Figure 129. 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.
This limitation becomes relevant if you enable the port as a multi-purpose port (carrying single-tagged and double-tagged traffic).
When the LP ports are present in RPM 10 and 11, VLAN stacking is supported.
VLAN stacking is supported on C9010 ports but not on peGigE ports.
Configure VLAN Stacking
Configuring 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. Enabling VLAN-Stacking for a VLAN.
