|Title||Enforcing 32-bit interface checks is now done by disabling if64 SNMP section|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
This werk is only relevant for users who are currently using the ruleset "Hosts forced to use 'if' instead of 'if64'".
The rule "Include or exclude SNMP sections", which allows users to disable individual SNMP sections, will now replace the more specific rule for enforcing the usage of the 32- instead of the 64-bit interface check ("Hosts forced to use 'if' instead of 'if64'"). As of this werk, the latter rule is deprecated. To make Checkmk fall back to the 32-bit interface check, use "Include or exclude SNMP sections" to disable the corresponding 64-bit section (mostly if64).
This werk is incompatible only for users who actually activated the rule "Hosts forced to use 'if' instead of 'if64'". As described above, such users have to deactivate the section if64, otherwise, upon re-discovery, Checkmk will start to use the check plugin if64 instead of if. Note that besides the check plugin if64, the rule "Hosts forced to use 'if' instead of 'if64'" could also be used to make Checkmk use if instead of if_brocade and if_lancom. This option is still available, however, in these two particular cases, users will have to deactivate both the sections if_brocade/if_lancom and if64. If only the former were deactivated, Checkmk would fall back to if64.
