Figure 102. 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 Networking cautions against using the same MAC address on different customer VLANs, on the same VLAN-Stack VLAN.
• You cannot ping across the trunk port link if one or both of the systems is an S3100 series.
• 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.
