Trunk interface between DELL series S and WS-C3560X-48

[alfredobosca]

Hello,

I had a few issues with STP configuration between DELL and Cisco. On this way I would like to create a VLT in the DELL switches and Stacking with both Cisco switches.

After hard inpection only found out a article that explain as use VLT and VPC that only let me Nexus Devices.

- http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/Dell-Networking-and-Cisco-Spanning-Tree-Interoperability.pdf?forcedownload=true

Anybody knows if is possible to merge VLT and Stacking to prevent STP issues?

Thanks in advance!

That's because VPC is a Nexus feature only, I would use MST or use this documentation for their recommendations. https://supportforums.cisco.com/document/62286/dell-cisco-stp-interoperability-and-recommendations-v20pdf 

Hope that helps!

In this case the Cisco Switch 3560X only has these stp modes:

spanning-tree mode ?
  mst         Multiple spanning tree mode
  pvst        Per-Vlan spanning tree mode
  rapid-pvst  Per-Vlan rapid spanning tree mode

The version is: 15.0(2)SE7

Best regards,
