UDP Packet attack - IPS detection

jpugliese · ‎02-19-2012

Hi,

I have been having logs for Access-lists configured on an interface on my 6509. Can anyone advise please if I am understanding it correct that IP10.61.64.202 is responsible for bursting attacks on udp port. Many thanks in advance for providing insight.
