How the changes will be applied
When you click the wizard's Finish button, the changes that you made in
this wizard stage will be applied to the selected switch ports as follows:
If the untagged combo box selection is left unchanged, the VLAN on
which the selected ports are transmitting untagged packets will not be
modified. If the combo-box selection is left as <mixed>, then the
VLANs on which the selected ports are transmitting untagged packets
will not be modified.
If the untagged combo box selection is changed to a particular VLAN,
e.g. Accounts (ID=3), then the selected ports will be configured such
that they now transmit untagged packets on this VLAN. If some ports
were previously transmitting untagged packets on a different VLAN,
these ports will be removed from this VLAN. If some ports were
already transmitting untagged packets on the selected VLAN, these
ports will not be modified.
If the untagged combo-box selection is changed to <none>, then the
selected ports will be removed from any VLAN(s) on which they were
previously transmitting untagged packets. However this will not be
done if, as a result, the ports will not be members of any VLANs –

3Com Network Director will check that all of the selected ports will be
