ATM and VLAN Management Tools 1-25
The Topology View shows the layer 2 physical topology of large switched
infrastructures (networks with more than 500 Switches) in a single
hierarchy. For example, all the devices, such as ATM switches,
Fast-Ethernet Switches, and there corresponding edge devices, are
mapped.
The tree type Component View is hot linked to the Topology View and
allows for quick selection of infrastructure components that are
dynamically highlighted on the topology map. This feature allows you to
select an entry in the Component View, and view the highlighted
component in the Topology View using the Cross Reference icon.
For example, if you select a switch or an edge device from the ATMvLAN
Devices branch in the Component View, the selected switch is
highlighted in the Topology View. If you select a VLAN entry in the VLAN
branch, all the switches that belong to the VLAN are highlighted
The Component View has two windows for displaying the components.
The two windows allow for opening and viewing different branches at
the same time. For example, in the top window, a VLAN branch may be
opened displaying all the VLANs. In the bottom window, a specific VLAN
branch may be selected, and the segments within the VLAN displayed.
When performing VLAN moves, segments may be selected from one
window (top or source), and the target VLAN may be selected from the
other window (bottom).
Traffic pattern overlays are planned for the future in the Component View
as the Topology View will be hot linked to the Bandwidth Tool.
The topology map includes the following icons:
■ Zoom Out - This tool is used to magnify the topology map.
■ Zoom In - This tool is used to reduce the topology map.
■ Select Area - This tool is used to select an area of the topology map.
Use this tool by clicking on the icon and then defining an area (square)
on the topology map. The selected area is resized to fit the topology
map window. When used in conjunction with the Pan tool, you can
resize the selected area by resizing one of the rectangles handles using
MB1.
■ Pan - The tool opens up a display window that allows you to pan the
entire network.
