Our new Cisco ISR 4351s are deployed in a small closet with basic AC and not the best circulation,so  I wanted to make sure temperature was being trended in Cacti.

Finding the newer SNMP OIDs was a challenge but here they are:

$ snmpwalk -v 2c -c public isr.mydomain.com 1.3.6.1.2.1.47.1.1.1.1.2
iso.3.6.1.2.1.47.1.1.1.1.2.4 = STRING: "Temp: Temp 1"
iso.3.6.1.2.1.47.1.1.1.1.2.5 = STRING: "Temp: Temp 2"
iso.3.6.1.2.1.47.1.1.1.1.2.6 = STRING: "Temp: Temp 3"
iso.3.6.1.2.1.47.1.1.1.1.2.7001 = STRING: "Temp: Inlet 1"
iso.3.6.1.2.1.47.1.1.1.1.2.7002 = STRING: "Temp: Inlet 2"
iso.3.6.1.2.1.47.1.1.1.1.2.7003 = STRING: "Temp: Outlet 1"
iso.3.6.1.2.1.47.1.1.1.1.2.7004 = STRING: "Temp: Outlet 2"
iso.3.6.1.2.1.47.1.1.1.1.2.7005 = STRING: "Temp: CPU"

$ snmpwalk -v 2c -c public isr.mydomain.com 1.3.6.1.4.1.9.9.91.1.1.1.1.4
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.4 = INTEGER: 45
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.5 = INTEGER: 35
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.6 = INTEGER: 38
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.7001 = INTEGER: 33
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.7002 = INTEGER: 30
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.7003 = INTEGER: 37
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.7004 = INTEGER: 32
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.7005 = INTEGER: 36

The OIDs should be the same for the ASR 1000 series.  Since we’ll be replacing our 6504s likely with an ASR 1001-x pair this year, I’ll circle back and verify.
