Starts a loop test between the loopback applications on the
    specified source and destination nodes. The node keyword
    specifies the node from which the loop messages are sent. If
    you omit this keyword, the test is performed from the node on
    which you issue the loop command. The name or address argument
    specifies the node whose loop mirror is used to reflect the
    messages back to the originator. Specify either the name or
    address (but not both).

 o  address tower-set

    Number of the destination for loopback messages, in the form
    of a protocol tower. Specify either this argument or the name
    argument.

 o  count integer

    Default: 1             Value: 0-4294967295

    Number of loop messages to be sent to the loop mirror. The test
    is complete when this number of loop messages has been reflected
    back by the loop mirror.

 o  format hex-string

    Default: 55            Value: 00-FF

    Content of the data field of a loop message. Enter a pair of
    hexadecimal digits. Each octet in the data field of a loop
    message has this value.

 o  length integer

    Default: 40            Value: 0-65534

    Length, in octets, of the data field in each loop message.

 o  name full-name

    DNS name of the node to which loopback messages are sent. Specify
    either this argument or the address argument, but not both.
