Configuring Double Vlan Tagging - Dell Networking N4000 Series Configuration Manual

Configuring Double VLAN Tagging

Beginning in Privileged EXEC mode, use the following commands to
configure an interface to send and accept frames with double VLAN tagging.
DVLAN uplink interfaces must be configured for tagging (trunk mode) for
double tags to be observed on frames egressing the interface. DVLAN uplink
interfaces should be configured to accept tagged frames for the DVLAN or
outer VLAN. Ensure that the native VLAN on the uplink port is set to the
DVLAN ID. MAC address learning on DVLAN enabled ports occurs on the
DVLAN uplink port's native VLAN.
Enabling DVLAN tunneling configures all ports in the system as access ports
except those configured as uplink ports. Access ports must be configured with
the uplink ports native VLAN as their PVID.
