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

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
