IBPORTSTATE(8) Open IB Diagnostics IBPORTSTATE(8) NAME IBPORTSTATE - handle port (physical) state and link speed of an Infini- Band port 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 rel- ative 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 <op> 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) 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 indi- cated if port's 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 sup- port 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 '0x' or '0', respectively. If a non-numeric value (like 'x') is specified for the mkey, then ibportstate will prompt for a value. Addressing Flags -L, --Lid The address specified is a LID -G, --Guid The address specified is a Port GUID -D, --Direct The address specified is a directed route 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 '-P' or the port found through the automatic selection process.) -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 speci- fied (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. Configuration flags --config, -z <config_file> Specify alternate config file. Default: /etc/infiniband/infiniband-diags/ibdiag.conf -t, --timeout <timeout_ms> override the default timeout for the solicited mads. -y, --m_key <key> use the specified M_key for requests. If non-numeric value (like 'x') is specified then a value will be prompted for. Debugging flags -h, --help show the usage message -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) -K, --show_keys show security keys (mkey, smkey, etc.) associated with the request. -v, --verbose increase the application verbosity level. May be used several times (-vv or -v -v -v) -V, --version show the version info. FILES CONFIG FILE /etc/infiniband/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.
