# vendstat

## 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:
              /ssd11/FOSS/rdma-core/build/etc/infiniband-diags/ibdiag.conf

## 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
