you must decide if you want the new port to be a member of the VLAN if it
isn't already. For example, if a node is on Port 1 in VLAN A, and you move the
node to Port 6, you may want to include Port 6 in VLAN A.
How the Data is Analyzed
The Network Performance Advisor analyzes historical traffic data for the time
period specified to determine which nodes on the network converse. These
nodes then are examined to determine if they have conversed frequently with
nodes on other segments. The Network Performance Advisor will recommend
moving a node to a different segment if: it is not on a desktop switch and the
move will reduce network traffic through networking devices that add latency
to each packet.
Add or Upgrade Equipment
The Add or Upgrade Equipment Report makes recommendations about
which segments can be divided into two or more segments to optimize
network performance. If the segment utilization is high, but segment division
will not reduce network utilization enough to improve network performance,
the report will recommend upgrading each segment to desktop switching or
a higher speed shared media. This will result in shorter response times for
software applications that are accessed across the network because each
node has its own dedicated network segment. The extraneous traffic that each
node hears in a shared-media environment is eliminated. Each node can use
the full capacity of the network.
If desktop switching is not feasible, an alternate option is to upgrade the
shared segment's speed.

Recommendation Details Section

The Recommendation Details section of the report supplies the supporting
information for the recommendations made by the Network Performance
Advisor. It include a textual explanation and the "before" and "after" graphical
representations of the affected network. The recommendations are in priority
order, starting with High Priority.
Dividing Segments into Workgroups
The Network Performance Advisor may determine that network performance
can be enhanced by dividing a segment into two or more groups of nodes. The
nodes in each group, often called a "workgroup", converse among themselves
most of the time. The workgroups are physically divided using a switch, bridge
or router.
A "before division" representation of the network traffic might look like the
following figure:
