I'm having trouble finding the actual temperature point where a C2821 router will send out the trap for temperature. So far, I know the operating temperatures are from 0C to 40C. But at which point does it send the trap?
The thresholds will differ depending on the IOS, platform, and component in question. The
show environment table command will display the temperature thresholds. When a threshold is crossed, a SNMP trap will be sent, if the router is configured to do so.
Here is a sample output:
R1#show environment table Sample Point LowShut LowCrit LowWarn HighWarn HighCrit HighShut I/O Cont Inlet 40C/104F 50C/122F 75C/167F I/O Cont Outlet 43C/109F 53C/127F 58C/136F NPE Inlet 75C/167F 75C/167F 75C/167F NPE Outlet 50C/122F 60C/140F 65C/149F +3.45 V +2.42 +3.18 +3.72 +4.48 +5.15 V +3.62 +4.80 +5.49 +6.72 +12.15 V +8.54 +11.29 +13.00 +15.85 -11.95 V -7.04 -9.52 -14.38 -16.38

environment command can be found in the Cisco IOS Configuration Fundamentals
