ibroute - query InfiniBand switch forwarding tables
ibroute [options] [<dest dr_path|lid|guid> [<startlid> [<endlid>]]]
ibroute uses SMPs to display the forwarding tables (unicast (LinearForwardingTable or LFT) or multicast (MulticastForwardingTable or MFT)) for the specified switch LID and the optional lid (mlid) range. The default range is all valid entries in the range 1...FDBTop.
-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
-L, --Lid The address specified is a LID
-s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.
-C, --Ca <ca_name> use the specified ca_name.
-P, --Port <ca_port> use the specified ca_port.
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:
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.
-h, --help show the usage message
-V, --version show the version info.
-t, --timeout <timeout_ms> override the default timeout for the solicited mads.
--node-name-map <node-name-map> Specify a node name map.
--config, -z <config_file> Specify alternate 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.
The node name map is used to specify user friendly names for nodes in the output. GUIDs are used to perform the lookup.
This functionality is provided by the opensm-libs package. See opensm(8) for the file location for your installation.
