Ali,

IPv6 would be sending only multicast and no broadcasts. If any machine is configured for IPv6, they will send these multicast and the switch would mostly flood them.

Not sure if this will work but you can try denying the IPv6 packets on each port using an access-list

ipv6 access-list BLOCK deny ipv6 any any

interface x/y

ipv6 traffic-filter BLOCK in

The reason to put the access-list on the port is to block the traffic entering the switch itself.

If it is applied on a interface vlan, the traffic would anyway be flooded on the vlan the incoming port was part of.

BTW, did you try this out in any one port?
