--diffcheck <key(s)> Specify what diff checks should be done in the --diff option above. Comma separate multiple diff check key(s). The available diff checks are: sw = switches, ca = channel adapters, router = routers, port = port connections, lid = lids, nodedesc = node descriptions. Note that port, lid, and nodedesc are checked only for the node types that are specified (e.g. sw, ca, router). If port is specified alongside lid or nodedesc, remote port lids and node descriptions will also be compared.
