[c-nsp] c3560 IPv6 and ACL

Hi

We are slowly moving toward IPv6 implementation in production, so I 
came to ACLs. I would want to have some protection for our servers,
so I went to configure IPv6 ACL, which is based on our IPv4 ACL.
Problem is, that it looks like I can't make host based ACL entries
on c3560. If I try to add line for SMTP server I get following:

interface FastEthernet0/1
  no switchport
  ipv6 address xxxx:xxxx:0:3::1/64
  ipv6 enable
  ipv6 traffic-filter fw-ipv6 out

test(config)#ipv6 access-list fw-ipv6
test(config-ipv6-acl)#permit tcp any host xxxx:xxxx:0:3::2 eq 25
% Host address xxxx:xxxx:0:3::2 can not be supported
% ACE can not be added
% Failed to add access list

If I try to do same thing on c12008, it works without problems.

Any idea how to solve this problem?

PS: This c3560 is running Adv. IP services 12.2.40.SE IOS, in case if
this matters. And preffered SDM template is "desktop IPv4 and IPv6 routing".

Have fun,
