Can you put 4 x 6807's in VSS mode as one cluster?

[Ric Hernandez]

We have 4 6807's that we're going to use to replace 2 6509's.  Each 6807 has a SUP6T engine.  Can we put all 4 switches in VSS mode in a single domain?  If so, does anyone know of any design documentation that covers this scenario?

As far as i know only two switches can form a VSS so you would need two VSS each pair being in a different domain.

Ric,

A VSS is strictly two chassis. However, you can use either two or four supervisors.

As Jon also noted, you can only have 2 switches in a VSS domain.  Make sure domain IDs are different.

I have same scenario ,two C6807 with quoad SUP6T and wonder how we have VSS run in this design ? 

[Ric Hernandez]

I don't think we have the same situation.  I have 4 x 6807 chassis' and each has a SUP6T.  From what I understand, you can only put 2 6807 Chassis' in a VSS pair.  In my case, I'd have to create 2 VSS Pair with Trunks between them.
