     70=== Q. How can I tell and change the current switch configuration? ===
     71
     72SSH access to the switch should be enabled, allowing you to receive the FTOS (Force-ten OS) prompt.
     73
     74From there you can check current switch configuration from commands such as:
     75
     76{{{
     77FTOS> show interfaces
     78
     79
     80FTOS>show openflow flows of-instance 1
     81
     82
     83FTOS> show clan
     84
     85
     86FTOS> show system
     87
     88
     89}}}
     90
     91Editing the system configuration requires entering into "enable" mode by typing the 'enable' command and providing the admin password.
     92
     93From there one can change configuration properties as documented in the Force10 switch documentation.

     177=== Q: How can I monitor what load the compute and network resources are under? ===
     178
     179There 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:
