vss- requirements

[veerabhaskarmutyala]

Can i use a 6504 and 6510 with sup-720 and 6510 with bland 8 and 9 having link cards ws-f6700. Just wondering do the IOS versions needs to be matched as well. My point is two physical chassis does not need to be identical in the type of modules installed or even type of chassis.

Thanks

For VSS, you have to use Sup-720-VS.  You cannot use Sup-720.

You also have to use the same exact IOS for both devices.

Likely buried somewhere in Jon's link, but you need 10 gig for the link(s) between the two 6500s and you can not use a 6704 line card (for the "special" cross link).
