VPC and 2960-x stack!

[fly]

Dear Sir/Madam,

       is there any problem when i connect two stack 2960-x to nexus 5672UP by using VPC?

       customer don't like nexus 2k, so we place two 2960-x on top of rack ,  and make stack of two 2960-x together, and  two 10G uplink(one 2960-x has one 10G) connect to two nexus 5672UP separately. and server has two 1G port and connect to two 2960-X separately by using LACP etherchannel.

       and two 5672UP connect to two nexus 7010 by using VPC.

    so from server, access switch 2960-x. nexus 5672up,nexus 7010,  we can built a no spanning tree topology.

     Is there any problem in this design?

 thank you

Tom

HI Tom,

i don't see any design problem with the above topo, it should work.

But i want to know  what u mean by "no spanning tree topology" ?

Thanks,

Muthu.

Hi Muthu,

   Thank you!

   Customer want to use VPC and using spanning tree just as a backup.

   If we choose standalone 2960-x at ToR and use VPC, we must connect two 10G for each 2960-X.

   and Server can't connect two standalone 2960-X.  So i choose stack of two 2960-x at access-layer.

   and from access-switch---distribute nexu 5672up---core nexus 7010 , we can use VPC,

   Thank you!
