--down,-d Print only nodes which have a port in the "Down" state.
--line,-l Print all information for each link on one line. Default is to print a header with the node
information and then a list for each port (useful for grep'ing output).
--additional,-p Print additional port settings (<LifeTime>,<HoqLife>,<VLStallCount>)
--switches-only Show only switches in output.
--cas-only Show only CAs in output.
PartialScanflags
The node to start a partial scan can be specified with the following addresses.
--port-guid,-G<port_guid> Specify a port_guid
-D,--Direct<dr_path> The address specified is a directed route
Examples:
-D "0" # self port
-D "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.)
Note: For switches results are printed for all ports not just switch port 0.
--switch,-S<port_guid> same as "-G". (provided only for backward compatibility)
How much of the scan to be printed can be controlled with the following.
--all,-a Print all nodes found in a partial fabric scan. Normally a partial fabric scan will return
only the node specified. This option will print the other nodes found as well.
--hops,-n<hops> Specify the number of hops away from a specified node to scan. This is useful to
expand a partial fabric scan beyond the node specified.
CacheFileflags--load-cache<filename> Load and use the cached ibnetdiscover data stored in the specified filename. May
be useful for outputting and learning about other fabrics or a previous state of a fabric.
--diff<filename> Load cached ibnetdiscover data and do a diff comparison to the current network or
another cache. A special diff output for ibnetdiscover output will be displayed showing differences
between the old and current fabric. By default, the following are compared for differences: switches,
channel adapters, routers, and port connections.
--diffcheck<key(s)> Specify what diff checks should be done in the --diff option above. Comma separate
multiple diff check key(s). The available diff checks are: port = port connections, state = port state,
lid = lids, nodedesc = node descriptions. Note that port, lid, and nodedesc are checked only for the
node types that are specified (e.g. switches-only, cas-only). If port is specified alongside lid or
nodedesc, remote port lids and node descriptions will also be compared.
--filterdownports<filename> Filter downports indicated in a ibnetdiscover cache. If a port was
previously indicated as down in the specified cache, and is still down, do not output it in the resulting
output. This option may be particularly useful for environments where switches are not fully populated,
thus much of the default iblinkinfo info is considered useless. See ibnetdiscover for information on
caching ibnetdiscover output.
PortSelectionflags-C,--Ca<ca_name> use the specified ca_name.
-P,--Port<ca_port> use the specified ca_port.
LocalportSelection
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.
Configurationflags--config,-z<config_file> Specify alternate config file.
Default: /etc/infiniband-diags/ibdiag.conf
--outstanding_smps,-o<val>
Specify the number of outstanding SMP's which should be issued during the scan
Default: 2
--node-name-map<node-name-map> Specify a node name map.
This file maps GUIDs to more user friendly names. See FILES section.
-t,--timeout<timeout_ms> override the default timeout for the solicited mads.
-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.
Debuggingflags-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.
