ibaddr8
Query infiniband address(es)
Usage
ibaddr [options]
Overview
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.
-
-Y, --pkey-idx <idx> -
P_Key table index (0-65535, default 0) used for the outgoing SA/GMP MADs. SMP (SMI directed-route/LID-routed) MADs always use P_Key index 0.
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

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
