       smpdump - dump InfiniBand subnet management attributes


       smpdump  [-s(ring)]  [-D(irect)]  [-C ca_name] [-P ca_port] [-t(imeout)
       timeout_ms] [-V(ersion)] [-h(elp)] <dlid|dr_path> <attr> [mod]


       smpdump is a general purpose SMP utility which gets SM attributes  from
       a specified SMA. The result is dumped in hex by default.


       attr   IBA attribute ID for SM attribute

       mod    IBA modifier for SM attribute


       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.


       Direct Routed Examples

       smpdump -D 0,1,2,3,5 16 # NODE DESC

       smpdump -D 0,1,2 0x15 2 # PORT INFO, port 2

       LID Routed Examples

       smpdump 3 0x15 2        # PORT INFO, lid 3 port 2

       smpdump 0xa0 0x11       # NODE INFO, lid 0xa0
