Hello Luis,

see table 4-1 Hardware requirements in the following document


http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1053927


PFC, DFC, and CFC Requirements


The VSS supports any 67xx series switching module with CFC hardware


you can build a VSS the only limitation is that missing a WS-6708 or a WAS-6716 your VSS link can be made only of 10GE ports on the two supervisor.


if a supervisor fails the survirving supervisor may be not able to control both chassis.


if you add a WS-6708 with DFC3C on each chassis you can include 10GE ports of these linecards in the VSS bundle and so you can overcome the above limitation: if one supervisor fails the other one can control the other chassis.


Hope to help

Giuseppe
