The settings in the window are explained below, with their defaults. If you change the default settings, you can restore them by clicking Set Defaults.

Settings are saved in permanent storage on the command switch, so they remain in effect in from session to session.

Changing the Network Polling Interval

The network polling interval determines how often CMS polls the command switch to determine the status of the cluster and the existence of new members. This information is used to refresh the Topology view, the Front Panel view, and many of the configuration windows.

Default: 5 minutes.

To change the network polling interval, use the Network polling interval spin buttons.

Changing the LED Polling Interval

The LED polling interval determines how often CMS polls the LEDs (light emitting diodes) for the devices in the cluster. With each interval, CMS displays interface and RPS information with LED colors in the Front Panel view. You can select the kind of information that the color representslink status, port speed, duplex state, or power stateby clicking the button on the left of the view.

Default: 5 minutes.

Go to Color Code - Ports to see what each of the LED colors means.

Changing the Link and Switch Graph Polling Interval

The graph polling interval determines how often CMS queries the command switch to obtain switch and link utilization data throughout the cluster. This information is used to update the link and bandwidth graphs.

Default: 20 seconds.

To change the link and device graph polling interval, use the Graph polling interval spin buttons.

Selecting Which Windows Appear at Startup

You can ask to see both the Front Panel view and the Topology view when CMS is accessed on the command switch. You can also ask for just one view or neither.

Defaults: Show Front Panel view at startup, checked; Show Topology view at startup, unchecked.

Showing Ports That Are Administratively Shut Down

In the Front Panel view, ports that you shut down appear the same as ports that the software shuts down. To make the appearance of the former distinctive, you can ask to see them in brown.

Default: Show administratively shut down ports in brown, unchecked.
