CMK version:2.5.0p6

Will recive Label “cmk/device_type:switch”:
OMD[monitoring]:~$ snmpget -v2c -c public SWITCH-A 1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Aruba JL679A 6100 12G CL4 2SFP+ 139W Swch PL.10.13.1031

Will not recive Label “cmk/device_type:switch”:
OMD[monitoring]:~$ snmpget -v2c -c public SWITCH-B 1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: HPE ANW JL679A 6100 12G CL4 2SFP+ 139W Swch PL.10.16.1040

Hello Community,

I did a post in Troubleshooting in german earlier but I guess it is better posted in english language and I was able to test some more.

We have the rule “Interpretation of the device’s own temperature status” in place that forces all hosts with the label “cmk/device_type:switch” to ignore device’s own levels.

A Week ago we have updated a few Aruba JL679A 6100 switches from Firmware version 10.13 to 10.16. Now we had a few very hot days here and they startet signalling high temperatures in my dashboard.

What is new and unwanted by me: They decided to mark those services as critical again, obviously ignoring the rule I created long time ago.

I have now verified: Whenever I upgrade an Aruba switch from 10.13 to 10.16 it loses the label “cmk/device_type:switch”. Can anyone tell me how to fix this without manually adding the label to those Hosts?

Thanks for the detailed report including the sysDescr values — that was really helpful.

Root cause: The cmk/device_type label is derived from the SNMP sysDescr (.1.3.6.1.2.1.1.1.0). Checkmk simply looks for the word “Switch” (as a substring) within
that description. Your newer firmware reports the device type in an abbreviated form (e.g. “…Swch…”), so “Switch” is no longer found and the label drops off. So
this isn’t a misconfiguration on your side — it’s a limitation of the detection heuristic.

I’ve filed a ticket for this so that the Aruba detection also covers the abbreviated spelling.
Until that’s fixed, you can set the label manually: Setup → Hosts → Custom host labels (or directly on the host under “Labels”) and assign cmk/device_type:switch.
Then all views/rules that filter on this label will work as before again.
