NAME

       IBROUTE -

query InfiniBand switch forwarding tables

   SYNOPSIS
       ibroute [options] [<dest dr_path|lid|guid> [<startlid> [<endlid>]]]

   DESCRIPTION
       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
       1...FDBTop.

   OPTIONS
       -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.

   Addressing Flags
       -D, --Direct     The address specified is a directed route

       Examples:
          [options] -D [options] "0"          # self port
          [options] -D [options] "0,1,2,1,4"  # out via port 1, then 2, ...

          (Note the second number in the path specified must match the port being
          used.  This can be specified using the port selection flag '-P' or the
          port found through the automatic selection process.)

       -G, --Guid     The address specified is a Port GUID

       -L, --Lid   The address specified is a LID

       -s, --sm_port <smlid>     use 'smlid' as the target lid for SA queries.

   Port Selection flags
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

   Local port Selection
       Multiple  port/Multiple CA support: when no IB device or port is specified (see the "local
       umad parameters" below), the libibumad library selects the port to use  by  the  following
       criteria:

          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 libibumad library attempts to fulfill the
          user request, and will fail if it is not possible.

          For example:

          ibaddr                 # use the first port (criteria #1 above)
          ibaddr -C mthca1       # pick the best port from "mthca1" only.
          ibaddr -P 2            # use the second (active/up) port from the first available IB device.
          ibaddr -C mthca0 -P 2  # use the specified port only.

   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, --help      show the usage message

       -v, --verbose

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

       -V, --version     show the version info.

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

       -y, --m_key <key>

              use  the specified M_key for requests. If non-numeric value (like 'x') is specified
              then a value will be prompted for.

       --config, -z  <config_file> Specify alternate config file.

          Default: /etc/infiniband-diags/ibdiag.conf

   CONFIG FILE

   EXAMPLES
       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
