Usage Guidelines
This command
enables ICMP size and fragment checking. This checking takes effect
for both IPv4 and IPv6 TCP packets. When enabled, the switch drops
ICMP packets if one of following condition is true:
-
Fragmented ICMP 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.)
