8.13 Ping: Permitted length of ICMP packets
Pings with a packet size of more than 1000 bytes are evaluated as an attack and
filtered by the CP. This response is deliberate and serves to increase robustness in
an industrial environment.
A ping only serves to check reachability. Support of extremely long ICMP packets
is not therefore a necessity.
