Configuring an ICMP echo operation
An ICMP echo operation measures the reachability of a destination device. It has the same function as
the ping command, but provides more output information. In addition, if multiple paths exist between the
source and destination devices, you can specify the next hop for the ICMP echo operation.
The ICMP echo operation is not supported in IPv6 networks. To test the reachability of an IPv6 address,
use the ping ipv6 command. For more information about the command, see System Maintenance
Command Reference.
