6 ibroute - query InfiniBand switch forwarding tables
7
9 ibroute [options] [<dest dr_path|lid|guid> [<startlid> [<endlid>]]]
10
12 ibroute uses SMPs to display the forwarding tables (unicast (LinearFor‐
13 wardingTable or LFT) or multicast (MulticastForwardingTable or MFT))
14 for the specified switch LID and the optional lid (mlid) range. The
15 default range is all valid entries in the range 1...FDBTop.
16
18 -a, --all
19 show all lids in range, even invalid entries
20 -n, --no_dests
22 do not try to resolve destinations
23 -M, --Multicast
25 show multicast forwarding tables In this case, the range parame‐
26 ters are specifying the mlid range.
27 Addressing Flags
29 -D, --Direct The address specified is a directed route
30 Examples:
32 [options] -D [options] "0" # self port
33 [options] -D [options] "0,1,2,1,4" # out via port 1, then 2, ...
34 (Note the second number in the path specified must match the port being
36 used. This can be specified using the port selection flag '-P' or the
37 port found through the automatic selection process.)
38 -G, --Guid The address specified is a Port GUID
40 -L, --Lid The address specified is a LID
42 -s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.
44 Port Selection flags
46 -C, --Ca <ca_name> use the specified ca_name.
47 -P, --Port <ca_port> use the specified ca_port.
49 Local port Selection
51 Multiple port/Multiple CA support: when no IB device or port is speci‐
52 fied (see the "local umad parameters" below), the libibumad library
53 selects the port to use by the following criteria:
54 1. the first port that is ACTIVE.
56 2. if not found, the first port that is UP (physical link up).
58 If a port and/or CA name is specified, the libibumad library
60 attempts to fulfill the user request, and will fail if it is not
61 possible.
62 For example:
64 ibaddr # use the first port (criteria #1 above)
66 ibaddr -C mthca1 # pick the best port from "mthca1" only.
67 ibaddr -P 2 # use the second (active/up) port from the first available IB device.
68 ibaddr -C mthca0 -P 2 # use the specified port only.
69 Debugging flags
71 -d raise the IB debugging level. May be used several times (-ddd
72 or -d -d -d).
73 -e show send and receive errors (timeouts and others)
75 -h, --help show the usage message
77 -v, --verbose
79 increase the application verbosity level. May be used several
80 times (-vv or -v -v -v)
81 -V, --version show the version info.
83 Configuration flags
85 -t, --timeout <timeout_ms> override the default timeout for the
86 solicited mads.
87 -y, --m_key <key>
89 use the specified M_key for requests. If non-numeric value (like
90 'x') is specified then a value will be prompted for.
91 --node-name-map <node-name-map> Specify a node name map.
93 This file maps GUIDs to more user friendly names. See FILES sec‐
94 tion.
95 --config, -z <config_file> Specify alternate config file.
97 Default: /etc/infiniband-diags/ibdiag.conf
98
100 CONFIG FILE
101 /etc/infiniband-diags/ibdiag.conf
102 A global config file is provided to set some of the common options for
104 all tools. See supplied config file for details.
105 NODE NAME MAP FILE FORMAT
107 The node name map is used to specify user friendly names for nodes in
108 the output. GUIDs are used to perform the lookup.
109 This functionality is provided by the opensm-libs package. See
111 opensm(8) for the file location for your installation.
