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(ime-
out) timeout_ms] [-V(ersion)] [-h(elp)] [<dest dr_path|lid|guid>
[<startlid> [<endlid>]]]
DESCRIPTION
ibroute uses SMPs to display the forwarding tables (unicast (LinearFor-
wardingTable 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.
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 parame-
ters 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 possible.
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 resolution
ibroute 4 10 # dump lids starting from 10 (up to FDBTop)
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
