ibping8
Ping an infiniband address
Usage
ibping {[options]
<dest
lid | guid>}
Overview
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.
-
-Y, --pkey-idx <idx> -
P_Key table index (0-65535, default 0) used for the outgoing SA/GMP MADs. SMP (SMI directed-route/LID-routed) MADs always use P_Key index 0.
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.
