dump_fts - Man Page
dump InfiniBand forwarding tables
Synopsis
dump_fts [options] [<startlid> [<endlid>]]
Description
dump_fts is similar to ibroute but dumps tables for every switch found in an ibnetdiscover scan of the subnet.
The dump file format is compatible with loading into OpenSM using the -R file -U /path/to/dump-file syntax.
Options
- -a, --all
show all lids in range, even invalid entries
- -n, --no_dests
do not try to resolve destinations
- -M, --Multicast
show multicast forwarding tables In this case, the range parameters are specifying the mlid range.
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:
- the first port that is ACTIVE.
- 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.
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, --version show the version info.
Configuration flags
-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.
--node-name-map <node-name-map> Specify a node name map.
This file maps GUIDs to more user friendly names. See Files section.
--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.
Node Name Map File Format
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.
Generically:
# comment <guid> "<name>"
