# ibping(8)

ping an InfiniBand address

## 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.

- **-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.
