ping

Use the ping command to send ICMP echo-request packets to another node on the network.

ping [-s] host [packet_size] [packet_count]

Syntax Description

-s	(Optional) Keyword to cause ping to send one datagram per second, printing one line of output for every response received.
host	IP address or IP alias of the host.
packet_size	(Optional) Number of bytes in a packet, from 56 to 1472 bytes.
packet_count	(Optional) Number of packets to send.

Defaults

The default packet_size is 56 bytes.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

Press Ctrl-C to stop pinging.

Following are sample results of the ping command:

•Normal response—The normal response occurs in 1 to 10 seconds, depending on network traffic.

•Destination does not respond—If the host does not respond, a "no answer from host" appears in 10 seconds.

•Destination unreachable—The gateway for this destination indicates that the destination is unreachable.

•Network or host unreachable—The switch found no corresponding entry in the route table.

The actual packet size will be 8 bytes larger than the size you specify because the switch adds header information.

The ping command returns output only when a response is received.

Examples

This example shows how to ping a host with IP alias elvis a single time:

Console> ping elvis

elvis is alive

Console> 

This example shows how to ping a host with IP alias elvis once per second until you press Ctrl-C to stop pinging:

Console> ping -s elvis

ping elvis: 56 data bytes

64 bytes from elvis: icmp_seq=0. time=11 ms

64 bytes from elvis: icmp_seq=1. time=8 ms

64 bytes from elvis: icmp_seq=2. time=8 ms

64 bytes from elvis: icmp_seq=3. time=7 ms

64 bytes from elvis: icmp_seq=4. time=11 ms

64 bytes from elvis: icmp_seq=5. time=7 ms

64 bytes from elvis: icmp_seq=6. time=7 ms

In the match string, the most recent command to begin with the specified string is executed again.

If the string contains white space, you must use quotation marks.

This command is usually aliased to the letter "r."
