Step8 Click Discover Network to begin Discovery.
When Discovery begins:
•The Discover Network button is grayed-out.
•The “Discovery In Progress” message is displayed at the bottom of the
Discovery Dialog.
•The “Discovery In Progress” message is displayed in the title bar of all SGM
client windows.
Discovery progresses in bursts. You might see a number of updates, followed by
a pause, followed by more updates. The information displayed in SGM windows
is not fully updated until Discovery is complete.
By default, Discovery times out after 600seconds (10 minutes). To change the
Discovery timeout, change the value of the DISCOVERY_TIMELIMIT entry in
the Server.properties file:
•If you installed SGM in the default directory, /opt, then the location of the
Server.properties file is /opt/CSCOsgm/properties/Server.properties.
•If you installed SGM in a different directory, then the Server.properties file is
located in that directory.
Because SGM is an asynchronous system, with the SGM server contacting clients
one at a time, and because clients might run at different speeds, the information
displayed by SGM clients during Discovery might not always be synchronized.
Step9 (Optional) To stop the Discovery process at any time, click Stop Discovery. For
example, if you click Discover Network, then you realize that you loaded a seed
node that you did not intend to load, you can click Stop Discovery to stop the
Discovery process.
Note If you stop the Discovery process, the information in the SGM database
is incomplete and unreliable. To generate a new, complete, and reliable
SGM database, you must run Discovery again, with Delete Existing
Data selected.
Step10 When the “Discovery In Progress” message disappears, Discovery is complete.
The Discovered Nodes section of the Discovery panel (Figure 3-5) lists all nodes
that were discovered by SGM. By default, this table is sorted by Status.
