Re: 6509 and VSS ??

Redundant sups per chassis in VSS mode are newly supported in 12.2(33)SXI4.

Virtual Switching System (VSS) Quad-Supervisor Uplink Forwarding

Cisco IOS Software Release 12.2(33)SXI4 introduces support for
dual-supervisors in each of the active and standby VSS chassis,
together forming a quad-supervisor VSS system. These secondary
supervisors can also be used to forward traffic on the uplink ports
thereby enabling all four supervisors in a VSS system to actively
forward traffic under normal conditions. Furthermore, the additional
supervisors can act as standby supervisors within each chassis to
provide resilient network connectivity to single-homed devices and
maximum bandwidth availability to both upstream and downstream
connected devices.
