IBADDR - query InfiniBand address(es)SYNOPSISibaddr [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 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
-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.
--config, -z <config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf

EXAMPLESibaddr # 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
