ping [-v ] [-i local_IP_address] [-l length] [-n count] [-t timeout] [-r rate] {-h server_IP_address}
| Name | Type | Description | Default |
|---|---|---|---|
| -v | Boolean | Be verbose, displaying information about each packet sent. | quiet |
| -n local_IP_address | Number | Controls the number of packets to be sent. | 10 |
| -i local_IP_address | Numeric IP or DNS name | The IP address RedBoot should use. | Value set by ip_address |
| -h server_IP_address | Numeric IP or DNS name | The IP address of the host to contact. | none |
| -l length | Number | The length of the ICMP data payload. | 64 |
| -r length | Number | How fast to deliver packets, i.e. time between successive sends. A value of 0 sends packets as quickly as possible. | 1000ms (1 second) |
| -t length | Number | How long to wait for the round-trip to complete, specified in milliseconds. | 1000ms (1 second) |
The ping command checks the connectivity of the local network by sending special (ICMP) packets to a specific host. These packets should be automatically returned by that host. The command will indicate how many of these round-trips were successfully completed.
Test connectivity to host 192.168.1.101.
