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 9. FIP Snooping on an 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.
