allows packets in a data stream to arrive in the same order they
were sent. A trunk connection can be made with any other switch
that maintains host-to-host data streams over a single trunk port.
Switches that use a load-balancing scheme that sends the packets
of a host-to-host data stream over multiple trunk ports cannot have
a trunk connection with the DES-3326 switch.
Setting Up IP Interfaces
A Virtual Local Area Network (VLAN) is a network topology
configured according to a logical scheme rather than the physical
layout. VLANs can be used to combine any collection of LAN
segments into an autonomous user group that appears as a single
LAN. VLANs also logically segment the network into different
broadcast domains so that packets are forwarded only between
ports within the VLAN. Typically, a VLAN corresponds to a
particular subnet, although not necessarily.
VLANs can enhance performance by conserving bandwidth, and
improve security by limiting traffic to specific domains.
A VLAN is a collection of end nodes grouped by logic instead of
physical location. End nodes that frequently communicate with
each other are assigned to the same VLAN, regardless of where
they are physically on the network. Logically, a VLAN can be
equated to a broadcast domain, because broadcast packets are
forwarded to only members of the VLAN on which the broadcast
was initiated.

1. No matter what basis is used to uniquely identify
end nodes and assign these nodes VLAN
membership, packets cannot cross VLANs without
