Dual Supervisor VSS on Single Chassis

Unanswered Question
Sep 1st, 2010

I just recently got to know that Cisco has released the SW version in which dual CPU's are supported on single Chassis. Total we have four CPU's with VSS enabled. Have anybody implemented it? Any issues? Any concerns?

I have this problem too.

SXI4/SXI4a support dual supervisor engine on a VSS chassis.

Haven't tried it yet.

As Leo noted, it is supported in SHI4 and 4a, but since this IOS version is very new, I have not been able to find a good document explaining how the fail over actually works.
