NAME

       vendstat - query InfiniBand vendor specific functions

SYNOPSIS

       vendstat [options] <lid|guid>

DESCRIPTION

       vendstat  uses  vendor  specific  MADs  to  access  beyond  the  IB  spec  vendor specific
       functionality. Currently,  there  is  support  for  Mellanox  InfiniSwitch-III  (IS3)  and
       InfiniSwitch-IV (IS4).

OPTIONS

       -N     show IS3 or IS4 general information.

       -w     show IS3 port xmit wait counters.

       -i     show IS4 counter group info.

       -c <num,num>
              configure IS4 counter groups.

              Configure  IS4  counter groups 0 and 1. Such configuration is not persistent across
              IS4 reboot.  First number is for counter group 0 and second is for counter group 1.

              Group 0 counter config values:

       ::
                 0 - PortXmitDataSL0-7 1 - PortXmitDataSL8-15 2 - PortRcvDataSL0-7

              Group 1 counter config values:

       ::     1 - PortXmitDataSL8-15 2 - PortRcvDataSL0-7 8 - PortRcvDataSL8-15

       -R, --Read <addr,mask>
              Read configuration space record at addr

       -W, --Write <addr,val,mask>
              Write configuration space record at addr

   Addressing Flags
       -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.

       --config, -z  <config_file> Specify alternate config file.
          Default: /etc/infiniband-diags/ibdiag.conf

   CONFIG FILE

EXAMPLES

       ::     vendstat  -N  6            #  read  IS3  or  IS4  general information vendstat -w 6
              # read IS3 port xmit wait counters vendstat -i 6  12         #  read  IS4  port  12
              counter  group  info vendstat -c 0,1 6 12    # configure IS4 port 12 counter groups
              for PortXmitDataSL vendstat -c 2,8 6 12    # configure IS4 port 12  counter  groups
              for PortRcvDataSL
