LOOP
LOOP
Sends ICMP ECHO packets to hosts to determine whether they are active. Same
as the PING command.
Format
LOOP [ host ]
[ /ADDRESS=xx.xx.xx.xx ]
[ /ALL ]
[ /FULL ]
[ /NUMBER_PACKETS=n ]
[ /PACKET_SIZE=n ]
[ /PATTERN="hexadecimal-string" ]
[ /[NO]ROUTE ]
[ /WAIT=n ]
Parameters
host
Optional. Default: None.
Specifies the host to which the test packets are sent. Omitting the host parameter
and the /ADDRESS qualifier tests the TCP/IP Services software on the local node,
as defined by the system logical TCPIP$INET_HOST.
Qualifiers
/ADDRESS=xx.xx.xx.xx
Optional.
Specifies the IP address of the host to which the test packets are sent.
/ALL
Optional. Default: Not all requests.
Displays all ICMP ECHO_REQUESTs, even if not in direct response to this
operation.
/FULL
Optional.
Numeric output only. No attempt is made to look up symbolic names for host
addresses. This occurs only when displaying ICMP packets other than ECHO_
RESPONSE.
/NUMBER_PACKETS=n
Optional. Default: 4 packets
Specifies the number of packets to send. If you specify 0, packets are sent
continuously until you terminate the LOOP command with Ctrl/C.
/PACKET_SIZE=n
Optional. Default: 64 bytes.
Specifies the size of the ICMP ECHO_REQUEST.
