vendstat uses vendor specific MADs to access beyond the IB spec vendor specific functionality. Currently, there is support only for Mellanox InfiniSwitch-III (IS3).
-N show IS3 general information.
-w show IS3 port xmit wait counters.
-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
-G use GUID address argument. In most cases, it is the Port GUID. Example: "0x08f1040023"
-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.
vendstat -N 6 # read IS3 general information
vendstat -w 6 # read IS3 port xmit wait counters
