Hi,
this are two different plattforms and can't work MCT.
The VDX uses Logical chassis Mode .
Extreme VCS Logical Chassis allows organizations to manage an entire VCS fabric as a
single switch, enhancing the overall availability and reliability of the network. This single
point of management eliminates the need to manually configure and manage each
switch, simplifying management, lowering operational costs, and reducing configuration
errors. In addition, it enables organizations to push software upgrades across the fabric
with a single command, accelerating deployment. VCS Logical Chassis also provides a
single view of the fabric, allowing centralized monitoring and troubleshooting that
minimizes time to repair network issues ....
Hope that helps
Regards
Michael
