Uplink LAG

The tagged VLAN membership of the uplink LAG is automatically
configured based on the VLAN configuration of all server-facing ports (ports 1
to 32).
The untagged VLAN used for the uplink LAG is always the default VLAN.

Server-Facing LAGs

The tagged VLAN membership of a server-facing LAG is automatically
configured based on the server-facing ports that are members of the LAG.
The untagged VLAN of a server-facing LAG is configured based on the
untagged VLAN to which the lowest numbered server-facing port in the LAG
belongs.
Tip: Dell Force10 recommends that you configure the same VLAN
membership on all LAG member ports.

Stacking Mode

When you configure an Aggregator to operate in stacking mode
("Configuring and Bringing Up a Stack" on page 31), VLANs are reconfigured
as follows:
•
If an Aggregator port belonged to all 4094 VLANs in standalone mode
(default), all VLAN membership is removed and the port is assigned only
to default VLAN 1. You must configure additional VLAN membership as
necessary.
•
If you had manually configured an Aggregator port to belong to one or
more VLANs (non-default) in standalone mode, the VLAN configuration
is retained in stacking mode only on the master switch.
When you reconfigure an Aggregator from stacking to standalone mode:
•
Aggregator ports that you manually configured for VLAN membership in
stacking mode retain their VLAN configuration in standalone mode.
•
To restore the default auto-VLAN mode of operation (in which all ports are
members of all 4094 VLANs) on a port, enter the auto vlan command; for
example:
FTOS(conf)# interface tengigabitethernet 0/2
FTOS(conf-if-te-0/2)# auto vlan
