VLAN Stacking
Overview
With the VLAN-Stacking feature (also called Stackable VLANs and QinQ), you can
“stack” VLANs into one tunnel and switch them through the network transparently.
This feature is supported by FTOS on all Dell Force10 platforms as indicated by the
characters that appear under each of the command headings:
e E-Series, c
C-Series,
s S-Series, , or .
Commands
The commands included are:
dei enable
dei honor
dei mark
member
show interface dei-honor
show interface dei-mark
stack-unit stack-group
vlan-stack access
vlan-stack compatible
vlan-stack dot1p-mapping
vlan-stack protocol-type
vlan-stack trunk
For information on basic VLAN commands, refer to Virtual LAN (VLAN)
Commands in the chapter Layer 2.
Important Points to Remember
If Spanning Tree Protocol (STP) is not enabled across the Stackable VLAN
network, STP BPDUs from the customers networks are tunneled across the
Stackable VLAN network.
