Hi all,
I'm working on a network topology as following
![dfb65a1210c745548d61c1af28961557_RackMultipart20180910-26242-150cncp-Dell-Brocade_Topology_inline.jpg dfb65a1210c745548d61c1af28961557_RackMultipart20180910-26242-150cncp-Dell-Brocade_Topology_inline.jpg](/t5/image/serverpage/image-id/3938iA737588708796BDA/image-size/large?v=v2&px=999)
Brocade VDX are configured as VCS Fabric - Logical Chassis mode and also, using VDX6740 I enable FCoE on some interface.
On SAN side, I saw correctly FCoE login from both VDX, so either on interface on rbridge-id 1 and r-bridge 2 while on DELL MXL I/O I can see login only on one r-bridge. 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
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. Do you known if this is possible in this kind of architecture?
Thanks in advance for reply
Best Regards
Beppe
