An S series switch fails to ping the remote device using ping packets carrying the source IP address. Why the ping succeeds after the source IP address is changed

For S series switches (except the S1700), the possible reason why the ping succeeds after the source IP address is changed is that the remote device does not have a return route to send response packets. If the ping succeeds after you change the source IP address or do not specify any source IP address in the ping command, you need to check whether the remote device has a return route.
