NAME
ibroute - query InfiniBand switch forwarding tables
SYNOPSIS
ibroute [-d(ebug)] [-a(ll)] [-n(o_dests)] [-v(erbose)]
[-D(irect)] [-G(uid)] [-M(ulticast)] [-s smlid] [-C ca_name]
[-P ca_port] [-t(imeout) timeout_ms] [-V(ersion)] [-h(elp)]
[<dest dr_path|lid|guid> [<startlid> [<endlid>]]]
DESCRIPTION
ibroute uses SMPs to display the forwarding tables (unicast
(LinearForwardingTable or LFT) or multicast (MulticastFor-
wardingTable 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.
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.
COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The
exact list of supported flags per utility can be found in
the usage message and can be shown using the util_name -h
syntax.
# 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 show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the version info.
# Addressing flags

-D use directed path address arguments. The path
is a comma separated list of out ports.
Examples:
"0" # self port
"0,1,2,1,4" # out via port 1, then 2, ...
-G use GUID address argument. In most cases, it is the
Port GUID.
Example:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SM/SA
queries.
# Other common flags:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-t <timeout_ms> override the default timeout for the
solicited mads.
Multiple CA/Multiple Port Support
When no IB device or port is specified, the port to use is
selected 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 user request is
attempted to be fulfilled, and will fail if it is not possi-
ble.
EXAMPLES
Unicast examples
ibroute 4 # dump all lids with valid out ports of
switch with lid 4
ibroute -a 4 # same, but dump all lids, even with invalid
out ports
ibroute -n 4 # simple dump format - no destination reso-
lution
ibroute 4 10 # dump lids starting from 10 (up to FDBTop)
OpenIB Last change: July 25, 2006 2
OpenIB Diagnostics IBROUTE(1m)
ibroute 4 0x10 0x20 # dump lid range
ibroute -G 0x08f1040023 # resolve switch by GUID
ibroute -D 0,1 # resolve switch by direct path
Multicast examples
ibroute -M 4 # dump all non empty mlids of switch with
lid 4
ibroute -M 4 0xc010 0xc020 # same, but with range
ibroute -M -n 4 # simple dump format
