In the 3560's, there is the dual-ipv4-and-ipv6 template not available in the
3550's:
++++++++++++++++++++++
Switch(config)#sdm prefer ?
access multicast and qos/acl bias, drop unicast
extended-match Using extended match for unicast routing
routing unicast bias, drop qos/acl
vlan vlan bias, drop routing
<cr>
Switch(config)#
++++++++++++++++++++++
Even with the routing template, no ipv6 support available:
++++++++++++++++++++++
Switch#
Switch#sh sdm prefer | inc current
The current template is the routing extended-match template.
Switch#
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#ipv6 ?
% Unrecognized command
Switch(config)#ipv6 unicast-routing
^
% Invalid input detected at '^' marker.
Switch(config)#
++++++++++++++++++++++
All this has to do with fall-back bridging. I remember that we could
fallback bridge IPv6 in the 3550's. Now it seems we can't:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/1
2.2_44_se/configuration/guide/swfallbk.html#wp1038531
So i was assuming that this was due to the fact that the 3550's now support
ipv6. But i can't find a way to enable it.

Change your SDM? Even on a 3560, none of the commands show up until you do
so!

How did you enabled ipv6 on your 3550 ? I have mine with 12.2(46)SE and i
don't see trace of ipv6 on it:
+++++++++++++++++++++++++++
Switch#sh ver | inc IOS
Cisco IOS Software, C3550 Software (C3550-IPSERVICESK9-M), Version
12.2(46)SE, RELEASE SOFTWARE (fc2) Switch# Switch# Switch#conf t Enter
configuration commands, one per line. End with CNTL/Z.
Switch(config)#ipv6 unicast-routing
^
% Invalid input detected at '^' marker.
Switch(config)#
+++++++++++++++++++++++++++
Anyone has any official document saying that the 3550's now support ipv6 ?
Thanks.
