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

Files

Config File

/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
