IPv6 has become a problem in our network. When a device that connects without IPv6 turned off (Apples or hp printers in particular) the VLAN gets pounded with IPv6 traffic and brings the VLAN to a stop. So, I thought that I might try to stop all v6 traffic on our 6509 core switches. I was wonder if the access-list below should work? And should it work on a 3750 with the ipservices image?
Also, is there another solution to stopping this?
Thanks, Pat.
access-list 101 permit ip any any
mac access-list extended IPV6
permit any any 0x86dd
vlan access-map BLOCK_IPV6 10
match mac-address IPV6
action drop
match ip address 101 20
action forward
vlan filter BLOCK_IPV6 vlan-list xx
Also, when I put this config on a 3750 in lab, I noticed that it asked me for a mask. What values should I configure?

That is not normal. you should find what exactly is happenign, as a cisco switch is supposed to handle whatever traffic type and volume without a problem.

How can I find out what the problem is? And where should I begin to look?

Also, if a Windows PC has IPV6 still on the network is not affected.
