Description

This InfiniBand software command uses vendor supplied management datagrams to validate connectivity between InfiniBand nodes. The command is a client-server, in that a remote node is configured as a server, while a local node performs as a client. Output is similar to the Internet Protocol ping command.

The command is first run locally on the server. The command is then run again locally on the client, pointing to the LID of the server. The ping repeats every second, until the Ctrl-C key combination exits on the server.
