Figure 104. VLAN Stacking in a Service Provider Network
Important Points to Remember
Interfaces that are members of the Default VLAN and are congured as VLAN-Stack access or trunk ports do not switch untagged
trac. To switch trac, add these interfaces to a non-default VLAN-Stack-enabled VLAN.
Dell Networking cautions against using the same MAC address on dierent customer VLANs, on the same VLAN-Stack VLAN.
Congure VLAN Stacking
Conguring 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 Enable VLAN-Stacking for a VLAN.
