Topology Mapping

Fabric Manager is built upon a topology representation of the fabric. Fabric Manager provides an
accurate view of multiple fabrics in a single window by displaying topology maps based on device
discovery information. You can modify the topology map icon layout with an easy-to-use, drag-and-drop
interface. The topology map visualizes device interconnections, highlights configuration information
such as zones, VSANs, and ISLs exceeding utilization thresholds. The topology map also provides a
visual context for launching command-line interface (CLI) sessions, configuring PortChannels, and
opening device managers.

Using the Topology Map

The Fabric Manager topology map can be customized to provide a view into the fabric that varies from
showing all switches, end devices, and links, to showing only the core switches with single bold lines
for any multiple links between switches. Use the icons along the left side of the topology map to control
these views or right-click anywhere in the topology map to access the map controls.
You can zoom in or out on the topology map to see an overview of the SAN or focus on an area of
importance. You can also open an overview window that shows the entire fabric. From this window, you
can right-click and draw a box around the area you want to view in the main topology map view.
Another way to limit the scope of the topology display is to select a fabric or VSAN from the Logical
Domains pane. The topology map displays only that fabric or VSAN.
Moving the mouse pointer over a link or switch provides a simple summary of that SAN component,
along with a status indication. Right-clicking on the component brings up a pop-up menu. You can view
the component in detail or access configuration or test features for that component.
Double-click a link to bring link status and configuration information to the information pane.
Double-click a switch to bring up Device Manager for that switch.

Saving a Customized Topology Map Layout

Changes made to the topology map can be saved so that the customized view is available any time you
open the Fabric Manager Client for that fabric.
To save the customized layout using Fabric Manager, follow these steps:
Step 1 Click File > Preferences to open the Fabric Manager preferences dialog box.
Step 2 Click the Map tab and check the Automatically Save Layout check box to save any changes to the
topology map (See
Cisco MDS 9000 Family Fabric Manager Configuration Guide
57-2
Figure 57-1).
