Large ICMP packets in the rule

["Edwin Pua" <edwin1118 () hotmail com>]

Hi,
  Just want to clarify the ICMP packets in this rule. How large is the ICMP 
packets before alerting the snort? coz i have received 5 to 10 MISC Large 
ICMP Packet in just few minutes? Am i being flooded or attacked by DOS if it 
appears?

   Thanks for your info.

alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"MISC Large ICMP Packet"; 
dsize: >800; reference:arachnids,2
46; classtype:bad-unknown; sid:499; rev:1;)
