Not able to apply ipv4 and ipv6 access-rules

ip access-list NETBIOS-LLMNR

1010 deny tcp any any eq 139
1020 deny udp any any eq 5355
1030 permit every
exit
ipv6 access-list NETBIOS-LLMNR6
1000 deny udp any any range 137 138
1010 deny tcp any any eq 139
1020 deny udp any any eq 5355
1040 permit every

exit
interface vlan 22
ip access-group NETBIOS-LLMNR in 1
exit
interface vlan 24
ip access-group NETBIOS-LLMNR in 1
exit

when I try to add the ipv6 acl I get the following error message.

interface vlan 1
ipv6 traffic-filter NETBIOS-LLMNR6 in 1

Hi,

Which switch are you using and which OS version? Are those the only ACLs?
