Stacking two blade enclosure with conenction of all uplink ports from the all VC

Mohammed had a Multi-Enclosure Stacking (MES) stacking question:

 

*******************

 

Dear Experts

            We have a customer with the following configuration....

  • Two blade enclosures stacking
  • Uplink ports are connected as the following
    • ENC01--- VC01 port1 and port 2---- SUS A--- Cisco switch A ----both ports are active status from the VC
    • ENC02 –VC02 port 1 and port 2 ----SUS B---Cisco Switch B  ----   both ports are active status from the VC

Then the customer connected additional ports to the switch as the following

  • ENC01 --- VC02 port 1 and Port 2 SUS B ---  Cisco Switch B----both ports become standby from VC
  • ENC02----VC01 port1 and port 2 SUS A ---    Cisco switch  A  ---- both ports become standby  from the VC

My question here , the other two additional connections status as standby , it is correct , and how can we make them active  ... note that from the cisco switch we added the additional ports to the same port channel group ...

What you are seeing sounds exactly like what you’d expect.  In order to make them all active, you’d need to define an Shared Uplink Set (SUS) 3 and SUS 4.  All links are active ONLY when it’s a contention between  a single VC module and a single switch (or virtual switch, in the case of Intelligent Resilience Fabric (IRF)).

Any other help for Mohammed??
