       ibstat - query basic status of InfiniBand device(s)


       ibstat    [-d(ebug)]    [-l(ist_of_cas)]    [-s(hort)]   [-p(ort_list)]
       [-V(ersion)] [-h] <ca_name> [portnum]


       ibstat is a binary which displays basic information obtained  from  the
       local  IB  driver.  Output  includes LID, SMLID, port state, link width
       active, and port physical state.

       It is similar to the ibstatus  utility  but  implemented  as  a  binary
       rather  than  a  script.  It  has  options to list CAs and/or ports and
       displays more information than ibstatus.


       -l, --list_of_cas
              list all IB devices

       -s, --short
              short output

       -p, --port_list
              show port list

              InfiniBand device name

              port number of InfiniBand device


       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 syntax.

       # 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 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 user request is attempted to
       be fulfilled, and will fail if it is not possible.


       ibstat            # display status of all ports on all IB devices

       ibstat -l         # list all IB devices

       ibstat -p         # show port guids

       ibstat mthca0 2   # show status of port 2 of ’mthca0’
