Figure 40-1. VLAN Stacking in a Service Provider Network

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, these interfaces must be added to a non-default

VLAN-Stack-enabled VLAN.

Dell Force10 cautions against using the same MAC address on different customer VLANs, on the

same VLAN-Stack VLAN.

You can ping across a trunk port only if both systems on the link are an E-Series. You cannot ping

across the link if one or both of the systems is a C-Series or S-Series.

This limitation becomes relevant if you enable the port as a multi-purpose port (carrying single-tagged

and double-tagged traffic).

Configure VLAN Stacking

Configuring VLAN-Stacking is a three-step process:

1. Create access and trunk ports. See page 821.

2. Assign access and trunk ports to a VLAN. See page 821.

3. Make the VLAN VLAN-stacking capable.
