Example of Verifying a Port-Based VLAN
To view the congured VLANs, use the show vlan command in EXEC Privilege mode.
Dell#show vlan

Assigning Interfaces to a VLAN
You can only assign interfaces in Layer 2 mode to a VLAN using the tagged and untagged commands. To place an interface in Layer 2
mode, use the switchport command.
You can further designate these Layer 2 interfaces as tagged or untagged. For more information, refer to the Interfaces chapter and
Conguring Layer 2 (Data Link) Mode. When you place an interface in Layer 2 mode by the switchport command, the interface is
automatically designated untagged and placed in the Default VLAN.
To view which interfaces are tagged or untagged and to which VLAN they belong, use the show vlan command. The following example
shows that six VLANs are congured, and two interfaces are assigned to VLAN 2. The Q column in the
show vlan command example
notes whether the interface is tagged (T) or untagged (U). For more information about this command, refer to the Layer 2 chapter of the
Dell Networking OS Command Reference Guide.
To tag frames leaving an interface in Layer 2 mode, assign that interface to a port-based VLAN to tag it with that VLAN ID. To tag
interfaces, 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 Enable an interface to include the IEEE 802.1Q tag header.
INTERFACE mode
tagged interface
Add an Interface to Another VLAN
To view just the interfaces that are in Layer 2 mode, use the show interfaces switchport command in EXEC Privilege mode or
EXEC mode.
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.
