VENDSTAT(8) Open IB Diagnostics VENDSTAT(8)

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

A global config file is provided to set some of the common options for all tools. See supplied config file for details.

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
