Troubleshooting Utilities
The Polycom RealPresence DMA system's Troubleshooting Utilities submenu includes several useful
network and system status commands, which you can run and view the output of in the system's familiar
graphical interface. Each command is run on each server in the cluster, and the results are displayed in a
separate panel for each server.
