This command sends ICMP echo request packets to another node on the network.

Syntax

ping host [size size] [count count]

•host - IP address or IP alias of the host.

•size - Number of bytes in a packet. (Range: 32-512, default: 32)

The actual packet size will be eight bytes larger than the size specified

because the switch adds header information.
