NAME
       ibstat - query basic status of InfiniBand device(s)

SYNOPSIS
       ibstat [-d(ebug)] [-l(ist_of_cas)] [-s(hort)] [-p(ort_list)] [-V(ersion)] [-h] <ca_name> [portnum]

DESCRIPTION
       ibstat  is  a binary which displays basic information obtained from the local IB driver. Output includes LID, SMLID, port state, link width
       active, and port physical state.

       It is similar to the ibstatus utility but implemented as a binary rather than a script. It has options to list CAs and/or  ports  and  dis-
       plays more information than ibstatus.

OPTIONS
       -l, --list_of_cas
	      list all IB devices

       -s, --short
	      short output

       -p, --port_list
	      show port list

       ca_name
	      InfiniBand device name

       portnum
	      port number of InfiniBand device

COMMON OPTIONS
       Most  OpenIB  diagnostics  take the following common flags. The exact list of supported flags per utility can be found in the usage message
       and can be shown using the util_name -h syntax.

       # 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      show the usage message

       -v      increase the application verbosity level.
	       May be used several times (-vv or -v -v -v)

       -V      show the version info.

       # Addressing flags

       -D      use directed path address arguments. The path
	       is a comma separated list of out ports.
	       Examples:
	       "0"	       # self port
	       "0,1,2,1,4"     # out via port 1, then 2, ...

       -G      use GUID address argument. In most cases, it is the Port GUID.
	       Example:
	       "0x08f1040023"

       -s <smlid>      use 'smlid' as the target lid for SM/SA queries.

       # Other common flags:

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

       -t <timeout_ms> override the default timeout for the solicited mads.

       Multiple CA/Multiple Port Support

       When no IB device or port is specified, the port to use is selected 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 user request is attempted to be fulfilled, and will fail if it is not possible.

EXAMPLES
       ibstat		 # display status of all ports on all IB devices

       ibstat -l	 # list all IB devices

       ibstat -p	 # show port guids

       ibstat mthca0 2	 # show status of port 2 of 'mthca0'
