Important Points To Remember; Configure Vlan Stacking - Dell S4048–ON Configuration Manual

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).
