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
       /etc/infiniband-diags/ibdiag.conf

   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
