ICMP packets if one of following condition is true:
-
Fragmented
ICMP packets for IPv4 packets.
-
IPv4 ICMP pings packets with payload size greater than the
maximum IPv4 ICMP-allowed size. (The maximum allowed size is configurable.)
-
IPv6 ICMP ping packets with payload size > the maximum IPv6
ICMP-allowed size. (The maximum allowed size is configurable.)
