FIP Snooping Example

The below illustration shows an Aggregator used as a FIP snooping bridge for FCoE trac between an ENode (server blade) and an FCF

(ToR switch). The ToR switch operates as an FCF and FCoE gateway.

Figure 9. FIP Snooping on an Aggregator

In tbe above gure, DCBX and PFC are enabled on the Aggregator (FIP snooping bridge) and on the FCF ToR switch. On the FIP snooping

bridge, DCBX is congured as follows:

• A server-facing port is congured for DCBX in an auto-downstream role.

• An FCF-facing port is congured for DCBX in an auto-upstream or conguration-source role.

The DCBX conguration on the FCF-facing port is detected by the server-facing port and the DCB PFC conguration on both ports is

synchronized. For more information about how to congure 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.
