vendstat(8)

Usage

vendstat {[options] <lid | guid>}

Overview

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.

-Y, --pkey-idx <idx>: P_Key table index (0-65535, default 0) used for the outgoing SA/GMP MADs. SMP (SMI directed-route/LID-routed) MADs always use P_Key index 0.

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
