12-5. Environmental Monitoring

NOTE

Temperature monitoring commands are currently available only on the Catalyst 6000 and 4000 switch families.

Table 12-6 lists some switch commands that you can use to display helpful information about environmental monitoring.

Table 12-6. Switch Commands to Display Environmental Monitoring Information

Display Function	Switch OS	Command
Module temperatures	COS	show environment temperature
	IOS	(exec) show environment temperature

The output from the show environment temperature command lists the temperatures measured at the intake and exhaust of each module, with the warning and critical alarm temperatures in parentheses. To operate normally, a switch temperature should not exceed the levels shown within the parentheses.

"Device 1" and "Device 2" temperatures refer to additional sensors within the modules. "VTT" modules are located on the chassis backplane.
