This read-only CmDiagCableCondType object reports the diagnosed condition (such as open, short, or normal) of copper cable Pair 1 on an Ethernet Network Port after a diagnostic test. It matters because a single bad conductor pair, rather than a fully broken cable, is a common and otherwise hard-to-isolate cause of intermittent Gigabit link issues. For example, if a port only links at 100 Mbps instead of 1 Gbps, an admin would check cmEthernetNetPortDiagnosePair1Cond to see if that specific pair reports a fault preventing full Gigabit operation.
