Parameters
host (OPTIONAL) Enter the host name of the devices to which you are testing

datagram size Enter the ICMP datagram size. The range is from 36 to 15360 bytes. The default is
100.
timeout Enter the interval to wait for an echo reply before timing out. The range is from 0
to 3600 seconds. The default is 2 seconds.
source Enter the IPv4 or IPv6 source ip address or the source interface. For IPv6

format.
● For a Port Channel interface, enter the keyword port-channel then a
number: The range is from 1 to 128.
