Figure 116. VLAN Stacking in a Service Provider Network
Important Points to Remember
Interfaces that are members of the Default VLAN and are configured as VLAN-Stack access or trunk ports do not switch
untagged traffic. To switch traffic, add these interfaces to a non-default VLAN-Stack-enabled VLAN.
Dell EMC Networking cautions against using the same MAC address on different customer VLANs, on the same VLAN-Stack
VLAN.
This limitation becomes relevant if you enable the port as a multi-purpose port (carrying single-tagged and double-tagged
traffic).
Configure VLAN Stacking
Configuring VLAN-Stacking is a three-step process.
1. Creating Access and Trunk Ports
2. Assign access and trunk ports to a VLAN (Creating Access and Trunk Ports).
3. Enabling VLAN-Stacking for a VLAN.
