FCoE Transit Configuration Example
The following illustration shows an MXL switch used as a FIP snooping bridge for FCoE traffic between an
ENode (server blade) and an FCF (ToR switch). The ToR switch operates as an FCF and FCoE gateway.
In this example, DCBx and PFC are enabled on the FIP snooping bridge and on the FCF ToR switch. On
the FIP snooping bridge, DCBx is configured as follows:
Figure 38. FIP Snooping on an MXL 10/40GbE Switch Configuration Example
• A server-facing port is configured for DCBx in an auto-downstream role.
• An FCF-facing port is configured for DCBx in an auto-upstream or configuration-source role.
The DCBx configuration on the FCF-facing port is detected by the server-facing port and the DCB PFC
configuration on both ports is synchronized. For more information about how to configure DCBx and
PFC on a port, refer to the Data Center Bridging (DCB) chapter.
