Both VDX interfaces are configured in same manner. The strange thing is that when I disable ISL links between VDX, so I remove VCS fabric feature, I can see FCoE login from both DELL MXL<BR /> Do you known about some limitation on FCoE over the ISL (or TRILL link). If can be possibile I would connect Dell Switch in Dual Homing with vLag.
