SNMP temperature not shown for Cisco 3850 switches

CMK version: 2.2.0p6
OS version: AlmaLinux 9.2

Querying a Cisco 3850 with SNMP yields no temperature data. A similar Cisco 9300 series switch does provide temperature data. There is a generic temperature rule in check_mk but applying it to the 3850 doesn’t change anything. I’ve also seen this page:

but I don’t know how it applies to my situation.

Also, FYI, these switches work under librenms and show temperature data.

Sorry, it was my fault for having an old IOS version. Please disregard the question.
