have an aggregated connection with the DES-3250TG switch.

VLANs

A VLAN is a collection of end nodes grouped by logic rather
than physical location. End nodes that frequently communicate
with each other are assigned to the same VLAN, regardless of
where they are located physically on the network. Logically, a
VLAN can be equated to a broadcast domain, because
broadcast packets are forwarded only to members of the VLAN
on which the broadcast was initiated.
Notes About VLANs on the DES-3250TG
1. The DES-3250TG supports IEEE 802.1Q VLANs. The
port untagging function can be used to remove the
802.1Q tag
compatibility with devices that are tag-unaware (that is,
network devices that do not support IEEE 802.1Q
VLANs or tagging).
2. The switch's default is to assign all ports to a single
802.1Q VLAN named "default."
