SNMP OID question for switch temperature

[ajwhite0]

Hello,

Another here:

If I run an SNMPwalk on a 2960 I can get it's temperature via:

sudo snmpwalk -v2c -c public 192.168.1.1 .1.3.6.1.4.1.9.9.13.1.3.1.

Result =

iso.3.6.1.4.1.9.9.13.1.3.1.3.1012 = Gauge32: 43

If I run it against a 3850 stack of 4 switches I get 3 temperatures for each, what are these?

iso.3.6.1.4.1.9.9.13.1.3.1.3.1013 = Gauge32: 40
iso.3.6.1.4.1.9.9.13.1.3.1.3.1014 = Gauge32: 43
iso.3.6.1.4.1.9.9.13.1.3.1.3.2012 = Gauge32: 32
iso.3.6.1.4.1.9.9.13.1.3.1.3.2013 = Gauge32: 41
iso.3.6.1.4.1.9.9.13.1.3.1.3.2014 = Gauge32: 43
iso.3.6.1.4.1.9.9.13.1.3.1.3.3012 = Gauge32: 31
iso.3.6.1.4.1.9.9.13.1.3.1.3.3013 = Gauge32: 40
iso.3.6.1.4.1.9.9.13.1.3.1.3.3014 = Gauge32: 43
iso.3.6.1.4.1.9.9.13.1.3.1.3.4012 = Gauge32: 34
iso.3.6.1.4.1.9.9.13.1.3.1.3.4013 = Gauge32: 39
iso.3.6.1.4.1.9.9.13.1.3.1.3.4014 = Gauge32: 42

            - Presumably there are 3 sensors per device,

If you walk 1.3.6.1.4.1.9.9.13.1.3.1 it will give you more info. The values should show as switch # - temp sensor 0,1,2 

0 is the inlet temp

1 is the outlet temp

2 is the hotspot (CPU) temp
