show environment Command: Example

To view environmental monitor parameters for the system, use the show environment command in EXEC or administration EXEC mode.

Use the following command syntax:

show environment [options]

Type the show environment ? command to view the command options.

The following example shows a router’s temperature information:

RP/0/RSP0/CPU0:router# show environment			temperatures
R/S/I	Modules	Inlet	Hotspot
		Temperature	Temperature
		(deg C)	(deg C)
0/1/*
	host	28.1	35.7

	host	24.0	33.5
0/4/*
	host	26.7	35.0
0/6/*
	host	30.0	39.1

The following example shows a router’s LED status:

RP/0/RSP0/CPU0:router# show environment leds

	R/S/I	Modules	LED	Status
	0/RSP0/*
		host	Critical-Alarm	0
