DoS trouble

Unanswered Question
Feb 19th, 2007

Hello All,

One of our 6509 switch was generating "icmpv6 multicast listener broadcast". I dont have any multicast or ipv6 configured on the device. The sup engine was choking during this trouble. I had to reboot the device to contain it.

Any one of you give me guidelines to avert this trouble.



I have this problem too.

It might be due to multicast enabled on some of your local machine which might cause unstable CPU.Try disabling PIM and see how it responeds.Refer URL'ip%20multicast%20rate-limit'%20%20on%206509&res=2&uid=&country=US&language=en&
