[raindrop18]

I have router 3640, and switches 3750 and 2950 switches. do these switches have heat sensor? if not is there any other way I can monitor the temprature. thanks in advance for any suggestions.

3640 doesn't have one.

2950 doesn't have one either.

3750 have.  Use the command "sh env al".

thanks, so then why the 3750 show only "Temp is ok". not showing the exact temp like on C or F just say ok. like 6500 you can get the exact temp.  anyway to know the exact temp or that's all you can get.

That's because the original design concept of the 6500 was for data centre.  And in a data centre you really have to focus on the ambient temperature.  That is why the 6500 has a thermal detection function.

Hi

Actually you can get the temperature in degrees on the 3750.

show env temp status

You can also set different treasholds for at what temperature the switch should warn.

fx

syst env temp threshold yellow

I am not 100% shure but I do not think you can set condition red though.

Good luck
