Figure 112. VLAN Stacking in a Service Provider Network
Important Points to Remember
• Interfaces that are members of the Default VLAN and are congured as VLAN-Stack access or trunk ports do not switch
untagged trac. To switch trac, add these interfaces to a non-default VLAN-Stack-enabled VLAN.
• Dell Networking cautions against using the same MAC address on dierent customer VLANs, on the same VLAN-Stack VLAN.
Congure VLAN Stacking
Conguring 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.
Related Conguration Tasks
