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.
