FCoE Transit Configuration ExampleThe following illustration shows a switch used as a FIP snooping bridge for FCoE traffic between an ENode (server blade) and an FCF (ToRswitch). The ToR switch operates as an FCF and FCoE gateway.Figure 41. Configuration Example: FIP Snooping on a SwitchIn this example, DCBx and PFC are enabled on the FIP snooping bridge and on the FCF ToR switch. On the FIP snooping bridge, DCBx isconfigured as follows:• 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 issynchronized. For more information about how to configure DCBx and PFC on a port, refer to the Data Center Bridging (DCB) chapter.The following example shows how to configure FIP snooping on FCoE VLAN 10, on an FCF-facing port (1/5/1), on an ENode server-facingport (1/1/1), and to configure the FIP snooping ports as tagged members of the FCoE VLAN enabled for FIP snooping.Example of Enabling the FIP Snooping Feature on the Switch (FIP Snooping Bridge)Dell(conf)# feature fip-snoopingExample of Enabling FIP Snooping on the FCoE VLANDell(conf)# interface vlan 10Dell(conf-if-vl-10)# fip-snooping enableExample of Enabling an FC-MAP Value on a VLANDell(conf-if-vl-10)# fip-snooping fc-map 0xOEFC01NOTE: Configuring an FC-MAP value is only required if you do not use the default FC-MAP value(0x0EFC00).FIP Snooping 327
