9 SYNOPSIS
10 ibroute [options] [<dest dr_path|lid|guid> [<startlid> [<endlid>]]]
11 DESCRIPTION
13 ibroute uses SMPs to display the forwarding tables (unicast (LinearFor‐
14 wardingTable or LFT) or multicast (MulticastForwardingTable or MFT))
15 for the specified switch LID and the optional lid (mlid) range. The
16 default range is all valid entries in the range 1...FDBTop.
17 OPTIONS
19 -a, --all
20 show all lids in range, even invalid entries
21 -n, --no_dests
23 do not try to resolve destinations
24 -M, --Multicast
26 show multicast forwarding tables In this case, the range parame‐
27 ters are specifying the mlid range.
28 Addressing Flags
30 -D, --Direct The address specified is a directed route
31 Examples:
33 [options] -D [options] "0" # self port
34 [options] -D [options] "0,1,2,1,4" # out via port 1, then 2, ...
35 (Note the second number in the path specified must match the port being
37 used. This can be specified using the port selection flag '-P' or the
38 port found through the automatic selection process.)
39 -G, --Guid The address specified is a Port GUID
41 -L, --Lid The address specified is a LID
43 -s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.
45 Port Selection flags
47 -C, --Ca <ca_name> use the specified ca_name.
48 -P, --Port <ca_port> use the specified ca_port.
50 Local port Selection
52 Multiple port/Multiple CA support: when no IB device or port is speci‐
53 fied (see the "local umad parameters" below), the libibumad library
54 selects the port to use by the following criteria:
55 1. the first port that is ACTIVE.
57 2. if not found, the first port that is UP (physical link up).
59 If a port and/or CA name is specified, the libibumad library
61 attempts to fulfill the user request, and will fail if it is not
62 possible.
63 For example:
65 ibaddr # use the first port (criteria #1 above)
67 ibaddr -C mthca1 # pick the best port from "mthca1" only.
68 ibaddr -P 2 # use the second (active/up) port from the first available IB device.
69 ibaddr -C mthca0 -P 2 # use the specified port only.
70 Debugging flags
72 -d raise the IB debugging level. May be used several times (-ddd
73 or -d -d -d).
74 -e show send and receive errors (timeouts and others)
76 -h, --help show the usage message
78 -v, --verbose
80 increase the application verbosity level. May be used several
81 times (-vv or -v -v -v)
82 -V, --version show the version info.
84 Configuration flags
86 -t, --timeout <timeout_ms> override the default timeout for the
87 solicited mads.
88 -y, --m_key <key>
90 use the specified M_key for requests. If non-numeric value (like
91 'x') is specified then a value will be prompted for.
92 --node-name-map <node-name-map> Specify a node name map.
94 This file maps GUIDs to more user friendly names. See FILES sec‐
95 tion.
96 --config, -z <config_file> Specify alternate config file.
98 Default: /etc/infiniband-diags/ibdiag.conf

101 CONFIG FILE
102 /etc/infiniband-diags/ibdiag.conf
103 A global config file is provided to set some of the common options for
105 all tools. See supplied config file for details.
106 NODE NAME MAP FILE FORMAT
108 The node name map is used to specify user friendly names for nodes in
109 the output. GUIDs are used to perform the lookup.
110 This functionality is provided by the opensm-libs package. See
112 opensm(8) for the file location for your installation.
