This read-only object reports whether a port is connected to a host (other(1), the default at initialization) or has been identified as an interconnect port (interconnect(2)) after the NMM saw hello messages arriving on it. An admin checks this to distinguish end-station-facing ports from ports that link to another NMM or bridge, which matters for how node address collection is applied by default. A value of interconnect(2) tells the admin that port links to another switch or bridge rather than to an end host, based on observed hello traffic.
