Page 88 DES-3528 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual NOTE: In order to use VLAN segmentation in conjunction with port trunk groups, you can first set the port trunk group(s), and then you may configure VLAN settings. If you wish to change the port trunk grouping with VLANs already in place, you will not need to reconfigure the VLAN settings after changing the port trunk group settings.
Page 89: Double Vlans
DES-3528 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual Double VLANs Double or Q-in-Q VLANs allow network providers to expand their VLAN configurations to place customer VLANs within a larger inclusive VLAN, which adds a new layer to the VLAN configuration.
