You can check the status of a switch by checking its icon in the cluster list. If the switch is up, the icon is green; if it is down, the icon is red. (On the Catalyst 3524-PWR XL switch, the icon is yellow if the fan is broken or the switch is too hot.) The switch images on the Front Panel view show the status of switches and ports at the last polling interval.
You can check the status of ports by using the switch graphic. Click the mode button on the graphic to display the STAT, SPD, FDUP, and LINE PWR settings in sequence. The port LEDs change color to reflect the setting. Choose Help > Legend to learn the meanings of the colors on any switch in the cluster. (You cannot display switch utilization (UTIL) from the Front Panel view.)
Note: LINE PWR is shown only on Catalyst 3524-PWR XL switches, and only STAT and FDUP are shown on Catalyst 1900 and 2820 switches.
CMS updates status information in real-time by using data that the command switch receives from cluster members at regular polling intervals. You can change the polling interval by choosing CMS > Preferences and using the Preferences window.
