Sorry for the flood, but to avoid false information, I checked in my lab
and ipv6 commands are not available with IP Services either, unless using a
Dual SDM Template.

Switch#sh ver | in ^License|^Cisco
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version
License Level: ipservices
License Type: Permanent
Switch#sh sdm pref | in current
 The current template is "desktop default" template.
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int vl 1
% Unrecognized command

As mentioned in the Configuration Guide, it is required to change to Dual
SDM template with the 'sdm prefer dual-ipv4-and-ipv6' then reload the
switch in order to have ipv6 commands available.
