+
  A comma separated list of network interface names that should be pinged instead of the interface represented by the nodename/hostname.
  The following name resolution convention is assumed:  an interface is reachable by the hostname <nodename>-<interface>.  For example,
  the ib2 interface on node3 has a hostname of node3-ib2.
- 
+
  If more than one interface is specified, each interface will be combined with the nodenames as described above and will be pinged in turn.
