12 Dell EMC Networking FCoE-to-Fibre Channel Deployment with S4148U-ON in F_port Mode | version 1.0
3.2 LAN topology detail
For the LAN portion of the topology, the S4148U-ON switches are leafs in the data center’s leaf-spine
network. The topology includes the converged connections from the server CNAs and leaf-spine network
connections as shown. The leaf pair forwards production TCP/IP traffic for all devices in the rack. Traffic
destined for other racks is forwarded by the leafs to the spines.

LAN topology
Each S4148U-ON leaf has one 100GbE connection to each Z9100-ON spine upstream. The downstream
connections to the server CNAs carry converged FCoE and LAN traffic as covered in the previous section.
The S4148U-ON leaf switches are configured as a Virtual Link Trunking (VLT) pair, with the VLT interconnect
(VLTi) also using 100GbE connections.
Note: VLT is used for LAN traffic only, and FCoE traffic is not forwarded across the VLTi. When the FCoE
VLAN is added to the vfabric, it is automatically removed from the VLTi. This can be confirmed with the
show vlan command.
