IBPRINTRT(8)                OpenIB Diagnostics               IBPRINTRT(8)

NAME top

       ibprintrt.pl - print either only the router specified or a list of
       routers from the ibnetdiscover output

SYNOPSIS top

       ibprintrt.pl [-R -l -C <ca_name> -P <ca_port>]
       [<rt_guid|node_name>]

DESCRIPTION top

       Faster than greping/viewing with an editor the output of
       ibnetdiscover, ibprintrt.pl will parse out and print either the
       router information for the specified IB router or a list of all IB
       routers in the subnet.

       Finally, ibprintrt.pl will also reuse the cached ibnetdiscover
       output from some of the other diag tools which makes it a bit
       faster than running ibnetdiscover from scratch.

OPTIONS top

       -l     List the Rts (simply a wrapper for ibrouters).

       -R     Recalculate the ibnetdiscover information, ie do not use
              the cached information.  This option is slower but should
              be used if the diag tools have not been used for some time
              or if there are other reasons to believe that the fabric
              has changed.

       -C <ca_name>    use the specified ca_name for the search.

       -P <ca_port>    use the specified ca_port for the search.
