FIP Snooping Example

The following figure shows an Aggregator 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.

Figure 1. FIP Snooping on an Aggregator FIP Snooping on Aggregator

In tbe above figure, DCBX and PFC are enabled on the Aggregator (FIP snooping bridge) and on the FCF ToR switch. On the FIP snooping bridge, DCBX is configured 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 is synchronized. For more information about how to configure DCBX and PFC on a port, refer to FIP Snooping

After FIP packets are exchanged between the ENode and the switch, a FIP snooping session is established. ACLS are dynamically generated for FIP snooping on the FIP snooping bridge/switch.
