When configuring network interfaces to be discovered by alias or description (rule "Network interface and switch port discovery"), there was a chance of a mismatch between the discovered service item and the interface checked by the service.
This happened if the alias or description of one interface matched the index of another interface. For example, if the interface discovery is configured to discover interfaces by alias, then the service "Interface 5" is supposed to check the interface with the alias "5". Instead, it checked the interface with the index 5.
Compatibility Hint
To apply the fix, you need to remove the interface services and rediscover them. If you do not remove and rediscover them, the fix will not be applied and you might still have mismatched services.
