NAME

IBPING - ping an InfiniBand address

SYNOPSIS

ibping [options] <dest lid | guid>

DESCRIPTION

ibping uses vendor mads to validate connectivity between IB nodes. On exit, (IP) ping like output is show. ibping is run as client/server. Default is to run as client. Note also that a default ping server is implemented within the kernel.

OPTIONS

-c, --count stop after count packets

-f, --flood flood destination: send packets back to back without delay

-o, --oui use specified OUI number to multiplex vendor mads

-S, --Server start in server mode (do not return)

Addressing Flags

-L, --Lid The address specified is a LID

-G, --Guid The address specified is a Port GUID

-s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.

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:

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 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.

Configuration flags

--config, -z <config_file> Specify alternate config file. Default: /etc/infiniband-diags/ibdiag.conf

-t, --timeout <timeout_ms> override the default timeout for the solicited mads.

Debugging flags

-h, --help show the usage message

-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)
-v, --verbose: increase the application verbosity level. May be used several times (-vv or -v -v -v)
-V, --version show the version info.
