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

Files

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
