Catalyst 6500 Forwarding collapsed due to SSDP traffic

Hi all,

 

one of my customer had an issue related to multicast traffic.

 

couple of days ago, 

he received a SSDP-based DDoS. traffc was  around 300Mbps, the two devices which faces the internet  had a serious struggle and traffic was severely affected. there are were no CPU usage.per the customer  this was a TCAM issue related with the multicast nature of SSDP.
 

he is also planning to implement CoPP on that boxes,but as an advice they wanted to know if there are any other open issue on the current IOS they are running: (s72033_rp-IPSERVICESK9-M), Version 12.2(18)SXF7, RELEASE SOFTWARE (fc1)

 

if you could kindly share some knowledge I would greatly appreciate it.

with kind regards,

Lance
