There are duplicate interface items found by if64 and interfaces. There was only if64 items until version CRE 2.3.0p29.
I found the problem in the werk 17786. After renaming ~/lib/python3/cmk/plugins/collection/agent_based/if32_with_alias.py the problem disappears.

Can confirm this as a 2.3.0p30 bug in CEE as well, I don’t have the time to fix it myself right now but raised a ticket with checkmk GmbH :slight_smile:

FYI this will be fixed in 2.3.0p31 Werk #17881: if64/interfaces: Duplicate service description
