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 S4048–ON.

This limitation becomes relevant if you enable the port as a multi-purpose port (carrying single-tagged and double-tagged traffic).

Configuring VLAN-Stacking is a three-step process.
