SYNOPSIS
ibportstate [options] <dest dr_path|lid|guid> <portnum> [<op>]
DESCRIPTION
ibportstate allows the port state and port physical state of an IB port to be queried (in addition to link width and speed being validated relative to the peer port when the port queried is a switch port), or a switch port to be disabled, enabled, or reset. It also allows the link speed/width enabled on any IB port to be adjusted.
OPTIONS
NDENT 0.0

<op> NDENT 7.0

Supported ops: enable, disable, reset, speed, espeed, fdr10, width, query, on, off, down, arm, active, vls, mtu, lid, smlid, lmc, mkey, mkeylease, mkeyprot (Default is query) NINDENT enable, disable, and reset are only allowed on switch ports (An error is indicated if attempted on CA or router ports) off change the port state to disable. on change the port state to enable(only when the current state is disable). speed and width are allowed on any port speed values are the legal values for PortInfo:LinkSpeedEnabled (An error is indicated if PortInfo:LinkSpeedSupported does not support this setting) espeed is allowed on any port supporting extended link speeds fdr10 is allowed on any port supporting fdr10 (An error is indicated if port\(aqs capability mask indicates extended link speeds are not supported or if PortInfo:LinkSpeedExtSupported does not support this setting) width values are legal values for PortInfo:LinkWidthEnabled (An error is indicated if PortInfo:LinkWidthSupported does not support this setting) (NOTE: Speed and width changes are not effected until the port goes through link renegotiation) query also validates port characteristics (link width, speed, espeed, and fdr10) based on the peer port. This checking is done when the port queried is a switch port as it relies on combined routing (an initial LID route with directed routing to the peer) which can only be done on a switch. This peer port validation feature of query op requires LID routing to be functioning in the subnet. mkey, mkeylease, and mkeyprot are only allowed on CAs, routers, or switch port 0 (An error is generated if attempted on external switch ports). Hexadecimal and octal mkeys may be specified by prepending the key with \(aq0x\(aq or \(aq0\(aq, respectively. If a non-numeric value (like \(aqx\(aq) is specified for the mkey, then ibportstate will prompt for a value. NINDENT

Addressing Flags
Define the common option -L
. -L, --Lid The address specified is a LID Define the common option -G
. -G, --Guid The address specified is a Port GUID Define the common option -D for Directed routes
. -D, --Direct The address specified is a directed route NDENT 0.0 NDENT 3.5
Examples:
 [options] -D [options] "0" # self port
 [options] -D [options] "0,1,2,1,4" # out via port 1, then 2, ...

 (Note the second number in the path specified must match the port being
 used. This can be specified using the port selection flag \(aq-P\(aq or the
 port found through the automatic selection process.)
NINDENT NINDENT Define the common option -s
. -s, --sm_port <smlid> use \(aqsmlid\(aq as the target lid for SA queries.
Port Selection flags
Define the common option -C
. -C, --Ca <ca_name> use the specified ca_name. Define the common option -P
. -P, --Port <ca_port> use the specified ca_port. Explanation of local port selection
.
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: NDENT 0.0 NDENT 3.5 NDENT 0.0
1. 3
the first port that is ACTIVE.
2. 3
if not found, the first port that is UP (physical link up). NINDENT 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: NDENT 0.0 NDENT 3.5
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.

Configuration flags
Define the common option -z
. --config, -z <config_file> Specify alternate config file. NDENT 0.0 NDENT 3.5 Default: /etc/infiniband-diags/ibdiag.conf NINDENT NINDENT Define the common option -t
. -t, --timeout <timeout_ms> override the default timeout for the solicited mads. Define the common option -y
. NDENT 0.0

-y, --m_key <key> use the specified M_key for requests. If non-numeric value (like \(aqx\(aq) is specified then a value will be prompted for. NINDENT

Debugging flags
Define the common option -h
. -h, --help show the usage message Define the common option -d
. NDENT 0.0

-d raise the IB debugging level. May be used several times (-ddd or -d -d -d). NINDENT Define the common option -e
. NDENT 0.0

-e show send and receive errors (timeouts and others) NINDENT Define the common option -K
. NDENT 0.0

-K, --show_keys show security keys (mkey, smkey, etc.) associated with the request. NINDENT Define the common option -v
. NDENT 0.0

-v, --verbose increase the application verbosity level. May be used several times (-vv or -v -v -v) NINDENT Define the common option -V
. -V, --version show the version info.
