Hi Chuck, yes you have to configure a specific SDM template (and reboot the device) in order to use IPv6.
I have already activated this, otherwise the 3750 does not recognize any IPv6 commands. 3750#show sdm prefer The current template is "desktop IPv4 and IPv6 routing" template. Thanks for your time.
