C6506E/SUP2T dual supervisor in VSS mode

[Xiang Hong Angela YAN]

the VSS configuration guide for the 15.n(SY) version, all have following lines:
"VSS mode does not support supervisor engine redundancy within a chassis"

Is there OS version available to support redundant supervisor engine within each chassis(two C6506-SUP2T chassis in VSS mode

there are two c6506e chassis with 2x SUP2T in each chassis

As long as VSS is configured as quad sup, it should work fine. From the same link you posted:

VSS Quad-Sup SSO (VS4O)

Release 15.1(1)SY1 and later releases support the VSS Quad-Sup SSO (VS4O) feature.
