Parameters
-c count: Specifies the number of ICMP echo requests to send, in the range of 1 to 2147483647. The
default is 5.
-s size: Specifies the length (in bytes) of each ICMP echo request, in the range of 20 to 8100. The
default is 56.
ip-address: Specifies the IPv4 address of the destination in dotted decimal notation.
Usage guidelines
When you execute the ping command, the device sends ICMP echo requests to the destination. You
can press Ctrl+C to abort the ping operation.
Examples
# Check the connectivity to the destination 1.2.1.1.
<boot> ping 1.2.1.1
PING 1.2.1.1 (1.2.1.1): 56 data bytes
56 bytes from 1.2.1.1: seq=0 ttl=128 time=2.243 ms
56 bytes from 1.2.1.1: seq=1 ttl=128 time=0.717 ms
56 bytes from 1.2.1.1: seq=2 ttl=128 time=0.891 ms
56 bytes from 1.2.1.1: seq=3 ttl=128 time=0.745 ms
56 bytes from 1.2.1.1: seq=4 ttl=128 time=0.911 ms
