NAME

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

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

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
