       ibroute - query InfiniBand switch forwarding tables


       ibroute    [-d(ebug)]    [-a(ll)]   [-n(o_dests)]   [-v(erbose)]   [-D(irect)]   [-G(uid)]
       [-M(ulticast)] [-s smlid] [-C ca_name] [-P ca_port] [-t(imeout)  timeout_ms]  [-V(ersion)]
       [-h(elp)] [<dest dr_path|lid|guid> [<startlid> [<endlid>]]]


       ibroute uses SMPs to display the forwarding tables (unicast (LinearForwardingTable or LFT)
       or multicast (MulticastForwardingTable or MFT)) for  the  specified  switch  LID  and  the
       optional  lid  (mlid)  range.   The  default  range  is  all  valid  entries  in the range


       -a, --all
              show all lids in range, even invalid entries

       -n, --no_dests
              do not try to resolve destinations

       -M, --Multicast
              show multicast forwarding tables In this case, the range parameters are  specifying
              the mlid range.


       Most OpenIB diagnostics take the following common flags. The exact list of supported flags
       per utility can be found in the usage message and can be  shown  using  the  util_name  -h

       # Debugging flags

       -d      raise the IB debugging level.
               May be used several times (-ddd or -d -d -d).

       -e      show send and receive errors (timeouts and others)

       -h      show the usage message

       -v      increase the application verbosity level.
               May be used several times (-vv or -v -v -v)

       -V      show the version info.

       # Addressing flags

       -D      use directed path address arguments. The path
               is a comma separated list of out ports.
               "0"             # self port
               "0,1,2,1,4"     # out via port 1, then 2, ...

       -G      use GUID address argument. In most cases, it is the Port GUID.

       -s <smlid>      use 'smlid' as the target lid for SM/SA queries.

       # Other common flags:

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

       -t <timeout_ms> override the default timeout for the solicited mads.

       Multiple CA/Multiple Port Support

       When  no  IB  device  or  port  is specified, the port to use is selected by the following

       1. the first port that is ACTIVE.

       2. if not found, the first port that is UP (physical link up).

       If a port and/or CA name is specified, the user request is attempted to be fulfilled,  and
       will fail if it is not possible.


       Unicast examples

       ibroute 4       # dump all lids with valid out ports of switch with lid 4

       ibroute -a 4    # same, but dump all lids, even with invalid out ports

       ibroute -n 4    # simple dump format - no destination resolution

       ibroute 4 10    # dump lids starting from 10 (up to FDBTop)

       ibroute 4 0x10 0x20     # dump lid range

       ibroute -G 0x08f1040023 # resolve switch by GUID

       ibroute -D 0,1  # resolve switch by direct path

       Multicast examples

       ibroute -M 4    # dump all non empty mlids of switch with lid 4

       ibroute -M 4 0xc010 0xc020      # same, but with range

       ibroute -M -n 4 # simple dump format
