Spaning tree Not working On L2 Links

 

  Hi,

   I am facing problem in spaning tree over L2 links between my core switch in braanch to data centre switch, please find my network digram for your understanding,
 

  

  1) we have two 4500 switches in my HO as a core there are two links are connected between them & configured as a port channel.

    2) We have some server which are co locate in nearest DATA center to access that server from HO we have two L2 link between Ho & DATA center

   3) but we are facing issue in spanning tree at the end of HO switch port stat is showing forwarding state in Active switch as well standby switch & in DATA center we are facing the same problem,

     is there any challenges for spanning tree over L2 links?
