Command Types Switch command.
Command Modes Normal or privileged.
Usage Guidelines General ping command guidelines are as follows:
• Press Ctrl-C to stop pinging.
• Continuous ping means that, unless you press Ctrl-C to stop pinging, packets are generated
continually and dispatched to the host.
• The actual packet size is 8 bytes larger than the size you specify because the switch adds
header information.
• Normal response—The normal response occurs in 1 to 10 seconds, depending on network traffic.
-s Causes ping to send one datagram per second, printing one line of output for every
response received.
