IBADDR — query InfiniBand address(es)

Synopsis

ibaddr [options]

Description

Display the lid (and range) as well as the GID address of the port specified (by DR path, lid, or GUID) or the local port by default.

Note: this utility can be used as simple address resolver.

Options

--gid_show, -g
show gid address only
--lid_show, -l
show lid range only
--Lid_show, -L
show lid range (in decimal) only

Addressing Flags

-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.)

-G, --Guid The address specified is a Port GUID

-s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.

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.

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.

Configuration flags

-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.

-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

A global config file is provided to set some of the common options for all tools. See supplied config file for details.

Examples

ibaddr                  # local port\'s address
ibaddr 32               # show lid range and gid of lid 32
ibaddr -G 0x8f1040023   # same but using guid address
ibaddr -l 32            # show lid range only
ibaddr -L 32            # show decimal lid range only
ibaddr -g 32            # show gid address only
