+title: Correlation of the state of carp interfaces on genuscreen devices
+agents: snmp
+catalog: hw/network/genua
+license: GPL
+distribution: check_mk
+description:
+ This check monitors if the two carp interfaces found on genuscreen devices
+ have the same carp state. If not, the check is critical.
+
+ The check is known to run with genuscreen version 3.0 and supports genuas regular
+ enterprise id 3717 as well as the id 3137 which was introduced in a bug in some
+ versions of genuscreen.
+
+perfdata:
+ None
+
+inventory:
+ The inventory process checks if the device has a system description OIDs
(.1.3.6.1.2.1.1.2.0)
+ and if the name of this OID contains "genuscreen" (case insensitive).
+ If this is true the system is inventorized.
