of all the congured VLANs
and an untagged member of the VLAN to which the port with the lowest port ID belongs. For example, if port 0/3 is an untagged
member of VLAN 2 and port 0/4 is an untagged member of VLAN 3, the resulting LAG consisting of the two ports is an untagged
member of VLAN 2 and a tagged member of VLAN 3.
Displaying VLAN Membership
To view the congured VLANs, enter the show vlan command in EXEC privilege mode:
Dell#show vlan
Codes: * - Default VLAN, G - GVRP VLANs, R - Remote Port Mirroring VLANs, P - Primary, C -
Community, I - Isolated

G - GVRP tagged, M - Vlan-stack, H - VSN tagged
i - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT tagged

NOTE: A VLAN is active only if the VLAN contains interfaces and those interfaces are operationally up. In the above
example, VLAN 1 is inactive because it does not contain any interfaces. The other VLANs listed contain enabled
interfaces and are active. In a VLAN, the
shutdown command stops Layer 3 (routed) trac only. Layer 2 trac
continues to pass through the VLAN. If the VLAN is not a routed VLAN (that is, congured with an IP address), the
shutdown command has no aect on VLAN trac.
Adding an Interface to a Tagged VLAN
The following example shows you how to add a tagged interface (Tel/7) to a VLAN (VLAN 2).
Enter the vlan tagged command to add interface Te 1/7 to VLAN 2, which is as shown below. Enter the show vlan command
to verify that interface Te 1/7 is a tagged member of VLAN 2..
Dell(conf-if-te-1/7)# vlan tagged 2
Dell(conf-if-te-1/7)# exit
Dell(conf)# exit
Dell# show vlan id 2
