Display Settings
Display Mode This button lets you choose between a non-editable
RingView mode and an editable Normal mode.
In RingView mode, the display is governed by the
RingView software and will show only entities that
have been determined to be part of the ring (i.e., no
Off-Page Reference icons will appear). Note also
that the display is locked. This means the FDDI
LAN model can NOT be destroyed, even if it was
created manually rather than by RingView. Also,
no annotations, manual repositionings of icons, or
other edits are permitted when this mode is in
effect. In Normal mode, the display may be edited
in the same manner as any regular SPECTRUM
Topology view. However, any icon position changes
or manual pipe connections you make in Normal
mode will not be preserved if you then switch back
to RingView mode. Annotations and background
color settings will remain in effect when you
switch modes, but the presence of any annotation
made in Normal mode will prevent the RingView
mode from being able to display the graphical
representation of the dual ring described below.w
Ring Display This button lets you choose between viewing the
FDDI LAN in Token Order (a single ring of nodes
positioned according to the order in which the
token is actually passed), or in a Ring of Trees
configuration, in which icons representing rooted
nodes are superimposed directly upon a graphical
representation of the dual counter-rotating ring,
and end nodes (entities connected to the “M” ports
of rooted nodes) are attached to the rooted node
icons via regular SPECTRUM connection pipes.
Figures 3-3 and 3-5 show an FDDI LAN as it
might appear with Token Order selected. Figures
3-4 and 3-6 show the Ring of Trees configuration.
Station Display This button lets you determine whether the icons
displayed in the FDDI LAN Topology view will
represent models of MAC Entities (SAS, DAC,
DAS as in Figures 3-3 and 3-4) or Physical
Devices (BdgCSIFDM, GnSNMPDev as in
Figures 3-5 and 3-6).
The default settings are RingView mode with MAC Entities in Token Order.
In order for any setting changes you make to take effect, you must first save
them by selecting the File menu’s “Save All Changes” option. Alternatively,
you can set your SpectroGRAPH so that you can press the right mouse button
to display the Commit Changes message box and then click on the OK button.
