 Ports used by experimenters depend on the type of experiments run. For a list of current experimenter ports see the [wiki:KnownGENIPorts Known GENI Ports] page.
+
+=== Q. How can I tell and change the current switch configuration? ===
+
+SSH access to the switch should be enabled, allowing you to receive the FTOS (Force-ten OS) prompt.
+
+From there you can check current switch configuration from commands such as:
+
+{{{
+FTOS> show interfaces
+…
+
+FTOS>show openflow flows of-instance 1
+…
+
+FTOS> show clan
+…
+
+FTOS> show system
+…
+
+}}}
+
+Editing the system configuration requires entering into "enable" mode by typing the 'enable' command and providing the admin password.
+
+From there one can change configuration properties as documented in the Force10 switch documentation.

+=== Q: How can I monitor what load the compute and network resources are under? ===
+
+There are many commands that can be used at the switch (for network resources) or at the compute and control nodes (for memory, CPU and interfaces). In addition, OpenGENI racks fill a set of tables with recent measurements of network and CPU and disk performance in the monitoring mysql database:
