do partial scans and limit its output to parts of a fabric.

Table 31 - iblinkinfo Flags and Options
Flags Description
-S <port_guid> -G <port_guid> --port-guid Starts partial scan at the port specified by <port_guid>
(hex format)
-D <direct_route> Starts partial scan at the port specified by the direct route
path.
-l Prints all information for each link on one line. Default is to
print a header with the node information and then a list for
each port (useful for grep´ing output).
-d Prints only nodes which have a port in the "Down" state.
-p Prints additional port settings (<Life-
Time>,<HoqLife>,<VLStall-Count>)
-C <ca_name> Uses the specified ca_name for the search.
-P <ca_port> Uses the specified ca_port for the search.
-R (This option is obsolete and does nothing)
--load-cache <filename> Loads and use the cached ibnetdiscover data stored in the
specified filename. May be useful for outputting and learn-
ing about other fabrics or a previous state of a fabric. Can-
not be used if user specifies a direct route path. See
ibnetdiscover for information on caching ibnetdiscover out-
put.
--diff <filename> Loads cached ibnetdiscover data and do a diff comparison
to the
current network or another cache. A special diff output
for iblinkinfo output will be displayed showing differences
between the old and current fabric links. Be default, the fol-
lowing are compared for differences: port connections and
port state. See ibnetdiscover for information on caching
ibnetdiscover output.
