|Title||if_lancom: Never detect if if64-checks are disabled|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
The check if_lancom monitors network interfaces of LANCOM devices using 64-bit SNMP counters. Since there are devices with broken firmware which by mistake report that they support 64-bit counters, checkmk offers the rule "Hosts forced to use 'if' instead of 'if64'". This rule enforces the usage of the 32-bit SNMP interface check if over the 64-bit version.
Up to now, the check if_lancom did not fully apply this rule. I.e., depending on the device, even if this rule was activated, if_lancom might still have been discovered. With this werk, if_lancom is never discovered if "Hosts forced to use 'if' instead of 'if64'" is activated.
This change might be incompatible for users who activated the rule "Hosts forced to use 'if' instead of 'if64'". Currently discovered services will continue to work, however, upon rediscovery, if_lancom might be replaced by if. In such cases, users have to further restrict the hosts to which this rule is applied.
