Table 32 - iblinkinfo Flags and Options
Flags Description
-S <port_guid> -G <port_guid> --port-guid start partial scan at the port specified by <port_guid> (hex
format)
-D <direct_route> start partial scan atthe port specified by the direct route
path.
-l Print all information for each link on one line. Defaultis to
print aheaderwith 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-R (This option is obsolete and does nothing)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> Load and use the cached ibnetdiscover data stored in the
speci-fied filename. May be useful for outputting and
learning about other fabrics or a previous state of a fabric.
Cannot be used if user specifies a direct route path. See
ibnetdiscover for information on caching ibnetdiscover
output.
--diff <filename> Load 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 comparedfor differences: port connections and
port state. See ibnetdiscover for information on caching
ibnetdiscover output.
--diffcheck <key(s)> Specify what diff checks should be done in the--diffoption
above. Comma separate multiple diff check key(s). The
available diff checks are:port = port connections,state =
port state, lid = lids, nodedesc = node descriptions. If port
is specified alongside lid or nodedesc, remote port lids and
node descriptions will also be compared.
