Figure 34. MX5108n – LAN using QSFP28 ports in breakout mode
Figure 35 shows how the MX5108n can add FCoE functionality to an existing LAN-only
topology. The MX5108n is configured to operate in FSB mode. The MX5108n snoops FIP
packets on FCoE-enabled VLANs and discovers the following information:
• End nodes (ENodes)
• Fibre channel forwarder (FCF)
• Connections between ENodes and FCFs
• Sessions between ENodes and FCFs
